available
  • Multi-threaded performance of the microprocessor is better. The difference in performance depends on specific program. In some of them the FX-6300 could be up to 67% faster.
  • Memory performance of the FX-6300 is better.
  • The AMD FX-6300 processor supports AES technology. This extension provides hardware acceleration of AES encryption and decryption, and is beneficial if you need to secure your disk or network data.
  • The CPU has F16C, FMA3 and XOP instructions enabled. These extensions are not extensively used in applications yet, however their support should improve in future apps.
  • The microprocessor incorporates FMA4 instruction set extension. The FMA4 technology is only available on AMD processors, thus it may not get broad support from software vendors.
  • The FX-6300 is unlocked. Consequentally, the CPU can be easily overclocked on most motherboards to achieve higher performance. Be aware that overclocking voids warranty of the microprocessor.

Benchmarks

System setup

Below is a partial set of AMD FX-6300 and Intel Core i3-2125 benchmarks from our CPU benchmark database. The former processor was tested on ASUS Sabertooth 990FX motherboard with 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and MSI R6670 1GB GDDR5 (ATI Radeon). The latter processor was tested on ASUS P8P67 motherboard, that had 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon) graphics. For different system configurations please see tests of FX-6300 and Intel Core i3-2125 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.


FX-6300 vs Intel Core i3-2125 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.

FX-6300 vs Intel Core i3-2125 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.
