Although the leaks that occurred over the past few weeks and months have provided us with plenty of information regarding what we could (and should) expect from AMD's Cayman-based graphics cards, the day when AMD officially releases its next-gen Radeon HD 6900 series GPUs has finally arrived.
So, today, the company took the wrapps off its first two HD 6900 models, the flagship Radeon HD 6970 and the Radeon HD 6950, which will soon be pitted against their rivals from NVIDIA in an epic struggle for the consumers' attention (and cash).
The Radeon HD 6970 delivers 2.7 TFLOPs (IEEE754-SP)/675 GFLOPs (IEEE754-DP) of compute power, featuring a Core Clock Speed of 880MHz, 24 SIMD / 1536 ALU Stream Processors, 96 texture units, 32 ROPs and 128 Z-Stencils, 2GB GDDR5 memory on a 256 bit and 5.5 Gbps bandwidth, while the board power is rated below 300W.
The AMD Radeon HD 6950, on the other hand, delivers 2.25 TFLOPs (IEEE754-SP)/563 GFLOPs (IEEE754-DP) of computer power with the help of its Core clocked at 800MHz, as well as its 22 SIMD / 1408 ALU stream processors.
The second 6900 series Radeon also features 88 texture units, the same ROPs / Z-Stencil figures as the its more powerful sibling, as well as the same amoung of memory (although the bandwidth is slightly smaller, just 5 Gbps), but a lower power consumption (TDP under 225W).
After checking out the tech specs, we'll also have to mention that, theoretically, the HD 6970 is 15 percent faster than the 580 and the 6950 is 20 percent faster than the 470, but no comparative data involving the 500 series from NVIDIA has been provided.
