It has been over 20 years since Atari launched their Jaguar system, the last piece of hardware that company would make; until now perhaps. There was a mysterious announcement and the launch of a website with little more information than a movie featuring rendered wood grain and plastic. You can sign up at ataribox.com to become the first to know, if Nintendo decides to share more information. It will be very interesting to see what components they have picked to run this new console, considering the high specifications of the new Xbawkx they will either need high end silicon or a much lower price to compete. The video is down below and you can pop over to The Inquirer for more speculation if you so desire.
"The iconic company, which has had more lives than Garfield in a blender, is to release the Ataribox, which so far is shrouded in mystery, aside from the classic wood panelling that lovers of the 2300 and 2600 will know only too well."

Of the eight Jaguar cores that Sony added to the PlayStation 4 APU, two were locked down the console's operating system and other tasks. This left the developer with six to push their workloads through. This was the same as the Xbox One until Microsoft released an update last year, which unlocked one to give seven.
NeoGAF users report that, allegedly, PlayStation 4 games can now utilize seven of the eight cores after a recent SDK update from Sony. They source a recent changelist for FMOD, a popular audio management library for PC, mobile, and console platforms, which references targeting “the newly unlocked 7th core.”
Since this is not an official Sony announcement, at least not publicly, we don't know some key details. For instance, is the core completely free, or will the OS still push tasks on it during gameplay? Will any features be disabled if the seventh core is targeted? How frequently will the seventh core be blocked, if ever? What will happen if you block it, if anything? The Xbox One is said to use about 20% of their unlocked seventh core for Microsoft-related tasks, and claiming the remaining 80% is said to disable voice recognition and Kinect features.
The Xbox One and PlayStation 4 are interesting devices to think about. They go low frequency, but wide, in performance, similar to many mobile devices. They also utilize a well-known instruction set, x86, which obviously has a huge catalog of existing libraries and features. I don't plan on every buying another console, but they move with the industry and has a fairly big effect on it (albeit much less than previous generations).

Beema and Mullins have arrived and by now you must have read Josh's coverage but you might be aching for more. The Tech Report were present at the unveiling and came prepared, with a USB 3.0 solid-state drive containing their own preferred testing applications and games. Not only do you get a look at how the Mullins tablet handled the testing you can see how it compares to Kabini and Bay Trail. Check out the performance results as well as their take on the power consumption and new security features on the new pair of chips from AMD which come bearing more gifts than we had thought they would.
"A couple weeks ago, AMD flew us down to its Austin, Texas campus for a first look at Mullins and Beema, two low-power APUs aimed at the next wave of Windows tablets and low-cost laptops. Today, we're able to share what we learned from that expedition—as well as benchmarks from the first Mullins tablet."

AMD Makes some Lemonade...
I guess we could say that AMD has been rather busy lately. It seems that a significant amount of the content on PC Perspective this month revolved around the AMD AM1 platform. Before that we had the Kaveri products and the R7 265. AMD also reported some fairly solid growth over the past year with their graphics and APU lines. Things are not as grim and dire as they once were for the company. This is good news for consumers as they will continue to be offered competing solutions that will vie for that hard earned dollar.
AMD is continuing their releases for 2014 with the announcement of their latest low-power and mainstream mobile APUs. These are codenamed “Beema” and “Mullins”, but they are based on the year old Kabini chip. This may cause a few people to roll their eyes as AMD has had some fairly unimpressive refreshes in the past. We saw the rather meager increases in clockspeed and power consumption with Brazos 2.0 a couple of years back, and it looked like this would be the case again for Beema and Mullins.
I was again expecting said meager improvements in power consumption and clockspeeds that we had received all those years ago with Brazos 2.0. Turns out I was wrong. This is a fairly major refresh which does a few things that I did not think were entirely possible, and I’m a rather optimistic person. So why is this release surprising? Let us take a good look under the hood.
AMD Brings Kabini to the Desktop
Perhaps we are performing a study of opposites? Yesterday Ryan posted his R9 295X2 review, which covers the 500 watt, dual GPU monster that will be retailing for $1499. A card that is meant for only the extreme enthusiast who has plenty of room in their case, plenty of knowledge about their power supply, and plenty of electricity and air conditioning to keep this monster at bay. The product that I am reviewing could not be any more different. Inexpensive, cool running, power efficient, and can be fit pretty much anywhere. These products can almost be viewed as polar opposites.
The interesting thing of course is that it shows how flexible AMD’s GCN architecture is. GCN can efficiently and effectively power the highest performing product in AMD’s graphics portfolio, as well as their lowest power offerings in the APU market. The performance scales very linearly when it comes to adding in more GCN compute cores.
The product that I am of course referring to are the latest Athlon and Sempron APUs that are based on the Kabini architecture which fuses Jaguar x86 cores with GCN compute cores. These APUs were announced last month, but we did not have the chance at the time to test them. Since then these products have popped up in a couple of places around the world, but this is the first time that reviewers have officially received product from AMD and their partners.
Low Power and Low Price
Back at CES earlier this year, we came across a couple of interesting motherboards that were neither AM3+ nor FM2+. These small, sparse, and inexpensive boards were actually based on the unannounced AM1 platform. This socket is actually the FS1b socket that is typically reserved for mobile applications which require the use of swappable APUs. The goal here is to provide a low cost, upgradeable platform for emerging markets where price is absolutely key.
AMD has not exactly been living on easy street for the past several years. Their CPU technologies have not been entirely competitive with Intel. This is their bread and butter. Helping to prop the company up though is a very robust and competitive graphics unit. The standalone and integrated graphics technology they offer are not only competitive, but also class leading in some cases. The integration of AMD’s GCN architecture into APUs has been their crowning achievement as of late.
This is not to say that AMD is totally deficient in their CPU designs. Their low power/low cost designs that started with the Bobcat architecture all those years back have always been very competitive in terms of performance, price, and power consumption. The latest iteration is the Kabini APU based on the Jaguar core architecture paired with GCN graphics. Kabini will be the part going into the FS1b socket that powers the AM1 platform.
Kabini is a four core processor (Jaguar) with a 128 unit GCN graphics part (8 GCN cores). These APUs will be rated at 25 watts up and down the stack. Even if they come with half the cores, it will still be a 25 watt part. AMD says that 25 watts is the sweet spot in terms of performance, cooling, and power consumption. Go lower than that and too much performance is sacrificed, and any higher it would make more sense to go with a Trinity/Richland/Kaveri solution. That 25 watt figure also encompasses the primary I/O functionality that typically resides on a standalone motherboard chipset. Kabini features 2 SATA 6G ports, 2 USB 3.0 ports, and 8 USB 2.0 ports. It also features multiple PCI-E lanes as well as a 4x PCI-E connection for external graphics. The chip also supports DisplayPort, HDMI, and VGA outputs. This is a true SOC from AMD that does a whole lot of work for not a whole lot of power.
The 7 Year Console Refresh
The consoles are coming! The consoles are coming! Ok, that is not necessarily true. One is already here and the second essentially is too. This of course brings up the great debate between PCs and consoles. The past has been interesting when it comes to console gaming, as often the consoles would be around a year ahead of PCs in terms of gaming power and prowess. This is no longer the case with this generation of consoles. Cutting edge is now considered mainstream when it comes to processing and graphics. The real incentive to buy this generation of consoles is a lot harder to pin down as compared to years past.
The PS4 retails for $399 US and the upcoming Xbox One is $499. The PS4’s price includes a single controller, while the Xbox’s package includes not just a controller, but also the next generation Kinect device. These prices would be comparable to some low end PCs which include keyboard, mouse, and a monitor that could be purchased from large brick and mortar stores like Walmart and Best Buy. Happily for most of us, we can build our machines to our own specifications and budgets.
As a directive from on high (the boss), we were given the task of building our own low-end gaming and productivity machines at a price as close to that of the consoles and explaining which solution would be superior at the price points given. The goal was to get as close to $500 as possible and still have a machine that would be able to play most recent games at reasonable resolutions and quality levels.

Tagged: Puma, Mullins, mobile, Jaguar, GCN, beema, apu13, APU, amd, 2014
AMD’s APU13 is all about APUs and their programming, but the hardware we have seen so far has been dominated by the upcoming Kaveri products for FM2+. It seems that AMD has more up their sleeves for release this next year, and it has somewhat caught me off guard. The Beema and Mullins based products are being announced today, but we do not have exact details on these products. The codenames have been around for some time now, but interest has been minimal since they are evolutionary products based on Kabini and Temash APUs that have been available this year. Little did I know that things would be far more interesting than that.
The basis for Beema and Mullins is the Puma core. This is a highly optimized revision of Jaguar, and in some ways can be considered a new design. All of the basics in terms of execution units, caches, and memory controllers are the same. What AMD has done is go through the design with a fine toothed comb and make it far more efficient per clock than what we have seen previously. This is still a 28 nm part, but the extra attention and love lavished upon it by AMD has resulted in a much more efficient system architecture for the CPU and GPU portions.
The parts will be offered in two and four core configurations. Beema will span from 10W to 25W configurations. Mullins will go all the way down to “2W SDP”. SDP essentially means that while the chip can be theoretically rated higher, it will rarely go above that 2W envelope in the vast majority of situations. These chips are expected to be around 2X more efficient per clock than the previous Jaguar based products. This means that at similar clock speeds, Beema and Mullins will pull far less power than that previous gen. It should also allow some higher clockspeeds at the top end 25W area.
These will be some of the first fanless quad cores that AMD will introduce for the tablet market. Previously we have seen tablets utilize the cut down versions of Temash to hit power targets, but with this redesign it is entirely possible to utilize the fully enabled quad core Mullins. AMD has not given us specific speeds for these products, but we can guess that they will be around what we see currently, but the chip will just have a lower TDP rating.
AMD is introducing their new security platform based on the ARM Trustzone. Essentially a small ARM Cortex A5 is integrated in the design and handles the security aspects of this feature. We were not briefed on how this achieves security, but the slide below gives some of the bullet points of the technology.
Since the pure-play foundries will not have a workable 20 nm process for AMD to jump to in a timely manner, AMD had no other choice but to really optimize the Jaguar core to make it more competitive with products from Intel and the ARM partners. At 28 nm the ARM ecosystem has a power advantage over AMD, while at 22 nm Intel offers similar performance to AMD but with greater power efficiency.
This is a necessary update for AMD as the competition has certainly not slowed down. AMD is more constrained obviously by the lack of a next-generation process node available for 1H 2014, so a redesign of this magnitude was needed. The performance per watt metric is very important here, as it promises longer battery life without giving up the performance people received from the previous Kabini/Temash family of APUs. This design work could be carried over to the next generation of APUs using 20 nm and below, which hopefully will keep AMD competitive with the rest of the market. Beema and Mullins are interesting looking products that will be shown off at CES 2014.
Kabini is a pretty nifty little chip. So nifty, AMD is actually producing server grade units for the growing micro-server market. As readers may or may not remember, AMD bought up SeaMicro last year to get a better grip on the expanding micro-server market. While there are no official announcements from SeaMicro about offerings utilizing the server-Kabini parts, we can expect there to be sooner as opposed to later.
The Kabini parts (Jaguar + GCN) will be branded Opteron X-series. So far there are two announced products; one utilizes the onboard graphics portion while the other has the GCN based unit disabled. The products have a selectable TDP that ranges from 9 watts to 22 watts. This should allow the vendors to further tailor the chips to their individual solutions.
The X1150 is the GPU-less product with adjustable TDPs ranging from 9 to 17 watts. It is a native quad core product with 2 MB of L2 cache. It can be clocked up to 2 GHz, which we assume is that 17 watts range. The X2150 has an adjustable TDP range from 11 to 22 watts. The four cores can go to a max speed of 1.9 GHz while the GPU can go from 266 MHz up to a max 600 MHz.
