Mini Review

AMD Athlon II X4 640 advantages



AMD Athlon II X4 640
  • The Athlon II X4 640 has 3DNow! technology. Although the 3DNow! instructions may enhance performance of some old games, they are now obsolete, and they are not utilized by modern applications.
  • Based on current official prices, this CPU is 43% cheaper.
  • The Athlon II X4 640 has 40% better price/performance ratio.

Intel Core i3-3240 advantages



Picture

available
  • The microprocessor is 72% faster in single-threaded programs.
  • Memory performance of the CPU is better.
  • The Intel Core i3-3240 includes SSSE3, SSE4.1 and SSE4.2 instructions.
  • The Core i3-3240 microprocessor features AVX and F16C instructions, that appeared in modern processors not too far ago. While these extensions are not widely used in applications yet, their support should improve in future programs.
  • Besides 2 CPU cores, the i3-3240 incorporates HD 2500 GPU. This Graphics Processing Unit replaces low-end graphics card, and thus lowers the cost of the system.
  • Power consumption of the microprocessor is lower.

Benchmarks

System setup

Below is a complete set of AMD Athlon II X4 640 and Intel Core i3-3240 benchmarks from our CPU benchmark database. The former processor was tested on ASRock M3A780GXH/128M motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400). The latter processor was tested on ASUS P8H61-M motherboard, that had 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Integrated on-chip Intel Sandy Bridge graphics.

All tests were performed at default frequency and voltage, using manufacturer's stock fan/heatsink. None of the components were overclocked. Motherboard BIOS options were left at default settings.

The results of all benchmarks are broken into four categories: multi-threaded, single-threaded, memory intensive and graphics / gaming.


Athlon II X4 640 vs Intel Core i3-3240 single-threaded benchmarks

Single-threaded benchmarks run on a single CPU core, and do not depend on such features as the number of cores, or Hyper-Threading technology. Additionally, they do not utilize on-chip caches, dedicated to other cores.

Athlon II X4 640 vs Intel Core i3-3240 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.
