Intel Xeon E5-2666 v4 vs AMD Ryzen 7 PRO 8840U

Both CPUs were released (or first benchmaked) within the last year, while AMD Ryzen 7 PRO 8840U is around 25% faster in multi-threaded (CPU Mark) testing, it is around 44% faster in single-thread testing. However, AMD Ryzen 7 PRO 8840U uses substantially less power. The CPUs selected in this comparison belong in different CPU Classes: Server, Desktop, Laptop. Consider, selecting CPUs from simliar CPU Class for more apt comparison.The values below were tabulated from a combined 32 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.
