AMD has announced their newest GPU , the HD7990.
The HD 7990 combines two GPUs and can deliver 8.2 (peak) TFLOPS single precision, and 2 TFLOPS (peak) double) precision. AMD claims they can run Tomb Raider with their new TressFX Hair technology enabled, or Crysis3 in 4K resolution. However, remember: 4K monitors are currently limited to 30 fps. The HD 7990 comes with 6 GB GDDR5, so it has the memory to double or even triple buffer a 4K display. The HD7990 supports 4K through its DisplayPort ports, and they in turn can generate an HDMI via a dongle cable.
Definitely sounds impressive, and in addition they’ve added a new “Eyefinity 5″ mode perfect for gaming. I’ve recently run into this myself where the Eyefinity setup runs great with 4 or 6 monitors, but 5 seems to be a weird “unknown” set. In this card, 5 monitors create a long 5×1 line of monitors, with the Center of the display in the center of the 3rd monitor.
The card is expected to retail for $999.

AMD is touting their new Radeon HD 6990M as the “world’s fastest notebook GPU” with some interesting slides showing it beating recent NVidia mobile offerings.
Slides from AMD show the chip outperforming both its own Radeon 6970M and NVIDIA Corp.’s (NVDA) GeForce GTX 580M in games like Batman Arkham Asylum, Dragon Age 2, Shogun 2, BattleForge, Left 4 Dead, Metro2033, Wolfenstein MP, The Chronicles of Riddick, and ET: Quake Wars. No independent benchmarks have been released yet, so the validity of these claims depends on how much you’re willing to trust AMD.
The chip will land as an option for Dell Inc.’s (DELL) Alienware M18x and Clevo’s P170HM and P150HM notebooks, both of which also offer the GTX 580M.
The chip offers 1120 SPU’s, 56 Texture units, and an impressive 715Mhz core clock. The memory clock and ROP’s remain unchanged, so there may not be much of a different on anything heavily memory dependent. The new chip will support Eyefinity, but won’t support any type of switchable graphics.

AMD just wrapped up their first Fusion Developer summit (AFDS) where they got indepth into the fusion architecture, talking about GPU computing and its future in modern architectures, and leaked some information about their upcoming design “Graphics Core Next”. Anandtech has all the details.
The fundamental issue moving forward is that VLIW designs are great for graphics; they are not so great for computing. However AMD has for all intents and purposes bet the company on GPU computing – their Fusion initiative isn’t just about putting a decent GPU right on die with a CPU, but then utilizing the radically different design attributes of a GPU to do the computational work that the CPU struggles at. So a GPU design that is great at graphics and poor at computing work simply isn’t sustainable for AMD’s future.
With AMD Graphics Core Next, VLIW is going away in favor of a non-VLIW SIMD design. In principal the two are similar – run lots of things in parallel – but there’s a world of difference in execution. Whereas VLIW is all about extracting instruction level parallelism (ILP), a non-VLIW SIMD is primarily about thread level parallelism (TLP).

We recently told you about how Nvidia was claiming that AMD was cheating on their image quality in order to improve on their performance. The fine folks over at Guru3D have taken a look at dispute, and ask the question: Is it a cheat or a valid optimization if most people cannot tell the difference? Personally, I think ATI should have left the optimization turned off by default.
The optimization can be seen, it really is visible image quality degradation. But here’s the dilemma, it remains difficult to spot if you do not know exactly what you are looking for. Would this question not have been raised then 99.99% of you guys would have never noticed it.

A couple of sites are carrying news about AMD’s newest offerings in the graphics space, the Radeon HD6800 series. Over at EXPreview, they have some details on the upcoming 6870 (shown above) and 6850.
AMD Radeon HD 6870 is based on Barts XT,features 960 stream processors,1GB GDDR5 memory,with memory interface of 256-bit,core/memory frequency of 900MHz/4200MHz,respectively.
AMD Radeon HD 6850 is based on Barts Pro,features 800 stream processors,1GB GDDR5 memory,with memory interface of 256-bit,core/memory frequency of 775MHz/4000MHz,seperately.
And Techspot has a full slide (from Chiphell) showing some of the detailed specs of the 6700 series.
It still seems weird to not be calling them the ATI Radeon’s, but I suppose it had to happen eventually. All the cards looks pretty nice, but I’m sad to see only 1GB of ram on each, and a 256bit bus. They might be great for gaming, but seems they aren’t focusing very heavily on GPGPU with these releases.
AMD is looking to recapture a bit of CAD glory via a new collection of AutoCAD and 3dsMax plugins that look strangely familiar to the old NVidia MAXTreme drivers for the same packages. Using the plugins and a compatible ATI FirePro or FireGL card, you can see some pretty significant performance boosts, as shown above.
ATI’s FirePro application support team have devised a way to drastically increase the performance of FirePro or FireGL workstation graphics cards when running AutoCAD or 3ds Max. AMD has just released a set of performance plug-ins designed to provide additional optimizations for AutoCAD 2010, AutoCAD 2011, 3ds Max 2010, and 3ds Max 2011. With these plug-ins, ATI claims their “FirePro graphics cards offer more than double the performance over comparable consumer graphics cards.” AMD claims users can expect significant improvements in visual quality as well.
It looks like they’re trying to fight back to regain some of the market they’ve lost to Quadro in the high-end workstation space. AMD’s (it still seems unnatural to call them AMD instead of ATI, but I digress) FirePro cards are nice cards, but the custom GL support in Quadro has really crushed them in the workstation benchmarks. Hopefully these new plugins will close the gap.

ATI (or is it AMD?) has just released the first version of their ‘AGS’ library, ATI GPU Services, that provides an API for querying information beyond standard API’s.
This library provides software developers with the ability to query ATI GPU software and hardware state information that is not normally available through standard operating system or graphic APIs. Version 1.0 of the library includes support for querying graphics driver version info, Crossfire (ATI’s multi-GPU rendering technology) configuration info, as well as Eyefinity (ATI’s multi-display rendering technology) configuration info.
Unfortunately, it’s only available for Windows-based platforms right now. ATI’s continued absence of anything on the Linux or OSX side continues to lock them out of the high-end space as more users move away from Windows to more open and secure systems.

Over at Develop3D, they got the scoop on Dassault System’s use of new ATI FirePro V9800 cards that supports the 6-way EyeFinity, and find that it actually works pretty well. I have to admit, I had to wonder if a single card has the necessary horsepower to push 6 monitors with any decent framerate. I’m not the only one.
Of course the practice of using a single graphics card to drive multiple monitors also has its critics. AMD rival Nvidia, who can currently only support two monitors with one of its Quadro graphics cards, says that there is not enough 3D performance in a single card to drive high-res powerwalls effectively.
This is a claim refuted by AMD, who explained that the card is already in use at a number of customer sites and there has been positive feedback. Dassault Systèmes, for example, has been testing Catia V5 and V6 with an ATI FirePro V9800 and has reported that performance is still very good after switching from one to six HD resolution screens.
ATI claims a 10% performance penalty when driving 4 monitors, and an adidtional 10% when driving 6. That seems a bit low to me, as that’s a lot of pixels to push on each frame. However, they may be simply exploiting popular shortcuts, as typically the 2 screens in the center will hold the bulk of the geometry (The user’s natural tendency to put the main focus front and center), with the remaining 4 screens only partially used. In the example shown above, the upper-left and lower-right screens are nearly unused.
Of course, there is also the question of resolution. They say “6 HD screens”, but HD could be 1280×720 or 1920×1080. I run my big screens at 2560×1600, can this run 6 of those in a timely manner? I honestly don’t know.
