But you can believe that 8 PolyMorph engine Kepler is much faster than 16 polymorph engine Fermi?
AMD is AMD, NVidia is NVidia. NVidia can.

@up – sh*t 😉 last line was corrupted, however I think you know what I meant.
The compute software is not optimised to take advantage of 680 yet.
No. It is fault of that design. For compute (not simple math but heavy data) new SMX are only better from VLIW4/5 SIMD Cores but are worse than older Fermi SMs and new GCN SIMDs (that’s why Kepler loses even in Civ V ComputeShaders test). That architecture resembles some of previous AMD designs. VLIW was quite effective in games (pixel shader mostly) and had some fine uses in Collatz Conjecture @ Home (thanks to great throughput of simple math and fine integer + bitwise performance), bitcoin mining (same as before) or MilkyWay@Home (FP64 performance not artificially limited). GK104 is also game oriented architecture and not heavy compute. It can do all those complicated tasks but is not as efficient as Fermi so it takes twice the Fermi peak performance to get about the same real life performance.
One thing that should be noted is that the Radeon 7k[7970 – 7870] have only 2 Tesselators, whereas the Kepler 680 has 8. One AMD Tesselator seems to have 1.5-2X performance over one Nvidia Tesselator.
Now my problem is: AMD wy y no fit more Tesselators into GPU Design?
