Benchmarks

System setup

Below is a partial set of Intel Core i5-2500 and Celeron B840 benchmarks from our CPU benchmark database. The former processor was tested on ASUS P8H61-M motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Integrated on-chip Intel Sandy Bridge graphics. 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. For different system configurations please see tests of Core i5-2500 and Celeron B840 CPUs in our benchmark database.

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 i5-2500 vs Celeron B840 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 i5-2500 vs Celeron B840 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.
