Intel Pentium D 805 vs Duo T2050

The Intel Pentium D 805 @ 2.66GHz is newer than Intel Core Duo T2050 @ 1.60GHz also around 11% faster in multi-threaded (CPU Mark) testing but the CPUs have comparable single-thread rating. However, Intel Core Duo T2050 @ 1.60GHz uses substantially less power. All the CPUs in this comparison belong in the Desktop CPU Class.The values below were tabulated from a combined 270 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.
