AMD Cayman, Antilles Specifications Surface
At last, specifications of AMD's elusive Radeon HD 6970 and Radeon HD 6990 graphics accelerators made it to the internet, with slides exposing details such as stream processor count. The Radeon HD 6970 is based on a new 40 nm GPU by AMD, codenamed "Cayman". The dual-GPU accelerator being designed using two Cayman GPUs is codenamed "Antilles", and carries the product name Radeon HD 6990.
Cayman packs 1920 stream processors, spread across 30 SIMD engines, indicating the 4D stream processor architecture, generating single-precision computational power of 3 TFLOPs. It packs 96 TMUs, 128 Z/Stencil ROPs, and 32 color ROPs. Its memory bandwidth of 160 GB/s indicates that it uses a 256-bit wide GDDR5 memory interface. The memory amount, however, seems to have been doubled to 2 GB on the Radeon HD 6970. Antilles uses two of these Cayman GPUs, combined computational power of 6 TFLOPs, a total of 3840 stream processors, total memory bandwidth of 307.2 GB/s, a total of 4 GB of memory, load and idle board power ratings at 300W and 30W, respectively.

I guess the reviews on launch day will be the decider in what i have to do.
I'm going to have to put some more thought into this.
I plan on getting a beast of a rig eventually bear, but it won't be in December, I'm getting like £400 at the start of the month : / not enough for fancy rigs :laugh:
Next year though I'ma grab a few bits and bobs : ] ( 6970 or wailt til q2 and get 7000 series and bulldozer)
Looking at an AMD set up ( assuming their still best bang for buck)
I'm pretty sure i have kicked it's resale value right in the nuts :roll:
Don't get paid til the 6th though.
With a bit of planning i should easily afford a 6970 and either a normal SSD or even a revodrive x2 :D before the end of the year but i suppose just the 6970 would keep me happy for now.
