New Xbox 360 Announced, Kinect Pricing Revealed

Yesterday we brought you our in-depth hands-on with the new 250gb Xbox 360 S, and a few days before we reported that a potential replacement for the 360 Arcade was on the cards. Well, today Microsoft officially announced not only the brand new version of the ‘Arcade’ console, but also full pricing details and bundle information for Kinect.

For the latest version of the 360 Microsoft have dropped the ‘Arcade’ suffix instead naming both the current S and the new machine by their memory capacity. The 4gb Xbox 360 becomes the new entry level console, and will be released on 3rd August in North America, priced at $199.99, and 20th August in the UK for £149.99, with the rest of the world taking delivery of the unit sometime later this month.


This new 360 will have 4gb of flash memory instead of a 250gb hard drive, whilst keeping the full functionality and other features of the 250gb model, including the built in Wi-Fi adaptor. The hard drive used inside the 250gb slim will also be compatible with the new model (in which the expansion bay is empty), although Microsoft currently have no plans to release it separately, or in any other sizes at this point in time. You can probably expect another announcement about this later on down the line.

Like with the 250gb 360 S that launched last month in the US, and last week in the UK, the 4gb version will feature the very same slimmed down design, complete with the trademark chrome highlighting and touch sensitive buttons. However the shiny aesthetics of the 250gb S model has been discarded for a more favourable matt finish, much like the old model 360’s and PS3 Slim.

Along with confirmation of the Xbox 360 Arcade’s replacement Microsoft also announced full pricing details for Kinect, both as a solus bundle (Kinect + game) and as a package with the new 4gb 360 console.


Kinect will be released sometime this November (date to be confirmed) and will come bundled with Kinect Adventures. The device will retail at $149.99 in the US, and £129.99 in the UK. All first-party software will retail for of $49.99, and £39.99 respectively. Third-party games will have no baseline retail price, with the publishers of individual titles being able to set their own price brackets accordingly.

Both the Kinect and 4gb Xbox 360 S console will be available as a package. It will be available the same day Kinect launches and will retail for $299 in the US, and for £249.99 in the UK.

Microsoft also confirmed that around 15 games will be available at launch, with a large selection of first and third-party titles being available.

On a final note, the revelation that the console and Kinect bundle will contain the 4gb version of the machine is perhaps unsurprising.

Previously many people suspected that the Kinect + 360 would contain the higher-end model of the console. However, this simply isn’t the case with Microsoft opting to instead package their entry level model with the device in order to maintain a cheaper price point. Interestingly this puts the machine and Kinect in the same bracket as the stand-alone 120gb PS3.

Feature: Hands-On With The Xbox 360 S

On Friday 16th July gamers in the UK were finally graced with the release of the brand new Xbox 360 S; a slimmer, quieter version of the current Elite model 360, with a 250gb hard drive and built-in wireless adaptor. It comes as no surprise that early sales of the machine have been brisk, with many stores opening up on midnight in order to generate further hype for the launch. And by and large it has been largely successful, bar perhaps the odd complaint of having a faulty hard drive, or trouble with the new machine recognising the Data Transfer cable.


Naturally, I took it upon myself to pick up one of these new slim consoles in order to write this in-depth report for IQGamer, in which we’ll be covering the machine’s design, connectivity, build quality, and of course operating noise.

On first impressions, and before holding the unit for the first time, the 360 S appears better in every single way than the old ‘fat’ models that came before – especially compared to my original 20gb launch unit (just about going strong) – although on further inspection it is clear that not all is quite so perfect. But then again, it doesn’t really matter given the massive improvements that have been made in almost ever area with the new machine.



The first thing you’ll notice is that upon initial viewings the packaging is pretty similar to the one that housed the old 360, featuring the same square shape, whilst instead having bottom-opening flap allowing easy access to the contents inside. If you haven’t seen the old box in a while then the new one looks to be the same size, maybe only slightly smaller. However, side-by-side comparisons show a clear inch or two being cut off the sides, whilst being slightly taller overall.

Seeing as the actual console is almost the same size as the old 360 it isn’t at all surprising to see a similarly sized box that keeps it all together. However it does weigh noticeably less than my 20gb Premium when boxed up, although by no means light, simply commanding less strength in order to lug it from the retail store to the bus stop, and then home than the older model.


Inside, the 360 S is packaged similarly to before, except that now the individual compartments for holding the controller and other accessories are better organised allowing for things to be unboxed and boxed up again more easily. Underneath where the actual console sits are four distinct compartments, each housing the different peripherals that come with the machine. The largest one contains the controller and wired headset, whilst the two on either side contain the power cable and composite lead, along with the scart adaptor. At the end of these three compartments is where the power supply lives.

The overall internal layout is much simpler this time around, thus making it easier to pack away the console if need be in the future. Also, two of the sections are clearly marked with small stickers dictating what should occupy these specific spaces just in case you forget. Yet another improvement over the horridly packaged ‘fat’ model 360.


In terms of the actual console, noticeably, Microsoft have gone to town in producing a sleeker, more high-end looking aesthetic for their new Xbox 360 S. The old matt plastic look has been replaced with a smooth, glossy finish that only comes in black. Chrome highlights provide a small contrast between the black contours synonymous with the Xbox 360 Elite; the new power button and both outer edges of the machine benefiting from this touch of class. Round the back the aesthetics again change slightly, instead becoming a combination of the new shiny gloss design with a slight hint of the old matt finish around the various ports.

Annoyingly, this new shiny design as stylish and sexy as it is, is prone to attracting dust and fingerprints which can cover the machine in seconds if you’re not careful. Likewise, the 360 S also scratches really easily. Even using a fine micro fibre cloth regularly used for cleaning the PSP and ‘fat’ PS3 can leave very slight marks. Although these are only visible in certain lighting conditions and from a specific angle, so its not too much of a problem.


The previous inhaled design remains on the ‘S’, although now it is complemented by a new angular focus with sharpish curves leaning inwards on both the front and back of the machine. Initially this looks somewhat strange, especially when resting the machine in its standard horizontal position. However, standing upright it looks incredibly stylish and far more desirable than the old console. This new look and feel is accentuated by the use of touch-sensitive buttons for powering on/off the unit, and for opening and closing the disc tray, which remains a traditional slot loading drive.

Surprisingly, the new 360 S is still rather heavy, more so than I expected, and the overall build quality is superior to the old versions of the console. However there are some parts of the design which feel decidedly cheap to the touch. Like with the plastic casing on both the top and bottom of the machine, which tends to creak as you hold it. The console also feels a touch softer and more flexible too - no doubt made this way to better enable the plastic to constrict and contract as the internal temperature of the machine heats up during use, and cools down after.



Compared to the old 360, the ‘S’ is only slightly smaller in size covering almost the entire length of the original console, though it is slightly shallower as well. For something rumoured, and sometimes officially recognised as the 360 Slim in passing it’s quite disappointing how similar in size to the original it is, especially when you consider that the power supply is still external. Sony, with their Slim PS3 should really be commended on their engineering prowess seeing as both the power supply and hard drive are both built-in, and the machine itself runs a little bit quieter overall.

Despite this, Microsoft’s first entry into redesigning a console midway through its life-cycle has much to offer, and the use of the old-fashioned slot-loading DVD makes shrinking down the internals that much harder. Effectively how much smaller can you make that drive, is the question you should be asking.

Either way the new ‘S’ variant of the 360 hardware looks far more sophisticated, and highly stylized.


In terms of connectivity the new 360 S features the standard two USB ports situated around the front of the machine, under a flap next to the new rectangular shaped controller sync button. The disc tray remains a slot loader like the previous models of the console, although it is much quieter and feel a tad more solidly built. Round the back you have a further three USB ports, along with an Ethernet port, optical output, one HDMI port, multi-AV out, and a special port design solely for powering and interfacing with the Kinect unit.

Like with the Pro and Elite model 360’s, it is still possible to use the HDMI cable with the AV audio adaptor if you require the option of analogue stereo sound from the machine going into a hi-fi system or external amplifier.

The machine also features the use of a semi-built-in hard drive located on the bottom, or right hand side of the unit depending on whether you have it laying flat or standing up. I say semi-built-in as although the HDD is housed inside the 360 itself, it is fully removable and comes locked away in its own plastic casing. As we first revealed here, the HDD is a Hitachi HTS545025B9SA00 1.5Gbps hard drive which connects to the 360 using a standard SATA connector.


Moving on to the controller, and you can see that Microsoft have made similar aesthetic changes in order for it to match the new style of the console. The entire controller, save for the four face buttons and the Guide button have been made uniformly black. The underside of the pad is now finished in glossy black rather than the matt grey of the Elite and Pro models, or the shiny metallic silver of the Core and Premium units. Both the D-Pad and analogue sticks have also gone through a similar change, appearing black instead of dark grey, while the Guide button has given a shiny chrome finish representative of the highlights present on the console.


Other than the look of the controller not much else has changed. The D-Pad does feel slightly more responsive compared to the one that came with the controller with my launch unit, although it doesn’t appear to have full eight-way precision like the on the Japanese Sega Saturn pad. In that respect, playing fighting games using this new D-Pad is still a chore with certain quarter-circle type movements being incredibly fiddly to pull off. At least all four directions actually work this time around, unlike on my launch 360 controller in which parts of the D-Pad have always been largely unresponsive requiring a heavy push in order for the press to be recognised.

Outside of the console and controller both the hated power supply unit, and AV cables have been given a complete makeover, appearing to match the new styling present for the entire range of ‘S’ accessories and hardware.


Styled in black, with a matt finish, the PSU is now much smaller and lighter than before. Curved in its appearance it can finally be considered stylish for the first time, though more importantly it seems to accompany the main hardware pretty well, rather than looking like an eyesore trailing out from behind the 360. The power cable that goes from the PSU to the 360 also slots into the back of the machine almost effortlessly; a stark contrast with the constant wiggling and pushing required to get it coonected with the old non-HDMI models.


The same principles when it comes to styling have been applied to the AV cables, which now have a more angular look to them. They are less rounded compared to the old ones, but still display just enough of the smooth curves to be consistent with both the 360 brand as a whole while matching the new 360 S console.


Sure enough, from a purely design and aesthetics point of view the new 360 S is lovely, but all that isn’t going to count for much if it still sounds like a Jumbo Jet taking off from Heathrow now, is it? And the less we talk about the noise problems of prior versions of the old console the better.

However Microsoft have made waves with this new design, the newly fabbed Valhalla chipset demonstrating some noticeable decreases in operating temperature, and most importantly, noise, especially when inserting a game disc into the system.

Powering on the console for the first time using the touch sensitive button on the front of the unit, you are almost immediately graced with a fairly loud, but smooth ‘bing’ sound coming from the machine. It’s s very welcoming and goes well with the aesthetic style Microsoft have created for the console, and the new sound effects used in the NXE 360 dashboard.

Reassuringly, this is the most noticeable noise to come from the console at start up.


One of the main complaints about previous models of 360 was the high level of operating noise coming from the machine, especially when a disc-based game was inserted into the system. Installing games onto the hard drive partially solved this problem on the old 360, but now this is no longer required for an all-round quieter experience. Claims by Microsoft of the new unit being ‘whisper quiet’ were initially to be taken with a pinch of salt. However, when idling the new 360 is actually barely audible unless turned on in a completely silent room. By contrast my 20gb launch unit can be heard at all times whether or not a disc has been loaded into the system.

Like with my 20gb Premium, installing games into the new 360 S leads to an even quieter gaming experience. When playing a game via a disc however, the fan speed still ramps up on this new model and the familiar electronic humming noise appears, albeit no longer drowning out the sound coming from the TV. Installing the game means that this never happens, with the fan speed sticking at idling levels for the duration of your gaming session.

Installing games then is still the best possible way to experience just what the 360 can deliver, with less noise leading to greater levels of immersion and less in the way of a distraction. But does the new HDD equate to shorter install times and quicker loading compared to standard disc-based approach?

In short, yes and no. You see whilst I found the new 360 S quicker to load up games off the hard drive I also found it slightly slower in installing them in the first place. Right off the bat I can tell you that average install times for the few games that I tested (Alan Wake, Halo 3, VF5, Gears 2, and Resident Evil 5) was about one to two minutes slower than on my 20gb Premium. Loading times however, were either on par or slightly faster, as was the case when trying out Bungie’s Halo 3 on both machines.

This is an interesting find to say the least, but also somewhat confusing as I’m not too sure why it should be happening. Could the size of the hard drive have something to do with it? Or perhaps something to do with cache size and speed. Maybe we shall do a proper investigation into this later on at IQGamer, as our initial results are surprising.


In conclusion, from all my time spent with the new Xbox 360 S I can definitively say that the machine IS what the original 360 console should have been. Even though it isn’t that much smaller – in fact it’s pretty much the same size – it looks a whole lot nicer and runs far quieter than any of the old models. It should also be noted that we shouldn’t be seeing any more of that RROD death problem which plagued most original and Falcon chipset 360’s, not least of all because the rend ring physically doesn’t exist on the new model, but simply due to the reductions in operating temperature and better cooling provided by the 45nm Valhalla revision to the CPU and GPU.

So, in the end the 360 S represents an improvement over the previous design in almost every way, minus perhaps the shiny finish which will certainly see the unsightly disfiguration of many consoles before reaching the end of their natural life-cycle, and shows how much time has been spent consolidating the hardware, and making changes where necessary.

Outside of the sleeker look, quieter operating noise, and built in wi-fi and 250gb hard drive there isn’t much to sound off about, and a much to be content with. Some may complain that the machine isn’t really a ‘slim’ version of the console, but given the technological and financial constraints it is unlikely at this point in time that Microsoft could have done any better. The end result is a highly polished successor to the long running line of original Xbox 360 consoles, and a brief look at the future of the platform.

New Xbox 360 S 'Arcade' Coming Soon?

The brand new 250GB Xbox 360 S was just the beginning of Microsoft’s strategy for the their remodelled version of the console. After replacing the now discontinued 360 Elite the company now apparently have plans to reintroduce an arcade version of the 360 based on the new slim design.


According to Amazon.de an new "Xbox 360 4GB Arcade System Bundle" will be released on the 20th August and comes with a speculated 149 Euro price point. However the news isn’t exactly fresh, as Microsoft has recently discussed their interest in releasing another Arcade model 360 based on the new design exclusively for the US market, although European support seems at this point to be out of the question – officially at least.

In an interview with Eurogamer, Microsoft’s Neil Thompson stated that the company had no plans to launch another model of the new 360 in Europe, instead focusing on the current 250GB slim and the continuation of the original 360 Arcade unit.

"The Elite model we'll slowly phase out, but we're continuing with the Arcade model as it stands,"

This response was the exact opposite to what Microsoft’s US arm has said in the past, although that would explain the current situation with many retailers in which the Elite model is completely sold out, but the Arcade in comparison is still reasonably stocked.

The other point is that he could mean that the existing Arcade SKU will be moved into the slim design but without the 4GB storage space listed by Amazon, being more or less an exact continuation of the current system. Of course this is very unlikely, and all signs simply point to his stance being more centred around the company wanting to make a proper official announcement on the matter nearer the time, and after supplies of the old 360 Arcade have run dry.

Either way we should find about this ‘new’ version of the 360 Arcade soon enough.

Tech Report: A Look At The EDRAM On Valhalla

We brought you our inside the 360 slim feature just over a week ago, revealing the internal layout of the console, and the all important details surrounding the chip and die shrinks contained within. However, one piece of the puzzle was missing – both the size and exact whereabouts of the EDRAM in the CPU/GPU package. This is something which is of particular interest seeing as this piece of silicon has always been behind in terms of process node changes, and has yet to be intergrated into the same die as the GPU.

This still seems to be the case - as you will see in the image of the console’s motherboard below – that the EDRAM is a separate entity from both the CPU/GPU combo, which now appears to be housed on a single die.


So, both the GPU and CPU are firmly on a single die, and the EDRAM is once again separate, all of which is housed on a single package, codenamed Valhalla. The CPU/GPU is now on a 45nm process node, although the EDRAM looks to be noticeably larger. The overall die size is some 34% smaller than the Jasper chipset’s CPU and GPU combined, inc EDRAM. And is 53% smaller than the ones used in the first 360 chipsets. For reference the Jasper chipset featured both the CPU and GPU at 65nm, whilst the original 360 featured 90nm versions of both chips.

From the above image it doesn’t look like the EDRAM has been fabbed at 45nm – it’s far too large in size for that. Instead all signs point to it being around 55nm or 65nm as speculated in our original article from a couple of months back. Interestingly, this is opposite to what the latest pieces of scattered information were saying in our later article – in which a 45nm EDRAM was hotly expected to be included.

Why the difference in die size compared to the other chips then? Well, the EDRAM itself has always been behind on process reductions, with complications in shrinking the chip being the main reason behind such slow comparative progress being made. Cost is also another factor. It could be that it is simply too expensive to economically reduce the EDRAM in size whilst obtaining optimal yields during production (a certain number of chips produced are unusable). Plus, the slower progress of reliable die shrinks to the EDRAM could have also held back development of the Valhalla CPU/GPU combination, with the complex integration of the EDRAM at a different size posing unnecessary problems and expenditure.

Integrating all three chips (CPU, GPU and EDRAM) would take the cooperation of ATI, NEC and IBM in order to make it happen given the increased complexity required for such a design. The cost of which would have been larger than simply producing three separate chips, or in this case two on one package. Another issue is getting the design and final production grade silicon ready on time, and given the increased complexity it is unlikely that this was ever going to happen. Effectively, all things considered, the cost/benefit ratio to having not only die shrinks, but also complete integration of all three chips on one die was perhaps too poor for consideration.

That’s not to say that later on down the line the EDRAM won’t be included in another internal revision of the 360, because it is very likely that Microsoft are working to do exactly that at some point in the future. It is possible for this to happen now, just not quite being the cost saving measure they are after at this point in time. Maybe with the next, and possibly last revision to the hardware, we will find that all three chips will have been completely integrated into a single die, rather than a single package. At that point, we expect that the EDRAM along with the now combined CPU/GPU will all be produced on the same process node.

With the current Xbox 360 S (slim) we have here what is clearly the best price/performance ratio available at this point in time with regards to heat reduction, and overall saving in silicon. Whatever changes we (and many others) might speculate, there is no doubt that Microsoft have done their very best in producing the most efficient, and cost effective version of the 360 to date. It is also the quietest and most solidly built too, which is not something you can really say about the console before the Slim’s arrival.

Tech Report: Inside The Xbox 360 Slim

Earlier on in the week at E3 in Los Angeles Microsoft unveiled the brand new slim version of the Xbox 360, finally ending rumours of a new outer casing design and internal component revisions. We first reported on the 360 slim way back in march when photos of its motherboard were leaked onto the internet, showcasing what looked like a combined CPU/GPU on a single chip or die, and boasting a more efficient single fan cooling system. Now, with the console starting to filter into homes and into the hands of various tech-savvy enthusiasts, we can finally take a look under the hood of the machine and its internals.

Those of you expecting any last minute revelations are likely to be disappointed, as much of what we said back in our original 360 slim report was pretty much 100% correct. The use of a combined CPU/GPU and EDRAM, internal fitting hard drive, optical output, and external power supply are all correct and present, as is too the lack of any memory card slots or ability to use the old 360 hard drives on the new unit.


Looking at the final retail console’s motherboard (pics of which are quickly circulating around online) we can see that this latest revision of the 360 console uses the long-time rumoured Valhalla chipset, which consists of a CPU, GPU, and EDRAM all on one package. I say package as each of the chips are single entities housed all on one die, with the CPU and GPU produced on a 45nm process node.

As for the EDRAM, well it looks like that might also be produced at 45nm like the other two chips, although this isn’t confirmed. Last we heard TSMC were having trouble shrinking down the EDRAM on a 45nm process so we surmised that it might have to be done on something like 55nm. This now doesn’t seem to be the case, with sources pointing to the chip being finally fabbed at 45nm, which also goes hand in hand with reports that the Valhalla chipset as a whole is being manufactured at the Global Foundries owned Chartered Semiconductor.

Anyhow, the brand new single die design means that the chip runs a lot cooler than previous versions, which are larger and more power hungry. The advantage is that the new slim can be cooled with just one fan, and an efficient heat dissipation system build around that design. To that end the fan covering the CPU/GPU/EDRAM package is housed directly below the vents situated on the top of the outer casing, along with the actual chip package itself. The fan draws in cool air from the top of the console and then blows out heated air through the sides, dissipating the heat far more efficiently than previous models were able to do.

Other than the brand new combo chip package, the motherboard has also seen a complete re-design looking a lot more streamlined than before. Much of the excess fat has been cut, and components that were no longer needed have been cut away leaving a less cluttered design behind. Again, less stuff needed to be powered equals less overall heat, so there are less likely to be any issues of additional components creating heating issues in such an enclosed pace.

One thing that does appear to be the same as in the previous Jasper model 360, is the use of those 1 Gbit Samsung DDR3 RAM chips for the system’s unified memory. With a complete revision to the CPU and GPU, along with a streamlined motherboard, one might have also expected some kind of revised memory system as well. That doesn’t appear to be the case, and although two GDDR5 sticks would be preferable, Microsoft would then have needed to replace the existing memory controller as well. Plus at this point the use of GDDR5 isn’t at all feasible with low production numbers, and the actual cost saving using the new chips might not actually be that much cheaper, if at all at present.

Perhaps just a little too much work for minimal results, especially when it really isn’t needed as the new unit already draws far less power than before. Plus, it’s likely that MS will be making a large cost saving once these fabs ramp up production of the new components found inside the console.


Moving on, unlike previously speculated the 360 slim doesn’t have a built-in internal hard drive. Instead the HDD whilst technically being internal, is also completely removable and is housed inside a custom casing created by MS, which then lives inside the back of the machine. The new HDD being used is a Hitachi HTS545025B9SA00 1.5Gbps SATA hard drive, running at a speed of 5400RPM with an 8MB buffer.

Seeing as the new HDD connects via a standard SATA port it might be possible to hook up larger capacity drives to the console, either by swapping out the hard drive from inside the MS casing, or by simply connecting one externally via the SATA port. So far no one has tried this just yet, but the modding potential is definitely there for those of you out there who are skilled enough to do so.

Once again the system’s power supply is external. As we found no evidence of it being internal in our report on the motherboard back in march, that isn’t really so surprising, and given the cooling problems of previous units probably for the best. Thankfully though the PSU is much smaller than before, and is more stylish looking too – smooth curves and all. Well, it is as stylish as a PSU can be.


Lastly, and we though this was worth a recap over our initial reveal of the unit, is the inclusion of an input for connectivity with Kinect situated above the Ethernet port. This port both powers the Kinect device along with interfacing it with the 360 console for data transfer, and processing on the 360’s end. Users of any older model 360 will have run two separate cables in order to use the Kinect; One which plugs into a USB port on the 360 to interface with the unit, and another from the Kinect going into the plug socket in order to power the device.

Clear signs point to a 360 + Kinect bundle at some point, and the motherboard and overall design for the slim console shows that this was factored into it.

Overall, Microsoft has done well in creating a streamlined and power efficient revision of the 360 console. What we have here is a rather good combination of chip/die shrinks with improved cooling and heat dissipation, meaning we should see far less in the way of hardware failures, and of course high-levels of operating noise. It’s a nicely engineered piece of kit, both internally and externally, that finally presents the format as a premium product very much in same vein as the PS3.

The brand new 360 Slim hits retailers on July 16th in the UK, with most retailers now taking preorders for the console. It is priced at £199.99, the same as the current Elite model it replaces, which along with the Arcade SKU will see a price drop the same day the slim is released.

IQGamer will of course be bringing you our hands-on with the new unit as soon as possible, hopefully right around the time of launch, or very soon after.

Microsoft Announces 360 Slim

Earlier today at their pre-E3 press conference in LA Microsoft officially unveiled a brand new version of the 360 console, marking an end to leaked motherboard photos and numerous unconfirmed reports of its existence.


The 360 Slim is a smaller, shorter, and quieter redesign of the current Super Elite model, boasting a 250gb hard drive, built-in 802.11n Wi-Fi adaptor, extra USB ports, a separate optical output for surround sound users, and a port for hooking up the Kinect motion sensor.

Compared to current models of 360 the slim features a shiny gloss black finish with chrome highlights, and also has touch sensitive buttons much like the original chunky PS3’s. Internal revisions to the hardware are obviously present, with a shrunk down CPU/GPU combo and one single fan responsible for cooling the unit, resulting in the console being "whisper quiet" according to Microsoft.

Retailers in the US are expecting to receive stock of the new console later on this week for immediate sale, whilst Europe is said to be getting the machine on 16th July.

We shall be providing a more comprehensive look at the hardware later on this week after the mayhem of E3 has subsided.

Could This Be 360 Slim?

There have been rumours about an eventual slim line version of the 360 for a few years now, with various sources and unsubstantiated reports sighting plans for an all-in-one CPU, GPU and EDRAM chip, coupled together in one massive internal revision of the 360 console. That revision was allegedly known as Valhalla, which would see both the main processing components of the 360, along with the EDRAM, shrunk down into one power-efficient little chip, bringing down the cost of production, and allowing for a complete design makeover.

At the time, it was impossible to expect such a revision to appear for at least a couple of years, given the slow and struggling process of being able to shrink down the EDRAM in line with both the CPU and GPU inside Microsoft’s console. So much so, that only last year were the fabrication plants at TSMC were able to significantly reduce the size of the 360’s GPU, resulting in the much more reliable ‘Jasper’ revision of the hardware.

Yesterday however, two leaked photos seemed to show that those initial problems have in fact been alleviated, now allowing a combined CPU, GPU and EDRAM on a single chip, or at least on one single die containing all three separate chips, albeit much smaller in size than before. It also shows what looks like a complete re-engineering of the 360 motherboard into a much more compact form, at least one third smaller than the current design, and a glimpse into the potential release of a slim 360 console.


The two images in question were released on a Chinese tech forum, A9VG, and shows what looks like a genuine reworking of the 360 motherboard, while also revealing various other changes inherent in the basic design of the new console. The first photo above, shows the actual shape of the motherboard it self, demonstrating the new small size, at the same time teasing us with an image of a smaller combined chip underneath a stock Coolermaster cooling fan.

From what we can see, it’s pretty obvious to us, that use of an off the shelf cooling fan isn’t likely to be part of the final retail unit of this 360 slim. Instead all signs point to these photos being of a test unit, still under development and in the last stages of trialing, before being cleared for a final production to start. However what’s interesting is that the second photo clearly shows us a single CPU and GPU package on what could be a single chip, along with changes to the motherboard showing perhaps what kind of hard drive they will be using for the unit, in addition to changes with regards to the type of audio outputs available on the machine in this latest model.


This second shot shows us all of the motherboard and its features in clear view, most noticeably confirming that the CPU, GPU and EDRAM sits together on either a single chip, or more likely a single die, with the each of the three chips being separate entities integrated onto it. My reasoning behind this is that integration of the EDRAM and GPU into a single chip would actually require a major redesign in order to fit into the shader core, whilst also having to be produced on the same process node. Basically it would have to be fabricated at the same size as the main GPU, something that is still a problem at the TSMC from what I’ve been hearing.

Another thing, is that due to the photographer’s lack of removing the heat spreader, we don’t really know for sure just what is lurking underneath, or what process node the chip is on. I’m pretty sure it would have to be at least 45nm, but then it would mean that the CPU, GPU and EDRAM are definitely still separate chips housed in one die, rather than a single chip. It’s highly unlikely that the EDRAM could be processed at a 45nm; instead more along the lines of 55nm, making this part separate at least from the CPU and GPU.

Interestingly the motherboard looks to contain parts required for additional features to be present on the slim 360. Now, these are pretty much a reworking on the things which the current machine already has, just done in a different way. The first thing that comes to mind is the extra SATA connector available for use on the board, bringing the count up to two. On the current 360 the board only has a single connector, used for the DVD Rom drive, whereas here on the slim, an inclusion of a second seems to hint at an internal hard drive storage solution, or at least a new type of external connecting HDD.

An internal drive is unlikely, as it would prevent an upgrade path for arcade users, whilst also preventing Microsoft from selling larger hard drives later on down the line. However, they could in theory break free, and make a fresh start with the slim, whilst still producing HDDs for existing 360 owners. In fact, that is probably the most obvious choice, as a clean break is the only way for them to achieve a cost effect new hardware design.

Also there’s no sign of the mounting holes used to fix the existing DVD drive into the unit, and at any rate, it would not fit into the new slim design, leading me to believe that either MS are planning to give us a shiny slot loading type drive, or are simply moving its position around a bit. Perhaps they will use some kind of top-loading system for the slim, although more likely is another version of the current slot-loading drive found in the fat 360s.

Memory card readers have also been cut down to one unit now, and there is no sign of any inbuilt wireless adaptor, which is disappointing. I guess MS are making too much of a killing by selling the existing Wireless N adaptor at 60 quid, and would rather continue with their lucrative margin on accessories. However, they have seen fit to at last include an optical output on the back of the new unit, meaning the end of buying the overpriced audio dongle for surround sound when using a HDMI cable without an HDMI compatible amplifier.

From what we gather, the power supply seems to be another external jobbie, unlike the tightly integrated PSU of the slim PS3, which although mildly disappointing, at least allows the machine to be potentially much smaller than the current design. In that respect we expect the overall size of this new 360 to be smaller and more representative of its unofficial ‘slim’ moniker than with the latest PS3. You could say that from the motherboard photos it could well end up looking a little bit like the Dreamcast, just with a stylish slot loading drive instead of an outdated top-loader design.

That’s pretty much all we know right now, not being able to shed anymore light on that interesting single chip/die CPU, GPU and EDRAM combination, or to ascertain whether this latest revision of the 360 hardware is in fact a slim console, or just another revision, albeit a massively more drastic one.

All signs do point to something major happening though, with Microsoft advertising for a Motherboard Design Engineer for the Xbox console, who is being described as being responsible for "aggressive cost reduction of the console throughout the life of the product”, and at the same time, past candid statements from company execs, which detailed plans for a brand new version of the 360 console due to release at the same time as Natal.

As per usual Microsoft declined to talk about the matter, issuing the same “we don't comment on rumour and speculation” line heard many times before, but this isn’t the first time such unofficial leaked information has provided the solid background for hardware confirmation. PS3 slim was revealed in much the same way many months before it was announced and released.

Ultimately we don’t know whether this is going to be a 360 slim for sure, though all signs do point that way, and in any case, Microsoft like Sony, wouldn’t want to reveal anything too soon as not to disrupt current sales of the existing 360 console, especially many months before the new machine is ready to go.

Either way, it won’t be long before we find out even more details, and we're willing to bet that unofficial leaks will be the leading source of information long before any official announcement takes place.
