Overclocking Core i7: Power Versus Performance
Benchmark Results: PCMark & 3DMark Vantage
PCMark
PCMark Vantage shows almost linear performance gains when overclocking to the various clock speeds. The interesting part will be the analysis of performance versus power consumption, which we did based on PCMark.
3DMark
As expected, the GPU score of 3DMark Vantage doesn’t change much with increasing clock speed.
The CPU score does, however, and it shows nicely that the 4.0 GHz clock speed causes the processor throttle—you can see this by the fact that the 3.8 GHz setting provides more 3DMark Vantage performance.
