HKEPC tests Core 2 Duo power draw, overclocking

HKEPC has joined the Conroe benchmarking bandwagon with some early Core 2 numbers (translate here) that paint pretty much the same picture as those in other previews—namely, near-total dominance from the top-end Core 2 over AMD's flagship Athlon 64 FX-62. That isn't particularly news-worthy, but HKEPC also tested power consumption and overclocking with the upcoming Core 2 Extreme X6800. In HKEPC's testing, the Core 2 machine idled at 77 W and climbed to just 118 W during a CPU Burn test. Meanwhile, the Athlon 64 FX-62-powered AMD system drew 98 W at idle and 142 W under load. Those numbers give Intel's flagship a pretty decisive advantage, although we should point out that the AMD machine was running with one of NVIDIA's rather power-hungry nForce 590 SLI chipsets.

Moving on to the overclocking tests, HKEPC managed to boost the 2.93 GHz Core 2 Extreme to 3.6 GHz—a massive 23% jump. Considering Intel's fastest Core 2 models will only hit 3.2 GHz by the end of the year, it's certainly interesting to see this kind of overclocking headroom. Of course, such feats with top-end chips are not uncommon for Intel; in our review of the Pentium Extreme Edition 965, we were able to crank the chip up from a stock 3.73 GHz to a sizzling 4.53 GHz. Hopefully the Core 2 Extreme is able to achieve high overclocks without contributing directly to global warming, though.
