HardOCP check out the Sapphire HD 7970 OC Edition Video Card and brings promises of low temperatures with Sapphires Dual-X Cooling System:
Read the review here.The Radeon HD 7970 GPU itself is comprised of 4.32 billion transistors packed into 2048 stream processors with a clock speed of 925MHz. There are 128 texture units, 128 Z/stencil units, and 32 ROPs. That is a 33% increase in stream processors and texture units compared to the Radeon HD 6970, but the same number of ROP. Even so, optimizations and clock speed increases should result in more efficient rasterization.
The Radeon HD 7970 is designed to be paired with 3GB of GDDR5 memory on a 384-bit bus, running at 1375MHz for a 5.5Gbps data rate and a maximum theoretical bandwidth of 264GB per second. In spite of its increased capacity and its performance improvements, the Radeon HD 7970 shares the same 250W maximum board power rating as the HD 6970.
