Will the AMD RV790 Architecture be Something Different? - 03/09/09 07:28 AM
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.

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!!
