news 28 Posted March 9, 2009 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.

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!!
