Hi Pavan.

Great comparison. Finally the 1 TFlops barrier broken for the 680. Somewhat disappointing performance as such though. With low-cost 580 cards with 3 GB memory they seem very attractive.

I assume you do not count the PCI transfers. Could you include that also? In my apps I sometime need to consider if it is worth the effort to move the data, compute on the GPU and return the result to the host. Would be nice to see them compared. The disadvantage is that the PCI transfers (latency, rate) varies quite a lot from computer to computer. Interesting it is though.Torben
