According to sources over the web, the upcoming Radeon HD 6970, based on the Cayman GPU, features 1536 scalar processors dispatched in 24 SIMD (64 SP per SIMD, new architecture compared to Radeon HD 5870 which has 80 SP per SIMD), a core clock of 880MHz, 96 texture units and 2GB of GDDR5 memory 256-bit.
Update (2010.12.10): here are the latest speculations from Beyond3D forums:
– HD 6950 (Cayman PRO): 1408 SP (22 SIMD)
– HD 6970 (Cayman XT): 1536 SP (24 SIMD)
The compute power of the HD6970 is 2.7 TFLOPS (like the HD 5870):
In the power consumption side, the HD 6970 has a TDP less than 300W. Actually the HD 6970 will have three levels of power consumption controlled by a new feature called PowerTune:
– Maximum Power
– Typical Gaming Power
– Typical Idle Power
Humm… Typical gaming power I see but maximum power? For FurMark-like apps?
