yeah we are. RS has already decided the winner of the next gen GPUs. its the GTX 880. hurray to the new king. :biggrin:
I didn't say GTX880 would beat R9 300 series, but Maxwell's 20nm 500mm2+ flagship should beat AMD's R9 300 series 20nm flagship. Maxwell is a brand new architecture that NV has worked on for a long time. GCN 2.0 should only be an improvement from 1.0/1.1. Not only that but NV has already beaten AMD with 8800GTX/285/480/580/780Ti. Obviously I am not talking about price/performance. Maxwell already shows a major improvement in performance/watt on the same 28nm node.
Wait, so in his fairy tale world only nv is capable of improving their uarchs? Who would have guessed...
I didn't say AMD won't improve GCN 2.0 from 1.0/1.1. I am saying that NV already shows a real world improvement of 35% from Kepler with 750Ti and that's only on 28nm. When AMD moved from 4870 to 5870 to 6970, there wasn't much improvement in IPC. Mostly rasterization/geometry was improved while the rest came from more TMUs, SPs, ROPs and memory bandwidth. GCN 1.1 also has no real improvement in IPC I can see from 7970 series, just more units. If you look at R9 290X specs, it scales more or less in line with the increase in SPs, TMUs. 660 is just 20% ahead of 750Ti despite having specs that exceed it by 50-66% across the board! Maxwell has shown a significant increase in IPC because 750Ti performs far above its paper specs as compared to Kepler.
I think if AMD wants to compete with Maxwell, it needs to go bigger yet again (beyond 440mm2) or has to implement some new tricks like stackable DRAM.
