Intel Pentium III 1400 vs AMD Athlon XP 2000+

The Intel Pentium III 1400 @ 1400MHz is newer than AMD Athlon XP 2000+, while the multi-threaded (CPU Mark) is simliar, AMD Athlon XP 2000+ is around 13% faster in single-thread testing. However, Intel Pentium III 1400 @ 1400MHz uses substantially less power. All the CPUs in this comparison belong in the Desktop CPU Class.The values below were tabulated from a combined 57 benchmarks submitted from our PerformanceTest software and results and are updated daily to include new submissions.

  • The first section will show basic information for each CPU selected.
  • The additional graphs shows the CPU Mark and Single Thread values of each CPU selected.
  • An accompany graph, if price data is available, will shows the value for money, in terms of the CPU Mark/Thread Rating per dollar.
  • The last section will show approximate yearly running costs for the CPUs.
