Intel Ultra 5 135U vs 3 100U

Both CPUs were released (or first benchmaked) within the last year, while Intel Core Ultra 5 135U is around 16% faster in multi-threaded (CPU Mark) testing, but Intel Core 3 100U is around 11% faster in single-thread testing. However, Intel Core 3 100U uses substantially less power. All the CPUs in this comparison belong in the Laptop CPU Class.The values below were tabulated from a combined 235 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.
