AMD FX-6100 vs Phenom II X4 955 (125W, rev. C3)
AMD FX-6100 advantages
- The FX-6100 packs more CPU cores than the AMD 955 microprocessor. Large number of cores helps this processor to handle multiple simultaneous threads or processes.
- Operating frequency of the microprocessor is higher than the frequency of the 955 processor.
- The microprocessor supports SSSE3, SSE4.1 and SSE4.2 instructions.
- The FX-6100 has AES extension to the instruction set. This technology provides hardware acceleration of AES encryption and decryption, and is beneficial if you run programs, that protect your disk or network data.
- The AMD FX-6100 incorporates AVX, FMA4 and XOP instructions. These extensions are not extensively used in applications yet, but their support should improve in future apps.
- The FX-6100 features unlocked multiplier. The processor can be freely overclocked on most motherboards to get greater performance.
- The microprocessor is 24% more energy efficient.
AMD Phenom II X4 955 (125W, rev. C3) advantages
- The 955 has 3DNow! technology. While the 3DNow! technology may enhance performance of some old games and software, it is now obsolete, and it is no longer used by modern programs.
FX-6100 vs 955 specifications comparison
The graphs below compare the most important 955 and FX-6100 characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a CPU performs. The "Operating frequency" graph uses dark color to represent base frequency, whereas lighter area is for extra frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
