The CPU Scorecard - Manufacturer Benchmark Links, Resources & Information

A word of caution about CPU benchmarks...
When you get right down to it, computer processor benchmarks are an imprecise and transitory method of comparing how fast/well/suitably a given list of computer systems will perform for you.

They are prone to error, skew, and hype. They are highly dependent upon the specific test configuration from which they result. And the various speeds and capabilities of the individual computer hardware components (hard drive, bus, memory, video, et al) in a system can be at least as important to overall performance as is the speed of the CPU.
