Intel Atom x7809C vs AMD Ryzen Z2 A

Both CPUs were released (or first benchmaked) within the last year, but AMD Ryzen Z2 A is around 9% faster in multi-threaded (CPU Mark) testing. It is also significantly faster in single-thread testing. Also, Intel Atom x7809C uses around 50% more power. All the CPUs in this comparison belong in the Mobile/Embedded CPU Class. The values below were tabulated from a combined 7 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.
