A8-3870K vs 965 performance comparison
The charts illustrate relative performance of A8-3870K and Phenom II X4 965 (140W, BE) CPUs in various program types. The numbers for 'Single-threaded performance' and 'Multi-threaded performance' charts are calculated as an average of several related benchmarks, that you can see in the "Benchmarks" tab. As a result, performance in individual benchmarks may be higher or lower than what you see in the charts here. We also averaged the results for task type specific benchmarks and all-around performance benchmarks, and presented them in the 'Overall performance' chart. The 'Price-performance ratio' displays how much more performance you will get per dollar spent. This ratio does not include the cost of other system components. | |||||||||||||||||||||||||||||

Benchmarks
System setup
AMD A8-3870K and 965 (140W, BE) 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. ASROCK M3A780GXH/128M
3. MSI K9A2 PLATINUM
RAM - Memory:
1. 4GB DUAL-CHANNEL CRUCIAL BALLISTIXPC3-14900 (DDR3-1866)
2. 2 GB DUAL-CHANNEL CORSAIR CM3X1024-1333C9 DDR3
3. 2GB DUAL-CHANNEL CORSAIR CM2X1024-6400C4
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.
A8-3870K vs 965 (140W, BE) 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 965 (140W, BE) 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.
