The frame pacing issue has been covered at our website for almost a year now. It stems from the original "microstutter" problem which dates back over a year before we could quantify it. We like to use the term "Frame Rating" to denote the testing methodology we now use for our GPU tests.
AMD fared worse at these tests than NVIDIA (although even they had some problems in certain configurations). They have dedicated a lot of man-hours to the problem resulting in a driver updates for certain scenarios. Crossfire while utilizing Eyefinity or 4K MST was one area they did not focus on. The issue has been addressed in Hawaii and AMD asserted that previous cards will get a software fix soon.
The good news is that we have just received word from AMD that they plan on releasing a beta driver for Southern Islands and earlier GPUs (AMD believes it should work for anything that's not "legacy"). As usual, until it ships anything could change, but it looks good for now.
The beta "frame pacing" driver addressing Crossfire with 4K and Eyefinity, for supported HD-series and Southern Islands-based Rx cards, is expected to be public sometime in January.

Tagged: southern islands, Solar System, Sea Islands, radeon, oland, mars, holycrapiamtotallyconfused, amd
Remember that story we posted last week and then discussed on the podcast about AMD not releasing any new GPUs in 2013? Today we had a call with AMD that attempted to answer some questions, clear up some confusion and give us some insight to the company's direction. I say 'attempted' because after a 53 minute discussion, we have some answers, but we also have some interesting questions that remain.
First, some definitions. If you have heard about code names like "Solar System" and "Sea Islands" you might not know what they refer to. Sea Islands is a new line that will fall into the 8000-series of products and will be a refresh, slightly different architecture based heavily on the Southern Islands parts you've come to love in the Radeon HD 7000 parts. Solar System is the name AMD has given to the sub-category of Sea Islands directly related to mobile products, the 8000M.
The slide that started this confusion - and our questions.
What might make things even more confusing is that there are some 8000-series parts that are already shipping in OEM desktops and notebooks that use verbatim HD 7000 GPU specs. So what you have is a combination series with Radeon HD 8000 that is made up of some rebrands and at least a couple of "new" chips thus far. Those two new GPUs, Mars and Oland (Radeon HD 8650 and HD 8670) depending on the mobile or desktop target, are already out and you can find them if you look hard. They are NOT available in the channel or for DIY PC users.
Our readers might be disappointed to learn that Sea Islands is heavily focused on the notebook and mobile markets though AMD did indicate that there some good things coming for the channel users in the future in 2013.
We also learned that the HD 7900-series will remain the company's high end parts through the end of 2013 but AMD said that there are new SKUs set to be released in this series sometime this year as well. Will that be the elusive HD 7990 dual-GPU product or maybe just something in the mainstream 7800 segments? They wouldn't tell us but we are definitely hoping for higher performance parts. You might also expect to see these new 7000-series parts to use Sea Islands silicon...
The Radeon HD 7970 looks like it will stay a focus for AMD throughout 2013.
Many readers might be wondering why AMD is breaking its standard cadence of near-yearly GPU releases. The answer came from AMD's Roy Taylor, VP of Channel Sales, who said that "7000 series parts are continuing to ramp UP, sales are increasing" so it is premature for AMD, as a company intending to make money, to introduce a new series or architecture.
In fact Roy was very emphatic about relieving us of potential ambiguity.
We have products, we have a road map. We are not announcing them now because we want to reposition the ones we have now. We are not sitting still, we do not lack resources, we do not lack imagination.
So what can you expect for the future? Sea Islands chips will continue to be released and eventually in the desktop, channel market and some of them will be branded as 7000-series parts and some of them will be branded as 8000-series parts. They wouldn't give us information on whether or not you'll see BIGGER chips (which we would assume would be faster) than the current HD 7900 cards or if they would all be in the mainstream segment.
AMD thinks its partnerships with key games like Crysis 3 will help keep momentum in 2013.
The residual message from this call was that AMD wants everyone to know that they have the best products on the market today and to maintain that momentum, AMD will enhance drivers, establish big partnerships with gaming companies and developers and release SOME new GPUs.
AMD was cagey again when asked about the possibility of a new architecture by the end of 2013 but based on the reactions of AMD reps I tend to believe we will see it, though probably very very close to the end of that time. (Update: AMD did in fact say that an entire new product stack would be releaed by the end of 2013.)
That all clear now?

Tagged: southern islands, sony, ps4, playstation 4, orbis, Kaveri, bulldozer, APU, amd
Earlier today a report from Kotaku.com posted some details about the upcoming PlayStation console, code named Orbis and sometimes just called the PS4. Kotaku author Luke Plunkett got the information from a 90 page PDF that details the development kit so the information is likely pretty accurate if incomplete. It discusses a new controller and a completely new accounts system but I was mostly interested in the hardware details given.
We'll begin with the specs. And before we go any further, know that these are current specs for a PS4 development kit, not the final retail console itself. So while the general gist of the things you see here may be similar to what makes it into the actual commercial hardware, there's every chance some—if not all of it—changes, if only slightly.
This is key to keep in mind because here are the specs listed on the report:
- 8GB of system memory
- 2.2GB of graphics memory
- 4 module (8 core) AMD Bulldozer CPU
- AMD "R10xx" based GPU
- 4x USB 3.0 ports and 2x Ethernet connections
- Blu-ray drive
- 160GB HDD
- HDMI and optical audio output
We are essentially talking about an AMD FX-series processor with a Southern Islands based discrete card and I am nearly 100% sure that this will not match the configuration of the shipping system. Think about it - would a console developer really want to have a processor that can draw more than 100 watts inside its box in addition to a discrete GPU? I doubt it.
Instead, let's go with the idea that this developer kit is simply meant to emulate some final specifications. More than likely we are looking at an APU solution that combines Bulldozer or Steamroller cores along with GCN-based GPU SIMD arrays. The most likely candidate is Kaveri, a 28nm based product that meets both of those requirements. Josh recently discussed the future with Kaveri in a post during CES, worth checking out. AMD has told us several times that Kaveri should be able to hit the 1.0 TFLOPs level of performance and if we compare to the current discrete GPUs would enable graphics performance similar to that of an under-clocked Radeon HD 7770.
There is some room for doubt though - Kaveri isn't supposed to be out until "late Q4" though its possible that the PS4 will be the first customer. It is also possible that AMD is making a specific discrete GPU for implementation on the PS4 based on the GCN architecture that would be faster than the graphics performance expected on the Kaveri APU.
When speaking with our own Josh Walrath on this rumor, he tended to think that Sony and AMD would not use an APU but would rather combine a separate CPU and GPU on a single substrate, allowing for better yields than a combined APU part. In order to make up for the slower memory controller interface (on substrate is not as fast as on-die) AMD might again utilize backside cache, just like the one used on the Xbox 360 today. With process technology improvements its not unthinkable to see that jump to 30 or 40MB of cache.
With the debate of a 2013 or 2014 release still up in the air, there is plenty of time for this to change still but we will likely know for sure after our next trip to Taipei.

PowerColor ignored the claims that there would be no dual GPU HD 7990 and created the DEVIL13, with two southern island GPUs on a single PCB. Both GPUs run at the standard HD 7970 speed of 925MHz, with a button to overclock them to 1000MHz and ups the amount of voltage provided to the cores as well, the 6GB of RAM run at the stock 5.5GHz effective. Seeing three 8pin PCIe power connectors is impressive, as is the 3 slot card its self. [H]ard|OCP overclocked the card to a stable 1125MHz GPUs and 6.3GHz memory which put its performance noticeably above that of the SLI'd GTX 680 that they compared this card to. The question remains, if you can get the exact same performance from two overclocked Powercolor HD 7970s for $860 then why spend $1000 on the hard to find DEVIL13?
"PowerColor has beaten AMD to the punch with its own creation of a dual-GPU Radeon HD 7970 CrossFireX solution in a single video card package. We evaluate this awe inspiring video card and of course overclock it to its highest potential. We put it up against the best GTX 680 SLI solution also overclocked, all with the latest drivers."

Enthusiasts were offered a bit of hope this morning with news from DigiTimes that more capacity at TSMC will be available for AMD and NVIDIA which would mean more dies being made and hopefully a larger supply of GPUs. Since TSMC seems to have finished playing with their Cortex A9 process, there is a good possibility that the GTX680 and perhaps even the GTX690 will become common enough that the great unwashed actually have a chance to purchase one. We can also hope that it will give NVIDIA a chance to build up stocks of the GTX670 and 610 which are due out at the end of the month and June, respectively. Unfortunately, if a certain site is correct that may not be the case as NVIDIA will be redoing their mask and not be able to take advantage of the extra capacity TSMC could make available for them. Perhaps if this scenario is true AMD will be able to leverage TSMC to flood the market with Southern Island GPUs and hope to win the availability war as the performance crown is firmly on NVIDIA's head in this generation of GPUs.
"AMD and Nvidia, impacted by Taiwan Semiconductor Manufacturing Company's (TSMC's) fully-booked capacity, had rather weak shipment performance in the first quarter; however, as more capacity will be gradually released by TSMC, shortages of 28nm graphics cards are expected to improve in late May, according to sources from graphics card makers."

AMD, for a limited time and while supplies last, will bundle three games with the purchase of a Radeon HD 7900 Series graphics card. The qualifying cards, the Radeon HD 7950 (now $399) and 7970 (now $479), will be bundled with DiRT Showdown, Nexuiz, and Deus Ex: Human Revolution with The Missing Link DLC.
Getting a game bundled with your GPU is not the most unheard-of practice, but could still be a good deal regardless. Bundling three high-profile games and an expansion DLC for one of them is very likely to be a good deal however you look at it.
AMD will soon launch their “Three for Free” promotion for qualifying Radeon HD 7950 and 7970 video cards from participating resellers. With this program, AMD will throw in DiRT Showdown, Nexuiz, and Deus Ex: Human Revolution with The Missing Link DLC with their video card.
AMD’s throwing DiRT in a Showdown?
The selection of games is quite impressive but they only serve as BBQ sauce for the promotion: the HD 7000 series are receiving price cuts.
AMD is lowering the price of the Radeon HD 7970 to $479 and the HD 7950 to $399 along with the three-and-a-bit free games. Also cut in price, although not qualifying for the free games, is the Radeon HD7770 which loses $20 off of its price tag with an expected price of $139. Check out Ryan’s review for the performance of that card.
You can keep a lookout for these updated prices here on Newegg.com!

TSMC's 28nm process has been in the news for a long time, sometimes this was a good thing but more often it was not. Back in May of 2009 the first announcements of TSMC's brand new 28nm process hit the news with major production slated to start in early 2010. That didn't happen on time, much to several companies dismay as Josh unhappily discussed towards the end of 2010. This set a trend for TSMC's 28nm process for a while, for instance AMD did not quite meet their promise of readily available 28nm GPUs in 2011, though a late December launch for the HD7970 did meet the spirit of the agreement. The delays and issues on TSMC's 28nm lines had a variety of causes, perhaps one of the worst being TSMC's overly optimistic attitude about their production capabilities especially when AMD had a surprise for them. Add to that the long line of woes during the development and production of NVIDIA's 28nm Kepler GPU as well as the recent shutdown of the production line, and you can see why TSMC's 28nm process has spent a lot of time being maligned in the news. It almost makes you forget about the 40nm process woes, but that is ancient news.
All that effort is not going to waste as DigiTimes reports that TSMC is planning on expanding their 28nm capacity this year and expects that process to account for 10% of their 2012 revenue. The next question on most peoples minds is the progress on TSMC's 22nm process which in 2010 they announced would be ready by Q3 2012, something which NVIDIA's Maxwell team is probably anticipating with great anxiety.
"With current capacity for 28nm processes filled up, Taiwan Semiconductor Manufacturing Company (TSMC) is likely to expand the leading-edge process capacity later in 2012, according to industry sources.
TSMC reportedly is running at full capacity at its 12-inch fabs due to strong orders for 28nm as well as 40nm and 65nm designs. In order to avoid orders to rivals such as United Microelectronics (UMC) and Samsung Electronics, TSMC will have to speed up the pace of its leading-edge capacity expansion in particular its 28nm capacity, the sources said."

After a delay of several weeks AMD has finally released a hot fix for Linux to allow for the usage of their new generation of video cards but they've not provided updates that can be rolled into the Linux kernel DRM driver, the X.Org DDX driver, or the new Gallium3D driver. However, since the new features seem to have been enabled with this hot fix, Phoronix picked up an XFX Radeon HD 7950 Black 3GB to test for performance on Ubuntu 12.04 LTS. The good news is that they saw 40~50%+ faster performance than an HD6950 but unfortunately not at stock speeds, the driver did not fully recognize the card and would not let them set the GPU and memory speeds to their full defaults.
"The Radeon HD 7900 series were announced at the end of 2011 and since then the Linux support status for this hardware has remained a big question. For the Radeon HD 7000 series "Southern Islands" GPU launch, they did not send over any hardware samples so Linux consumers have left to be confused over the state of the non-Windows support for AMD's hardware based on the "Graphics Core Next" architecture. Fortunately, here is finally an extensive look at the Radeon HD 7000 series on Linux with testing of a Radeon HD 7950."

To give the end of the story away at the beginning, sometime around March 19th you should be able to find an HD 7870 for about $350 and an HD 7850 for around $250. The HD 7870 not only costs less than the 6970 it consumes less power and can outperform it, making the HD 7870 the more attractive of the two cards. [H]ard|OCP was less impressed with the HD7850 as it costs about $40 more than a GTX 560 Ti but only performs a small amount better. It does consume a lot less power than the NVIDIA card though, which can be a big deal for some users and hints at possible overclocking potential.
Ryan had a slightly better experience with the HD 7850, which might attract those who cannot justify spending over $300 on a graphics card but still want multi-monitor functionality.
"AMD is introducing the performance mainstream Radeon HD 7870 and Radeon HD 7850 today. We'll look at performance compared to the competition and talk about pricing and explore value. If you are in the market for a video card between $249 and $349 these video cards will likely need to be on your short list."
