AMD A4-4300M vs Intel Pentium III 866 MHz

Mini Review

AMD A4-4300M advantages

  • The A4-4300M incorporates more CPU cores than the Pentium III 866 MHz. Large number of cores helps this microprocessor to process multiple programs or threads at once.
  • The processor has higher operating frequency than the Pentium III 866 MHz microprocessor.
  • The processor supports Enhanced Virus Protection feature, that can protect from certain types of computer viruses.
  • The AMD A4-4300M microprocessor includes AMD64 technology, that allows it to run 64-bit operating systems.
  • Integrated AMD-V feature enhances performance in virtualization tasks.
  • The AMD A4-4300M features SSE2 instructions. Many modern applications extensively use these instructions, and some programs even require them to execute.
  • The CPU has SSE3, SSSE3, SSE4.1 and SSE4.2 instructions.
  • The microprocessor includes Advanced Encryption Standard technology. This extension provides hardware acceleration of AES encryption and decryption, and is valuable if you run applications, that secure your disk or network data.
  • The A4-4300M incorporates AVX, F16C, FMA3 and XOP instructions. These extensions are not broadly supported by programs yet, but their support should improve in future apps.
  • The processor has FMA4 instruction set extension enabled. The FMA4 technology is only available on AMD CPUs, thus it may not get broad support from software vendors.
  • The A4-4300M microprocessor features on-chip Radeon HD 7420G GPU. This Graphics Processing Unit is not a replacement for high-end graphics cards, however it can be used for casual games and 3D applications.

Benchmarks

System setup

Below is a complete set of AMD A4-4300M and Pentium III 866 MHz benchmarks from our CPU benchmark database. The former processor was tested on Jetway NF83 motherboard with 16GB dual-channel Corsair Vengeance CMSX16GX3M2A1866C10 (DDR3-1866) memory, and Integrated on-chip ATI Radeon 6000-series graphics. 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.


A4-4300M 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.
