The GT300/Fermi Thread

[570091D]

The PS3 RSX chip is essentially a 128-bit version of NV's G70 architecture, with half the ROP count and half the memory bus width. How is that faster than the original implementation?

it uses rambus xdr ram, much MUCH more bandwidth than the original. from what i hear, the RSX chip is about 3 times faster than a 7800gtx. but are we really discussing weather a 7800gtx can play gta4 in the fermi thread?
