AMD Athlon II X4 640 vs Intel Core i3-2100

Mini Review

AMD Athlon II X4 640 advantages



AMD Athlon II X4 640
  • The AMD 640 is 13% faster in multi-threaded applications. The difference in performance is task specific. In some of them the processor could be up to 34% faster.
  • This microprocessor features 3DNow! instructions. While the 3DNow! instruction set may improve performance of certain old games and software, it is now obsolete, and it is no longer used in modern programs.

Intel Core i3-2100 advantages



Intel Core i3-2100
  • The processor is 51% faster when running single-threaded programs.
  • Memory performance of the Core i3-2100 is better.
  • The microprocessor includes SSSE3, SSE4.1 and SSE4.2 instructions.
  • The i3-2100 processor supports AVX instructions. These extensions are not widely used by applications yet, but their support should improve in future programs.
  • The i3-2100 has integrated HD 2000 GPU. This Graphics Processing Unit replaces low-end graphics card, and thus lowers the cost of the system.
  • Power consumption of the CPU is lower.

Athlon II X4 640 vs Intel Core i3-2100 graphics benchmarks

Graphics benchmarks depend on the type of integrated or discrete graphics adapter, and to less extent on the processor performance. Because these benchmarks are synthetic, they may not truly represent gaming performance. However, they still can be used to estimate whether one processor will perform faster or slower than another CPU in games and other 3D tasks.

Important! The processors were tested using different types of graphics adapters, that may not be suitable for comparison.
