AMD Radeon HD 7970 3GB GDDR5 PCIe
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.

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.
