AMD A6-3650 vs Intel Pentium D 945

Mini Review

AMD A6-3650 advantages



AMD A6-3650
  • The AMD A6-3650 is 34% faster in single-threaded tasks.
  • Multi-threaded performance of the AMD A6-3650 microprocessor is better.
  • In memory-intensive programs, the AMD A6-3650 is 149% faster.
  • The processor supports hardware acceleration of virtualized tasks.
  • The A6-3650 incorporates 3DNow! instructions. The 3DNow! technology allows the CPU to perform certain floating-point operations faster, and thus increase performance in games, that support the instructions. This technology is obsolete now, and only some old games and software used them.
  • The microprocessor comes with integrated Radeon HD 6530D GPU. This Graphics Processing Unit replaces low-end graphics card, and thus lowers the cost of the system.

Benchmarks

System setup

AMD A6-3650 and Pentium D 945 processors were tested using different system components, that are identified by MB, RAM and VID columns in the tables below. The numbers in each of these columns correspond to one of motherboards (MB), memory configurations (RAM) or graphics adapters (VID), listed below:

MB - Motherboard(s):
1. ASUS F1A75-V PRO
2. INTEL DP965LT

RAM - Memory:
1. 4GB DUAL-CHANNEL CRUCIAL BALLISTIXPC3-14900 (DDR3-1866)
2. 2GB DUAL-CHANNEL CORSAIR CM2X1024-6400C4

VID - Video card(s):
1. MSI R6670 1GB GDDR5 (ATI RADEON)
2. INTEGRATED ON-CHIP ATI RADEON 6000-SERIES GRAPHICS
3. POWERCOLOR 24PRO256M DDR2 (ATI RADEON HD2400)

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.


A6-3650 vs Pentium D 945 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.

A6-3650 vs Pentium D 945 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.

Important! The processors were tested using different types of graphics adapters, that may not be suitable for comparison.

A6-3650 vs Pentium D 945 memory performance

Memory-intensive tests or programs move large amounts of data to/from memory, and they depend more on memory throughput and the size of on-chip caches, rather than on CPU integer/FP/SIMD performance.
