AMD Opteron 165 vs FX-6120

Mini Review

AMD Opteron 165 advantages

  • 3DNow! technology is supported by this processor. Even though the 3DNow! instructions may enhance performance of certain old games and software, they are now obsolete, and they are not used by modern programs.

AMD FX-6120 advantages

  • In single-threaded applications, the FX-6120 is about 77% faster.
  • Multi-threaded performance of the AMD FX-6120 is better.
  • The AMD FX-6120 performs 206% faster in memory-intensive tasks.
  • The microprocessor supports hardware acceleration of virtualized applications.
  • The AMD FX-6120 CPU includes SSSE3, SSE4.1 and SSE4.2 instructions.
  • The microprocessor has AES technology. These instructions provide hardware acceleration of AES encryption and decryption, and are useful if you run programs, that secure your disk or network data.
  • The FX-6120 supports AVX and XOP instructions, that were introduced in the recent past. While these extensions are not widely used in applications yet, their support should improve in future programs.
  • FMA4 instruction set extension is enabled on this processor. The FMA4 technology is only offered on AMD processors, therefore not many software vendors may support it in the future.
  • The clock multiplier on the AMD FX-6120 CPU is not locked. As a result, the processor can be effortlessly overclocked on most motherboards to get higher performance. Be aware that overclocking voids warranty of the CPU.
  • Power consumption of the AMD FX-6120 is lower.

Benchmarks

System setup

Below is a complete set of AMD Opteron 165 and FX-6120 benchmarks from our CPU benchmark database. The former processor was tested on Abit KN8 SLI motherboard with 2GB dual-channel Corsair CMX1024-3200C2PT memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400). The latter processor was tested on ASUS Sabertooth 990FX motherboard, that had 4GB dual-channel Crucial BallistixPC3-14900 (DDR3-1866) memory, and MSI R6670 1GB GDDR5 (ATI Radeon) 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.


Opteron 165 vs FX-6120 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.

Opteron 165 vs FX-6120 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.

Opteron 165 vs FX-6120 memory performance

Memory-intensive tests or programs move large amounts of data to/from memory, and they depend more on memory throughput and the size of on-chip caches, rather than on CPU integer/FP/SIMD performance.
