Intel Pentium 4 2.66GHz vs Pentium 4 2.00GHz

The Intel Pentium 4 2.66GHz is newer than Intel Pentium 4 2.00GHz also around 16% faster in multi-threaded (CPU Mark) testing, it is around 19% faster in single-thread testing. However, Intel Pentium 4 2.66GHz uses around 20% more power. All the CPUs in this comparison belong in the Desktop CPU Class.The values below were tabulated from a combined 262 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.
