Benchmarks

System setup

Below is a complete set of Intel Core 2 Duo E6550 and E8300 benchmarks from our CPU benchmark database. Both microprocessors were tested on ASRock 4Core1600Twins-P35 motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400) 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.


Core 2 Duo E6550 vs E8300 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.

Core 2 Duo E6550 vs E8300 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.
