Intel E6850 Bottleneck Investigation
Benchmarks, Part 2
In this next set of benchmarks we see the E6850 down-clocked to 2 GHz affecting performance by just 2.76% overall, while doing the same percentage underclock to the GTX285 reduces performance by 31.02%. Again, this is almost a linear performance drop from the GPU and confirms it’s the bottleneck by almost 100%.
We see slight movement in Jericho and Unreal Tournament 3 from running the CPU at 2 GHz, but this is again vastly overshadowed by the much bigger impact the GPU has.
Call of Duty 4 and Wolfenstein show absolutely no movement from the CPU dropping to 2 GHz, and the latter game also shows completely linear scaling when underclocking the GPU.
