Intel Xeon 5150 vs Xeon E5520

The Intel Xeon E5520 @ 2.27GHz is newer than Intel Xeon 5150 @ 2.66GHz and is significantly faster in multi-threaded (CPU Mark) testing but the CPUs have comparable single-thread rating. However, Intel Xeon E5520 @ 2.27GHz uses around 21% more power. All the CPUs in this comparison belong in the Server CPU Class.The values below were tabulated from a combined 233 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.
