Benchmarks
System setup
Below is a partial set of AMD A6-5400K and Intel Core i3-2120 benchmarks from our CPU benchmark database. The former processor was tested on ASRock FM2A75 Pro4-M motherboard with 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and Integrated on-chip ATI Radeon 7000-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 A6-5400K and Intel Core i3-2120 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.
A6-5400K vs Intel Core i3-2120 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.

A6-5400K vs Intel Core i3-2120 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.

A6-5400K vs Intel Core i3-2120 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.
