Most current Intel and AMD CPUs, as well as almost every Macintosh model from the last few years,
geekbenched and compared. Interesting results if you just want to have an overall generic idea of how fast is what. Interesting to see that my 12″ 867 Mhz Powerbook G4 is at least 6 times slower than a new MacBook Pro or that new Core2Duo CPUs at 2 GHz are way faster than my pretty recent 3 GHz P4 (which came with hyperthreading and 64bit support nonetheless). Technology flies fast past you!
