AMD FX-8350 vs Intel Core 2 Extreme QX9775

Mini Review

AMD FX-8350 advantages

  • More CPU cores on the AMD FX-8350 help to tackle multiple simultaneous threads or programs.
  • The AMD FX-8350 offers higher operating frequency than the QX9775.
  • The processor has SSE4.2 instructions enabled.
  • The CPU features Advanced Encryption Standard technology. This extension accelerates AES encryption and decryption, and is valuable if you need to protect your disk or network data.
  • The FX-8350 processor includes AVX, F16C, FMA3 and XOP instructions, that were introduced in the recent past. Although these extensions are not widely supported by applications yet, their support should improve in future apps.
  • The FX-8350 CPU has FMA4 instruction set extension enabled. The FMA4 technology is only available on AMD microprocessors, thus it probably will not get broad support from software vendors.
  • The AMD FX-8350 features unlocked clock multiplier. The microprocessor can be easily overclocked on most motherboards to achieve greater performance. Be warned that overclocking can void CPU warranty.
  • The AMD FX-8350 microprocessor is 17% more energy efficient.

Intel Core 2 Extreme QX9775 advantages

  • None

FX-8350 vs QX9775 specifications comparison

The charts below compare the most important characteristics of the QX9775 and AMD FX-8350 CPUs. These features, together with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Operating frequency" graph uses dark color for 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. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
