Benchmarks

System setup

Below is a complete set of Intel Core 2 Duo T5550 and Core i7-2630QM benchmarks from our CPU benchmark database. The former processor was tested on MSI Fuzzy GM965 (MS-9803 V1.0) motherboard with 2GB dual-channel Corsair CM2X1024-6400C4 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400). The latter processor was tested on Supermicro X9SCV-Q motherboard, that had 2 GB dual-channel Crucial CT2KIT12864BC1339 DDR3-1333 SODIMM memory, and Integrated on-chip Intel Sandy Bridge 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 T5550 vs Core i7-2630QM 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 T5550 vs Core i7-2630QM 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.

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