Team Katana Japan Sets 3DMark 11 Extreme Record with 1747/7884 MHz @ 1.895V HD 7970
Like UnlikeFiled in: Graphic CardsAMDRadeon HD 7970
Team Katana Japan set a new 3DMark 11 Extreme Preset single-GPU world record using their Radeon HD 7970 graphics card clocked at staggering clock speeds 1747 MHz (core) and 1971 MHz or 7.884 GHz effective (memory). These clock speeds were sustained using volt-modding (to maintain the right voltage stable), and liquid nitrogen cooling. The volt-mod was designed to override the OCP (over-current protection), and over-heat protection of the graphics card's VRM. The target core voltage was 1.895V.
The setup went on to bag a 3DMark 11 Extreme Preset single-GPU world record, where it scored X3757.69 points, bagging 1st Rank in HWBOT's "GLOBAL 1X GPU RANK" and "Radeon HD 7970 rank". Find the valida...

Maingear says it will offer the AMD Radeon HD 7970 in its Shift, F131 and Vybe desktops
Like UnlikeFiled in: Desktop ComputersGraphic CardsAMDMAINGEARSHIFTF131VYBERadeon HD 7970
When AMD announced its latest flagship, the Radeon HD 7970, we knew it was fast and efficient (because reviewers said so!), but gamers were told they'd have to wait until the new year to try it themselves. Now, precisely on schedule, the card is available for purchase, and we're starting to hear word of systems that will be refreshed to include the 28nm card. Maingear just said that it will offer the 7970 inside its Shift and F131 desktops, followed by the Vybe at some later date. If you recall, the card has a 925MHz engine that can be overclocked to 1.1GHz, 2,048 stream processors and an unusual 384-bit memory bus serving 3GB of GDDR5 -- not to mention, it's capable of a mere 3W power draw ...

Four Radeon HD 7970s cooled with liquid nitrogen en route to crazy benchmark scores
Like UnlikeFiled in: Graphic CardsAMDRadeon HD 7970
What do you get when you take four of the fastest single-GPU graphics cards on the market, add a little liquid nitrogen, connect them to two 1,200W power supplies, and crank them to 1.6GHz each? The answer is Andre's monstrous "quad seventy-nine seventy" rig, pictured above. The AMD Radeon HD 7970 cards already feature an impressive clock speed of 925 MHz, and while AMD has said they can be pushed safely over 1GHz, overclocking them by almost 75 percent will get you some truly staggering benchmark performance.

AMD denies hidden cores in Radeon HD 7970
Like UnlikeFiled in: Graphic CardsAMDRadeon HD 7970
A leaked Sapphire document revealed a Tahiti GPU with 2304 cores. AMD however confirms that there are no hidden cores. The chip has 2048 shaders, so the 2304 number from Sapphire is likely a mistake, or part of a test by AMD to find out which partners leak specifications to members of the press.

HD 7970 Overclocked to 1.26 GHz: 28 nm Tech Really Stretches Its Legs
Like UnlikeFiled in: Graphic CardsAMDRadeon HD 7970
It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest – excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.
