Intel's 45 nm Penryn CPU: 4 GHz Air Cooled

Overclocking - Up To 19% More Performance

We compiled a performance analysis of the individual programs that make up our benchmark suite, with the processor overclocked to 3.33 GHz and 3.66 GHz.

We didn't include synthetic benchmark applications such as SiSoft Sandra, PCMark and 3DMark, since they are not real-world applications and would therefore not contribute to these results in a meaningful way.

The Core 2 Extreme QX9650, running at 3.3 GHz at stock voltage, shows a 6.6% performance boost across our benchmark suite.

When we raise the processor's clock speed to 3.66 GHz, which only requires a minor increase in core voltage, its scores improve by 13.3%.

All of our tests were run on the Gigabyte GA-X38-DQ6 motherboard.
