Will the AMD RV790 Architecture be Something Different?

[news 28]

Initial rumors had the RV790 pegged as a speed optimized RV770, which

currently powers the Radeon HD 4800 series of cards. Recent information has

hinted that there is far more than a simple speed increase, and AMD could be

catching us unawares with a potentially exciting new part. I take a look at

AMD's releases over the past two years and make a few guesses as to what we

might expect to see.

Quote: "I do not think we will see a massive increase in stream units as we

saw going from the RV670 to the RV770. I think we will see an increase to

960 stream units (divided into 12 SIMDs), but the amount of RBEs will likely

be unchanged (though AMD would include another texture unit per SIMD, adding

another RBE would sort of upset the orthoganality of the setup).

Considering the current texturing and AA performance of the HD 4870, those

changes are likely not needed in the new chip. Performance increases in

pure pixel fillrate and texturing will be improved from the clockspeed

increases as well as further internal optimizations into these units."

 

Thanks for a post!!
