AMD Athlon II X3 455 vs Intel Core i3-2100

Mini Review

AMD Athlon II X3 455 advantages



AMD Athlon II X3 455
  • 3DNow! instructions are supported by this microprocessor. The 3DNow! technology helps the CPU to perform certain floating-point operations faster, and thus boost performance in games, that support the instructions. This technology is obsolete now, and only some old games and software used them.

Intel Core i3-2100 advantages



Intel Core i3-2100
  • The processor is 38% faster when running single-threaded tasks.
  • Multi-threaded performance of the microprocessor is better.
  • In memory-intensive applications, the Intel Core i3-2100 is 38% faster.
  • The i3-2100 incorporates SSSE3, SSE4.1 and SSE4.2 instructions.
  • The Core i3-2100 has AVX instructions, that were introduced in modern processors not too far ago. While these extensions are not broadly used in programs yet, their support should improve in future applications.
  • The Core i3-2100 comes with integrated HD 2000 GPU. This graphics unit replaces low-end graphics card, and thus lowers the cost of the system.
  • Power consumption of the Intel i3-2100 is lower.

Athlon II X3 455 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.
