AMD Athlon II X2 245e vs Intel Core i7-2600K

Mini Review

AMD Athlon II X2 245e advantages



AMD Athlon II X2 245e
  • The microprocessor has 3DNow! instructions enabled. This technology can enhance performance of some old games and software. The 3DNow! set was depreciated, and not used in modern programs.
  • Power consumption of the processor is better.

Intel Core i7-2600K advantages



Intel Core i7-2600K
  • The Intel Core i7-2600K is 92% faster in single-threaded applications.
  • Multi-threaded performance of the i7-2600K is higher.
  • The Intel i7-2600K performs 195% better in memory-intensive programs.
  • The i7-2600K CPU incorporates SSSE3, SSE4.1 and SSE4.2 instructions.
  • The microprocessor supports AES instructions, that provide AES encryption acceleration. The technology is useful if you need to secure your disk or network data.
  • The Intel i7-2600K has AVX instructions. Although these extensions are not broadly used by applications yet, their support should improve in future apps.
  • The Intel Core i7-2600K is not "locked". Thus, the CPU can be effortlessly overclocked on most motherboards to get greater performance. Be warned that overclocking can void microprocessor warranty.
  • Besides 4 CPU cores, the microprocessor includes HD 3000 graphics. This GPU can be used for casual gaming and 3D applications.

AMD Athlon II X2 245e and Intel Core i7-2600K 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. ASUS P8P67
2. ASROCK M3A780GXH/128M
3. ASUS P8H61-M

RAM - Memory:
1. 2 GB DUAL-CHANNEL CORSAIR TR3X3G1600C9 DDR3
2. 2 GB DUAL-CHANNEL CORSAIR CM3X1024-1333C9 DDR3

VID - Video card(s):

Athlon II X2 245e vs Intel Core i7-2600K 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.
