HKEPC tests Core 2 Duo power draw, overclocking
HKEPC has joined the Conroe benchmarking bandwagon with some early Core 2 numbers
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.
