Radeon HD 6970 runs at 880MHz

Written by Fuad Abazovic

1536 ALU stream processors

We got some official data about AMD's Radeon HD 6970 card codenamed Cayman XT. The card runs at 880MHz and the card has the memory that runs at quite impressive 5.5GBps. The memory of choice is GDDR5 in 256-bit flavour and the card has 2GB of it.

The card has 96 texture units, as well as 24 SIMD and 1536 ALU streaming processors. It has 32 ROPs and 128 Z stencils.

Cayman Radeon HD 6970 uses VLIW4  Shader Architecture something that Bobo explain in details here. We can confirm this story today.

Total compute power of Cayman in this version is 2.7 TeraFlops under IEEE754-SP standard and 675 GigaFlops with IEEE754-DP standard.

It is unknown if the card is slower of faster than the GTX 580 but this given presentation didn't really look into it. The indication is that Cayman won't be faster than GF110 products, but in this presentation, ATI didn't show any Radeon HD 6970 performance data.

1536 ALU stream processors for the 6950 not 6970 ;)
Fuade neljuti djece bratee xD

Two days ago 6970 costed 450 DOLLARS, today its alleged at 500 EUROS!

Let us know what is speculation and what is not.

The only thing that is definite in your article is the 2GB memory and VLIW4 shader layout.

OMG,OMG, I need my Radeon fix - ATI is da bomb!!! AMD rules, go radeon, go!!!! When it arrives, my 6970 will be having sexy time, 500% more than GTX480!!!!!

Something is not quite right...
The 5870 has 2.7TF of computing power as well.

you know gtx480 has what 1.4tflops? and its better than 5870...

It means Fuad is fool. Was it just yesterday he posted that HD6970 is 10-20% faster than GTX480 which would put it a bit slower than GTX580. Now he's not sure anymore. If it's slower, then he'd rejoice with half a dozen nasty articles about it :-x

Maybe because the GTX 480 has more geometric throughput?
Fermi actually has 1/2 double precision performance of single precision but they cripple it to 1/8th to sell more Teslas.
