Benchmarks

System setup

Intel Core 2 Duo E7400 and Pentium E5500 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. ASROCK 4CORE1600TWINS-P35
2. INTEL DP965LT

RAM - Memory:
1. 2 GB DUAL-CHANNEL CORSAIR CM3X1024-1333C9 DDR3
2. 2GB DUAL-CHANNEL CORSAIR CM2X1024-6400C4

VID - Video card(s):
1. 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.


Core 2 Duo E7400 vs Pentium E5500 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 E7400 vs Pentium E5500 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.
