Intel Core i3-2100 vs Pentium G870


Mini Review

Intel Core i3-2100 advantages



Intel Core i3-2100

  • This microprocessor has 19% higher performance when running multi-threaded programs, or when running multiple single-threaded applications.
  • In memory-intensive tasks, the Intel i3-2100 processor is 21% faster.
  • The CPU incorporates AVX instructions. While these extensions are not widely used by programs yet, their support should improve in future applications.


Intel Pentium G870 advantages



Intel Pentium G870

  • Based on current official prices, the Intel Pentium G870 is 36% cheaper.
  • The Intel G870 has 43% better price/performance ratio than the Intel i3-2100.


i3-2100 vs G870 performance comparison

The charts in the section below illustrate performance of Core i3-2100 and Pentium G870 processors in a few different types of programs. The numbers in the charts are calculated from several benchmarks, that you can find in the "Benchmarks" tab. As a result, the displayed results may differ from results, that you may receive in individual tests. We also averaged the numbers for application type specific benchmarks and all-around performance benchmarks, and presented them in the 'Overall performance' chart. The 'Price-performance ratio' chart calculates how much more performance you will get per dollar spent. This ratio does not include the cost of other system components.
