lol 1536cores is apparently true and possible perf.,
GTX680 = GK104
1536 Cuda Cores
2GB 5.0Gbps GDDR5
950MHz core (with "turbo core" 1050mhz)
well to be honest it looks as expected, rivaling Amd 7950-7970 for a little lower price.
but overall its still weaker, i mean only 40-50% faster then GF110 512core (stock clock) with 3x more cores? ok..
I guess its because of lower bandwidth, same 16compute units and less ROPs
I think Gk110 is going to be that killer, hopefully in Q3-Q4 2012 like GF110 2years ago?
