Benchmarks

System setup

Below is a partial set of AMD A8-3870K and Intel Core i5-2320 benchmarks from our CPU benchmark database. The former processor was tested on ASUS F1A75-V Pro motherboard with 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and Integrated on-chip ATI Radeon 6000-series graphics. 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. For different system configurations please see tests of A8-3870K and Intel Core i5-2320 CPUs in our benchmark database.

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.


A8-3870K vs Intel Core i5-2320 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.

A8-3870K vs Intel Core i5-2320 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.
