Tom's Interactive CPU Charts offer the most comprehensive x86 processor comparison on the Internet. The 2008 edition includes as many as 91 AMD and Intel desktop processors, which we tested across 35 individual benchmarks under Windows Vista. The benchmarks include industry standard software as well as popular workloads across multiple application categories, allowing you to find the CPU that meets your requirements (see benchmark details below the charts). The Charts are also a valuable tool if you want to check how your computer stacks up against current hardware. The 2008 charts include three different processor generations, starting with AMD's Socket 939 Athlons and Semprons, and including all Pentium 4 and Pentium D processors that were released for Socket 775.
