Benchmarks

System setup

Below is a complete set of AMD FX-8120 and FX-8320 benchmarks from our CPU benchmark database. Both microprocessors were tested on ASUS Sabertooth 990FX motherboard with 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and MSI R6670 1GB GDDR5 (ATI Radeon) 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.


FX-8120 vs FX-8320 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.

FX-8120 vs FX-8320 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.
