The results here were very interesting. I had my Vantage results handy from the 580s for both Performance and High Quality modes so it was a good opportunity to compare. First, the 580s (with CPU at 4.1Ghz) in Performance:
54682. Not a bad score for firstname.lastname@example.orgGhz and Tri-SLI overclocked (900Mhz). Now for the 680s, also at 4.1Ghz with cards at 111%:
60432. Not a dramatic difference from the 580s – about 10%. I think here we are beginning to see diminishing returns at this resolution with the CPU being a constant. A bump here would require a bigger proc – the GPUs just aren’t breaking a sweat in either case.
Now lets look at the “High Quality” results. First, the 580s:
21600. A huge hit on the 580s going into High Performance mode. At the time I was surprised by the impact of the move to the High Quality settings. So how did the 680s do?
49557! Wow! Now that is a massive showing for the 680s. At 1680×1050 they destroyed the 580s. Extremely interesting and it shows that Even a modest bump to just under HD resolutions, at high details, is a bigger hit on the GPUs than it is on the CPU (at least at Nehalem 4Ghz level).
Thats it for now. More conclusions coming soon!
