Benchmarks
System setup
Below is a partial set of AMD A8-3870K and FX-6100 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 MSI R6670 1GB GDDR5 (ATI Radeon). The latter processor was tested on ASUS Sabertooth 990FX motherboard, that had 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and MSI R6670 1GB GDDR5 (ATI Radeon) graphics. For different system configurations please see tests of A8-3870K and FX-6100 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 FX-6100 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 FX-6100 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 used to estimate whether one processor will perform faster or slower in games than another CPU.

A8-3870K vs FX-6100 memory performance
Memory-intensive tests or programs move large amounts of data to/from memory, and they depend more on memory throughput and the size of on-chip caches, rather than on CPU integer/FP/SIMD performance.
