The AMD ATI Radeon HD 7970 measures 27 cm long (10.6 in), the GPU core is clocked at 925MHz, and the GDDR5 memory operates at the same frequency of 1375MHz (5.5GHz DDR). Still, pairing that frequency with a 384-bit memory bus gives the HD 7970 264GB/s of theoretical bandwidth. The HD 7970 carries 2048 SPUs, 128 TAUs and 32 ROPs, up 33% from 1536 SPUs and 96 TAUs, it's also the first PCI Express 3.0-compatible card.
Fastest single-GPU graphics card we’ve tested to date.
Significantly faster than Nvidia’s GeForce GTX 580, especially at extreme resolutions.
Improved power savings when idle.
Support for 4K video and other forward-looking features.
Brand-new design suited for graphics and compute.
Fastest single-GPU card around.
Strong power-draw credentials.
Best-in-class video performance.
Native full size HDMI & DisplayPort output.
3 GB of memory.
Adds support for PCIExpress 3.0 and DirectX 11.1.
Support for multiple independent audio streams.
4K video content and TVs likely won’t be common for a year or more.
Performance advantage edges off at highest resolutions.
Requires two PCIe power connectors.
Blocks a second expansion slot.
Noisy in 3D.
CCC Overdrive limits too low.
PowerTune and ZeroCore may complicate advanced overclocking.

For the last 12 months, AMD has had the Radeon HD 6970 be its premier single GPU graphics card, competing head to head with the GeForce GTX 570 and at times challenging the mighty GTX 580. For about $369 today, you can still get one hell of a graphics...

Whichever your preference of graphics card manufacturer, whether you sit with the green team or the red, both factions will serve you extremely well. If I were forced to choose between the two as a single graphics card, the KFA2 GTX680 wins out. It...

Obviously when testing a set up this extreme the conclusion is pretty academic.No-one in their right mind would run Quadfire. It takes too much power, we needed two Corsair AX1200 PSUs for this test. It produces too much heat. It's stupidly...

With the last generation of video cards from AMD and NVIDIA, a lot of people felt a bit hard done by. Sure, the GTX 480 to GTX 580 and HD 5970 to HD 6970 brought with it some nice performance gains, but there wasn't the technological leap that we...
