  • The i3-520 supports hardware acceleration of virtualized programs.
  • SSE4.1 and SSE4.2 instructions are enabled on this processor.
  • The i3-520 CPU works in Socket 1156. The processor can be easily removed from the socket for replacement or upgrade.

Intel Pentium U5400 advantages

  • None

i3-520 vs U5400 specifications comparison

The charts below show the difference between U5400 and Intel Core i3-520 most important characteristics. These features, along with an IPC (instructions per cycle) number, determine how well a CPU performs. The "Number of cores / threads" graph displays 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. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
