All of the speculation about the problems TSMC has had with their 28nm process and the possible issues they might have producing enough wafers to meet their clients demands. Today we hear from DigiTimes that Qualcomm is going to switch to Samsung, possibly because TSMC was focusing on AMD and NVIDIA, but this is pure speculation at the moment. What seems more reliable is that GPU vendors are stating that both AMD and NVIDIA are sticking with TSMC which makes a lot of sense, even if TSMC has problems delivering it is a better alternative than AMD or NVIDIA redesigning their graphics processors to be compatible with Samsung's process. The story also mentions that in 2013 Brazos 2.0 and Hondo will be moved to a 28nm design, again likely sourced at TSMC.
"While Qualcomm has reportedly switched foundry orders for its 28nm-based Snapdragon S4 processors from Taiwan Semiconductor Manufacturing Company (TSMC) to Samsung Electronics because TSMC's 28nm capacity has failed to meet its needs, Nvidia and AMD may not follow suit, according to graphics card makers.
TSMC has the upper hand over Samsung in 28nm technology, yield rate and price and therefore changing foundry partnership involves high risks, the sources said. In addition, Nvidia is expected to consider Samsung's ARM-based processors in competition with its Tegra 3 processors, the sources indicated."

Tagged: rumor, hd 7950 GHz edition, graphics card, gpu boost, gpu, amd
An interesting rumor floating around the internet concerns a new AMD 7950 graphics card. Specifically, a forum post over at EXPReview hinted at a new GHz Edition 7950 card. They reference a source and a photo of a graphics card with GHz Edition markings and two six-pin PCI-E power connectors. They further quoted a source that said AMD would be releasing a fourth card to its 7000-series lineup. In other words, there was not a whole lot to go on.
The alleged AMD Radeon HD 7950 GHz Edition graphics card.
I saw the rumor a couple of days ago, but decided to let it sink in for a bit before writing about it. After some thought and internal conversations, I think a 7950 GHz edition is plausible, and certainly a possibility. With the addition of the HD 7970 GHz Edition (which we recently reviewed), AMD now has a 7900 series part with its new GPU Boost (aka Powertune Boost) technology. Unfortunately, that tech can not simply be rolled out to the other existing 7900 series cards meaning that the original 7950 and 7970 are stuck without boost, leaving a gap in its lineup. Because of that, it seems logical that AMD would want to fill in that gap with a refreshed 7950 part that has higher clocks and GPU boost.
The 7970 GHz Edition helped AMD stay competitive with the NVIDIA GeForce GTX 680 and enabled AMD to (re)claim it had the fastest single GPU card. That card was enabled by AMD finding extra headroom and higher bins in its 28nm GPUs. The current Radeon HD 7950 runs at an 800 MHz GPU clock speed and a 5GHz GDDR5 effective clock speed. It is unclear if the company’s chips have enough headroom that they are able to overclock 7950 oriented silicon or if they are simply reworking the bins such that the 7950 GHz Edition is either using silicon that just barely can’t make the cut as a 7970 GHz Edition or AMD is artificially locking down 7970 GHz chips to make these proposed 7950 GHz GPUs. Apart from the increased clock speeds and GPU Boost, the rumored card is said to maintain the same hardware specifications as the existing 7950. Mainly, that means 1,792 stream processors, 112 texture units, and the same number of transistors – 4.31 billion – on a 28nm process. In comparison, the 7970 has 2,048 stream processors and 128 texture units.
As mentioned above, such a chip sounds like a logical step for AMD. By refreshing the 7950 with higher clock speeds and adding GPU Boost functionality it will be fight with the GeForce 670 for the performance crown, and may even come close to 680/7970 performance when overclocked further. I do have a couple of questions about this rumored card, however. Specifically, I am wondering if AMD will simply refresh the 7900 series cards and let the original releases fade out as the stock dwindles or if they will keep them around. I’m leaning towards the later but it will still be interesting to see, and it also makes me wonder how much a 7950 GHz Edition will cost me.
I’m curious what you think about the rumor though, do you think it has any merit? And assuming this is legit, where do you think it will stand performance-wise versus NVIDIA’s products?
If you are curious about how AMD’s new GPU Boost technology works, be sure to check out our Live Review of the Radeon HD 7970 GHz Edition with AMD’s Evan Groenke where we are given a live demonstration showing how it works and some background on the technology.
Less Risk, Faster Product Development and Introduction
There have been quite a few articles lately about the upcoming Bulldozer refresh from AMD, but a lot of the information that they have posted is not new. I have put together a few things that seem to have escaped a lot of these articles, and shine a light on what I consider the most important aspects of these upcoming releases. The positive thing that most of these articles have achieved is increasing interest in AMD’s upcoming products, and what they might do for that company and the industry in general.
The original FX-8150 hopefully will only be a slightly embarrasing memory for AMD come Q3/Q4 of this year.
The current Bulldozer architecture that powers the AMD FX series of processors is not exactly an optimal solution. It works, and seems to do fine, but it does not surpass the performance of the previous generation Phenom II X6 series of chips in any meaningful way. Let us not mention how it compares to Intel’s Sandy Bridge and Ivy Bridge products. It is not that the design is inherently flawed or bad, but rather that it was a unique avenue of thought that was not completely optimized. The train of thought is that AMD seems to have given up on the high single threaded performance that Intel has excelled at for some time. Instead they are going for good single threaded performance, and outstanding multi-threaded performance. To achieve this they had to rethink how to essentially make the processor as wide as possible, keep the die size and TDP down to reasonable sizes, and still achieve a decent amount of performance in single threaded applications.
Bulldozer was meant to address this idea, and its success is debatable. The processor works, it shows up as an eight logical core processor, and it seems to scale well with multi-threading. The problem, as stated before, is that it does not perform like a next generation part. In fact, it is often compared to Intel’s Prescott, which was a larger chip on a smaller process than the previous Northwood processor, but did not outperform the earlier part in any meaningful way (except in heat production). The difference between Intel and AMD in this aspect is that as compared to Prescott, Bulldozer as an entirely new architecture as compared to the Prescott/Northwood lineage. AMD has radically changed the way it designs processors. Taking some lessons from the graphics arm of the company and their successful Radeon brand, AMD is applying that train of thought to processors.

Gigabyte has had an overclocked version of the Radeon HD 7770 graphics card for a couple months now, but the company is already readying a second revision of the card. Curiously, the new revision will maintain the same hardware but will run at slightly lower clock speeds. While the current revision (1.0) runs at 1100 MHz and 5000 MHz for the GPU core and memory respectively, the updated graphics card will run at 1050 MHz and 4500 MHz.
Beyond the lower clock speeds, the new revision of the GV-R7770 OC card maintains the same PCB, chips, and cooler design. That hardware includes a 28nm GPU, 1GB of GDDR5 memory on a 128-bit interface, and a PCI-E 3.0 expansion slot. Display outputs include a DVI port, full-size HDMI port, and two mini DisplayPorts. It also maintains the same custom Gigabyte heatsink and fan.
According to Videocardz, users will be able to identify which revision they are getting before handing over any money by looking at the box. Alternatively, users can identify which revision it is by looking at the sticker on the underside of the card just above the PCI-E connector. As a new revision, especially with the release of higher-binning chips from AMD, it is a bit confusing that the card is being released with lower clock speeds than its predecessor. It may be that the higher factory overclock was not stable on enough cards and Gigabyte was having to deal with too many returns – that’s only a guess though.
All the same, if you are shopping for a 7770 graphics card and have been considering the Gigabyte model, be sure to double check which revision you are getting.

Tagged: low power, geode, G-T16R, embedded, amd
The new embedded processor from AMD replaces the old Geode series and brings new performance to the ultra low end as this is a 4.5W TPD processor. The G-T16R APU supports Windows 7 Embedded Compact 7, Green Hills Integrity and Express Logic Thread X operating systems which makes the lack of support for DirectX 11 a moot point as these OSes are not about to need that support to begin with. The ultra low TDP means that no fan is required to use this processor and so you can expect an average draw of 2.3W from the system.
DirectX 11 might be missing but looking below you can see that there is a lot of other features included with this chip, from SATA 6Gbps to HD audio as well as HDMI out and support for PCIe 2.0 4x cards, you can get quite a bit from this little chip. Check out the ASUS press release here or just read the summary available at The Inquirer.
"CHIP DESIGNER AMD launched its lowest power accelerator processing unit (APU) yet with the 4.5W TDP G-T16R.
AMD's G series embedded GPUs have been offering some of the lowest power DirectX 11 capable chips for some time and now the firm has brought the TDP down even further with the G-T16R. Although the G-T16R doesn't support DirectX 11, it claims considerable performance benefits over the almost archaic but popular Geode LX embedded processors."

Well, we did it! Today I successfully built an AMD A-series APU based computer while blindfolded LIVE. At the start of the event I went over the various components used for the build including the AMD A8-3800 APU, MSI A75 motherboard, Corsair 550D case and 650 watt power supply and more. After showing it all, I wrapped a scarf around my head and went to work.
There were quite a few more hurdles than I expected including spreading the thermal paste correctly, screwing the motherboard into the case and finding the pins for the front panel power button. I was surprised at how easily I was able to install the APU, memory and heatsink, but that likely comes with years of practice and experience with the hardware.
In all, it took me 1 hour and 18 minutes to get to a Windows screen using a pre-installed OS on a Western Digital 1TB hard drive. That was MUCH longer than I had originally thought it would take, so I have been humbled by those DIY PC users that build their own on without sight a regular basis!
If you missed the live event we hosted at http://pcper.com/live you can find the replay hosted right here below. Enjoy watching me completely make a fool of myself!
Update: The winner of the blindfolded system was selected, congrats goes to Darren who gets the task of rebuilding this rig! :D

Tagged: tahiti, gpu, ASUS ROG, asus, amd, 7970
ASUS recently posted a few teaser photos of its upcoming Republic of Gamers branded 7970 graphics card. The Matrix HD 7970 is a three slot design with the company’s DirectCU II heatsink, dual fans, DIGI+ VRM, and (of course) AMD’s 7970 Tahiti GPU core. While likely not based on the higher-binned cores used in the new 7970 GHz Edition graphics cards, with the large cooler and extra power phases that ASUS is packing into this Matrix GPU it should overclock to similar levels of performance.
The card features fans, and a large dual slot cooler with the traditional red and black ROG theme. The ASUS and Matrix logos are etched into the side of the card as well. The PCB is black and further covered by a bracing plate to reinforce the PCB to support the weight of the cooler. On the front of the card, it houses an air vent, two DVI connectors, and four DisplayPort video outputs. On the back of the card are four buttons. Two of the buttons with plus and minus symbols let you adjust the core voltage in preset jumps. The Safe Mode button next to the minus button clears the overclocks from the BIOS and resets the card to default settings. Finally, the red button will spin the fan up to 100% to overclock the card as far as possible. They also have a bank of LEDs below the buttons that offer at-a-glance load monitoring (really only useful for those testing outside a case...). In the rear corner of the card is two eight pin PCI-E power connectors. Then, on the underside (top when installed in the case) of the graphics card’s PCB, ASUS has a VGA Hotwire port which allows the card to interface with the ASUS OC Key and Extreme edition motherboards (such as the Maximus V and Rampage IV Extreme). There are also voltage checking points.
Internals are somewhat similar to ASUS Radeon HD 7970 DirectCU II, but with some aspects ratcheted up. The power phases, for example, have increased from 12 phases to 20 on the Matrix card. It continues to use the 7970 “Tahiti” GPU with 2048 shaders, 32 ROPs, and AMD’s Graphics Core Next architecture. ASUS is packing 3GB of GDDR5 memory with a 384-bit memory interface. ASUS has stated that both the GPU core and memory will be overclocked from the factory. Unfortunately, they have not released any specific numbers. We will have to wait until the card is closer to the launch date for that information.
The ASUS ROG Matrix graphics card will be launching in Q3 of 2012. It will be aimed at extreme overclockers – especially those that are already using Republic of Gamers branded motherboards from ASUS. What do you think of this new card, especially now that AMD has launched its 7970 GHz Edition reference GPU? You can find more photos of the card over at the ASUS website.

Of course, we were not the only ones to review the card that represents AMD's attempt to win back the single GPU performance crown from NVIDIA. [H]ard|OCP also examined the updated HD7970, which should be available fairly soon for a price of $500. The GHz Edition is slightly faster than the original, with a 1000MHz base clock and 1050MHz Boost Clock, and an effective memory speed of 6GHz, though the power consumption should not change much. It did start pulling a bit more power once [H] had overclocked it to 1180MHz and 6.4GHz for the memory, but even with AMD's GPU Boost it looks like NVIDIA still reigns ... though with less of a lead than before.
"We have been documenting AMD's struggle to compete with the NVIDIA Kepler generation since it was introduced. Today AMD attempts to strike back with the Radeon HD 7970 GHz Edition. This video card features higher operating speeds and introduces AMD's version of GPU Boost. Will the performance justify a price of $499?"
