Fastest Intel Processors

Mhz/Ghz matter. So does IPC (Instructions per clock). Word width
determines which architecture you must have to run on.

Consider that the IBM Power4 chip runs at 1.3Ghz yet it has the
fastest SPECFP2000 of any machine on the list(1169). IBM Power chips
have always used substantial on chip parallelism. A 2.2Ghz P4 is
766 for SPECFP2000.

Keep in mind that the way to measure how well a processor works is 
to use your own codes and decide which one does it best for the $$$$
