Will the AMD RV790 Architecture be Something Different?
Posted by newsbot on March 09th 2009



I do not think we will see a massive increase in stream units as wesaw going from the RV670 to the RV770. I think we will see an increase to960 stream units (divided into 12 SIMDs), but the amount of RBEs will likelybe unchanged (though AMD would include another texture unit per SIMD, addinganother RBE would sort of upset the orthoganality of the setup).Considering the current texturing and AA performance of the HD 4870, thosechanges are likely not needed in the new chip. Performance increases inpure pixel fillrate and texturing will be improved from the clockspeedincreases as well as further internal optimizations into these units.
