AMD Athlon II X2 250e vs Intel Core 2 Duo E7400

Mini Review

AMD Athlon II X2 250e advantages



AMD Athlon II X2 250e
  • Single-threaded performance of the AMD 250e is better. The difference in performance is task specific. In some of them the microprocessor could be up to 11% faster.
  • Multi-threaded performance of the 250e CPU is higher.
  • In memory-intensive programs, the 250e has 20% better performance.
  • 3DNow! technology is supported by this microprocessor. The 3DNow! technology helps the processor to execute certain floating-point operations faster, and thus increase performance in games and software, that support the instructions. These instruction are obsolete now, and only some old games and software used them.
  • Power consumption of the microprocessor is lower.

Benchmarks

System setup

AMD Athlon II X2 250e and Intel Core 2 Duo E7400 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. ASROCK M3A780GXH/128M
3. 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.


Athlon II X2 250e vs Intel Core 2 Duo E7400 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.

Athlon II X2 250e vs Intel Core 2 Duo E7400 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.
