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
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.
