Windows 7 DX11 Cards

News on Nvidia's latest....

Antilles lurking in the shadows
DonanimHaber is reporting that Nvidia will introduce its dual-GPU card at the PAX East 2011 event, which kicks off March 11.

The new card, designated GTX 590, packs two GF110 cores on a single PCB, but we still don’t know the details. It should pack 3072MB of GDDR5 on a double 384-bit bus, but there is no word on the clocks yet. The biggest concern, of course, is power consumption. There’s a good chance the GTX 590 will be the hottest and hungriest card of all time.

AMD is also working on its HD 6990 Antilles board and it should launch at about the same time. It appears neither Nvidia nor AMD will showcase the new boards to the general public at CeBit, but they should show up a couple of weeks later nonetheless.

Geforce 8800GT enough for medium settings

Since Nvidia is one of the main companies behind Crytek and its Crysis 2 game, they had a chance to get it early and test some of its own graphics cards on various settings and resolutions. It looks like optimisation done by Crytek has paid off so you'll be able to play it quite nicely at 1680x1050 and medium settings while running the, now quite old, Geforce 8800GT graphics card.

Nvidia ran the benchmark with 8800GT, GTX 260, 460, 560 Ti, 570 and the 580 paired up with Core i7-960, 6GB of DDR3 memory and Windows 7-64-bit OS. The 8800GT was enough to score just above 30fps at 1680x1050 on medium (Advanced) settings.

Hardcore settings are a different story and if you want to run the game at those settings and at 1920x1200 you'll need the GTX 460 at least. At the same time, the GTX 570 is the cheapest card that can run over 30fps at hardcore settings and at maximum 2560x1600. At 1680x1050 the GTX 260 is quite enough to get you over 30fps at hardcore settings.

You can check out the full test lineup here.

Totally abscent is the Dx10/Dx11 scores... is that suggesting there will be no enhanced dx10/11 support? or indeed the cards performance drops like a lead weight ?

Strange also they didn't include ATI 5870.

would'nt worry, tested the demo on mine in hardcore detail at 1080p and was getting well over 60fps, even with fraps on it still remained decent fps (fraps alone nicks about 25% fps I find) for making my youtube vid... although the motion blur really irritates the hell out of me.

The new king of the hill

The day has finally come and we have the first of the new dual-GPU cards as AMD has finally launched its Radeon HD 6990 dual-GPU card, codename Antilles. The new Radeon HD 6990 features two Cayman GPUs on a single PCB so you end up with a total of 3072 stream processors.

The new Radeon HD 6990 works at 830MHz for the GPUs, has a 2x256-bit memory interface and 4GB of GDDR5 memory clocked at 5000MHz. Once again, AMD decided to include the BIOS switch that takes the card up to 880MHz for the GPUs. According to the AMD spec sheet, the card has a 375W TDP as it needs two 8-pin PCI-E power connectors.

AMD suggests a 750W+ power supply or a 1000W+ one in case you want to run two of these for some CrossfireX action. The backplate features one DVI and four mini DisplayPort outputs. There is nothing to worry about as every single card will ship with adapters for two more DVIs and one HDMI output.

In order to cool down the GPUs, AMD opted for a dual heatsink cooler that is cooled by a single, central blower fan. According to the first reviews, the cooler keeps the card at reasonable temperatures and it doesn't make that much noise. The price, something that hasn't been talked about that much, is set at US $699. If you think that this is a bit steep, however, just bear in mind that we are talking about the performance king.

Cream of the crop from TGT

Point of View / TGT cream of the crop when it comes to graphics cards is finally ready and should roll out to retail/e-tail tomorrow. The POV/TGT GTX 590 Beast will feature slim-line Aquagrafx water block and should easily end up to be the fastest graphics card that money can buy, like POV/TGT GTX 590 Ultra Charged wasn't enough.



The TGT tuning team managed to get this one to ship out working at 691MHz for each of the GPUs, 1382MHz for shaders and 3710 for memory. In case you somehow missed the dual GPU Nvidia Geforce GTX 590 card, it features two GF110 GPUs for a total of 1024 CUDA cores (512 per GPU) slapped on a single PCB with a total of 3072MB of GDDR5 memory paired up with a 2x384-bit memory interface.

These specs didn't stop POV/TGT to raise the clocks from, quite unimpressive, 607/1215/3414MHz to 691/1382/3710MHz on the Beast card. The POV/TGT GTX 590 Beast is paired up with Aqua Computer AquagraFX full-cover copper/nickel-plated water block that keeps the GPU at around 50 degrees C, or around 30 degrees cooler than the air cooling.

The drawback will probably be the price as such card ends up pretty expensive. Currently it is only listed at around €800 depending on the region, but that is what you get when you pair up expensive dual-GPU card with a high-performance water block.

notice the deliberate omission of the 6990 from ati that apparently spanks it

The omission is not deliberate, as the benches were made before 6990.
As you can see in the pictures, ATI 5870CF and ATI 5970 also beat GTX580. So what?

What's remarkable about GTX580 is it's smaller and cooler. Quite expensive of course.

GeForce GTX 590, using two GF100 GPUs after seeing the GeForce GTX 480's obnoxious thermal/electrical figures. GF110 is worlds apart from GF100 in terms of thermal and electrical characteristics, but even that left a bit of a doubt if NVIDIA can actually pull of a dual-GPU graphics card design based on it, let alone a single-PCB dual-GPU design. Well, NVIDIA's engineers shut us up with their GeForce GTX 590. But that's only a part of the story. Whether this 6 Billion transistor, 1024 CUDA core, 3 GB over 384 GB/s monstrosity keeps its cool.

Radeon HD 6990 review

Interesting news....

Soon you will see a new wave of motherboards getting PCIE 3.0 support but well, there's nothing out there utilizing all that extra bandwith and power spec. Well, good news, AMD's next generation of graphics processors (HD 7000 series) reportedly will be PCI-Express Generation 3 compliant. The desktop discrete graphics cards will feature PCI-Express 3.0 x16 bus interfaces, and will be fully backwards-compatible with older versions of the bus, including Gen 1 and Gen 2.
PCIE 3.0 doubles the bandwidth over PCI-E 2.0, with 1 GB/s of bandwidth per lane, per direction. PCI-Express 3.0 x16 would have 32 GB/s (256 Gbps) of bandwidth at its disposal, 16 GB/s per direction

Radeon HD 7000 Series PCI-Express 3.0 Compliant

Softpedia reports that AMD has the 28nm process on track with the 7000 series cards scheduled for later this year:

We also passed several critical milestones in the second quarter as we prepare our next-generation 28-nanometer graphics family,” said Seifert.

“We have working silicon in-house and remain on track to deliver the first members of what we expect will be another industry-leading GPU family to market later this year.

aye that's what I'm waiting on, as I mentioned on yesterday's blog... just upped my PSU in readyness...lol

Wow! Looks like the 28nm node will soon be a reality:

Interim AMD CEO Thomas Seifert revealed that his company already has working samples of GPUs fabricated using a 28nm manufacturing process. AMD also says it is on track to unveil a revamped GPU lineup, codenamed Southen Islands, using the new process later this year.
