Intel Xeon E3-1220 v3 vs Xeon E5603

The Intel Xeon E5603 @ 1.60GHz is newer than Intel Xeon E3-1220 v3 @ 3.10GHz however is significantly slower in multi-threaded (CPU Mark) testing. However, it is significantly slower in single-thread testing. Both CPUs operates at simliar power levels (TDP). All the CPUs in this comparison belong in the Server CPU Class. The values below were tabulated from a combined 395 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.
