AMD FX-8350 vs Intel Core i7-4771

Mini Review

AMD FX-8350 advantages

  • XOP instructions are enabled on this processor. Even though these extensions are not broadly supported by programs yet, their support should improve in future applications.
  • The microprocessor incorporates FMA4 instruction set extension. The FMA4 technology is only offered on AMD processors, and it probably will not get broad support from software vendors.
  • The clock multiplier on the AMD FX-8350 processor is not locked. Therefore, the CPU can be easily overclocked on most motherboards to achieve higher performance. Be aware that overclocking voids warranty of the processor.
  • Based on current official prices, the AMD FX-8350 is 38% less expensive than the Intel Core i7-4771.
  • The AMD FX-8350 CPU has 32% better price/performance ratio.

Intel Core i7-4771 advantages

  • The microprocessor is 58% faster in single-threaded programs.
  • Multi-threaded performance of the CPU is higher.
  • In memory-intensive tasks, the processor has 17% better performance.
  • The microprocessor has 2% higher performance when running graphics programs.
  • The Intel Core i7-4771 CPU incorporates AVX2 instructions, that appeared in modern microprocessors not too far ago. These extensions are not extensively used by applications yet, however this should improve in future apps.
  • The microprocessor comes with integrated HD 4600 GPU. This graphics replaces low-end graphics card, and thus lowers the cost of the system.
  • Power consumption of the Intel i7-4771 is lower.

FX-8350 vs i7-4771 performance comparison

The charts show performance of FX-8350 and Core i7-4771 processors in a number of different kinds of programs. To determine displayed numbers we averaged results for several benchmarks for each specific type of application. As such, the shown results may differ from results, that you may see in individual tests. We also averaged the numbers for task type specific benchmarks and all-around performance benchmarks, and presented them in the 'Overall performance' chart. The 'Price-performance ratio' shows how much more performance you will get per dollar spent. The cost of other system components is not included in the ratio chart.

Benchmarks

System setup

Below is a complete set of AMD FX-8350 and Intel Core i7-4771 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 Intel DH87RL motherboard, that had 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 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.


FX-8350 vs Intel Core i7-4771 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-8350 vs Intel Core i7-4771 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.
