Benchmarks

System setup

Below is a complete set of Intel Core i3-530 and Pentium D 945 benchmarks from our CPU benchmark database. The former processor was tested on ASUS P7P55D motherboard with 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400). The latter processor was tested on Intel DP965LT motherboard, that had 2GB dual-channel Corsair CM2X1024-6400C4 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 i3-530 vs Pentium D 945 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 i3-530 vs Pentium D 945 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.
