Intel Core i3-2100 vs Pentium 2127U

Mini Review

Intel Core i3-2100 advantages



Intel Core i3-2100
  • This microprocessor has Hyper-Threading technology. This feature doubles the number of threads that the processor can execute simultaneously.
  • The microprocessor comes with higher operating frequency than the Intel Pentium 2127U.
  • The CPU features AVX instructions. Although these extensions are not widely supported by applications yet, their support should improve in future apps.
  • The Core i3-2100 uses Socket 1155, and can be removed from it without effort. This allows easy processor upgrade or downgrade when needed.

  • The Intel 2127U utilizes more efficient Ivy Bridge core, which offers up to 8% better performance than similar clocked Sandy Bridge CPUs.
  • The Intel Pentium 2127U is 74% more energy efficient.

i3-2100 vs 2127U specifications comparison

The graphs below compare the most important Pentium 2127U and i3-2100 characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph represents the number of extra threads, provided by Hyper-Threading technology. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
