AMD Phenom CPU reviews are out.
Daily Tech has some links: http://www.dailytech.com/11192007+Daily+Hardware+Reviews++AMD+Phenom+and+Intel+Core+2+Extreme+QX9770+Edition/article9702.htm Here's Tom's Hardware's review: http://www.tomshardware.com/2007/11/19/the_spider_weaves_its_web/ Looks like they are about 10% slower then the Intel Quad cores at equivalent core speeds. They work on the AM2 platform and have a lower retail prices then Intel.

10% is not too shabby if they're also cheaper. Should make the AMD fanboys happy. Honestly, these PCs have gotten so fast now that these benchmarks are almost meaningless, and for gaming your GPU is far more important than your CPU.
