AMD FX-8350 vs Intel Pentium III 866 MHz

Mini Review

AMD FX-8350 advantages

  • Many more CPU cores on the FX-8350 help to process multiple applications or threads at once.
  • Operating frequency of the processor is higher than the frequency of the Pentium III 866 MHz.
  • Enhanced Virus Protection feature on this chip helps to protect from certain types of computer viruses.
  • The AMD FX-8350 incorporates AMD64 technology, that allows it to run 64-bit operating systems.
  • Incorporated AMD-V feature enhances performance of virtualized programs.
  • SSE2 instructions, available on this cpu, are used by many modern applications. There are even some programs that require these instructions.
  • The FX-8350 microprocessor includes SSE3, SSSE3, SSE4.1 and SSE4.2 instructions.
  • The processor supports Advanced Encryption Standard 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 features AVX, F16C, FMA3 and XOP instructions, introduced in the recent past. These extensions are not widely used by applications yet, however their support should improve in future apps.
  • The FX-8350 processor has FMA4 instruction set extension enabled. Only AMD microprocessors offer this technology, therefore it probably will not get broad support from software vendors.
  • The AMD FX-8350 is not "locked". The microprocessor can be easily overclocked on most motherboards to achieve greater performance.

FX-8350 vs Pentium III 866 MHz specifications comparison

The graphs below compare the most important characteristics of the Intel Pentium III 866 MHz and FX-8350 processors. These features, along with an IPC (instructions per cycle) number, determine how well a processor performs. The "Operating frequency" chart uses dark color for base frequency, while 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.

Benchmarks

System setup

Below is a complete set of AMD FX-8350 and Pentium III 866 MHz 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 Epox EP-693A motherboard, that had 128 MB PC133 CL3 (Samsung) memory, and ATI 3D Rage Pro (PCI) with 8 MB graphics memory. 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 Pentium III 866 MHz multi-threaded benchmarks

Multi-threaded benchmarks utilize all CPU cores and other on-chip resources (on-chip caches, internal buffers, etc). Intel's Hyper-Threading feature also helps to improve multi-threading performance.
