AnandTech Reviews Athlon64
I thought a hardware article would be a nice change of pace today, so I found a review of the Athlon 64 and Athlon 64 FX over at AnandTech. The review goes into detail about AMD's latest processors and then provides benchmarks under 32-bit Windows so we can know what kind of performance to expect. Most of the benchmarks were on par with the fastest Pentium 4 Extreme Editions, a processor that Intel is releasing to compete with the Athlon 64 and coincidentally I did not make up.
An interesting part of the article were the Linux benchmarks, because with Linux you can have native 64-bit support simply by recompiling the OS and the applications. Therefore they were running the benchmarks in a native 64-bit environment. The performance increase when compared to 32-bit was about 10-20% using standard open source programs. Definately worth recompiling/patching to get 64-bit support, especially once WinXP64 hits shelves.
