HKEPC compared a high-end Core 2 with an AMD Athlon 64 FX-62.
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 at 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.
