Intel U300 vs i3-N305

The Intel U300 is newer than Intel Core i3-N305, while Intel Core i3-N305 is around 17% faster in multi-threaded (CPU Mark) testing, but Intel U300 is around 27% faster in single-thread testing. Both CPUs operates at simliar power levels (TDP). The CPUs selected in this comparison belong in different CPU Classes: Laptop, Mobile/Embedded. Consider, selecting CPUs from simliar CPU Class for more apt comparison.The values below were tabulated from a combined 261 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.
