Intel i3-8350K vs i5-8600K

The Intel Core i3-8350K @ 4.00GHz is newer than Intel Core i5-8600K @ 3.60GHz and is around -32% slower in multi-threaded (CPU Mark) testing. However the CPUs have comparable single-thread rating. Both CPUs operates at simliar power levels (TDP). All the CPUs in this comparison belong in the Desktop CPU Class. The values below were tabulated from a combined 4023 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.
