Benchmarks

System setup

AMD A8-3820 and Intel Core i3-540 processors were tested using different system components, that are identified by MB, RAM and VID columns in the tables below. The numbers in each of these columns correspond to one of motherboards (MB), memory configurations (RAM) or graphics adapters (VID), listed below:

MB - Motherboard(s):
1. ASUS F1A75-V PRO
2. ASUS P7P55D

RAM - Memory:
1. 4GB DUAL-CHANNEL CRUCIAL BALLISTIXPC3-14900 (DDR3-1866)
2. 2 GB DUAL-CHANNEL CORSAIR TR3X3G1600C9 DDR3

VID - Video card(s):
1. MSI R6670 1GB GDDR5 (ATI RADEON)
2. INTEGRATED ON-CHIP ATI RADEON 6000-SERIES GRAPHICS
3. POWERCOLOR 24PRO256M DDR2 (ATI RADEON HD2400)

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.


A8-3820 vs Intel Core i3-540 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.

A8-3820 vs Intel Core i3-540 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.

Important! The processors were tested using different types of graphics adapters, that may not be suitable for comparison.

A8-3820 vs Intel Core i3-540 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.
