Benchmarks

System setup

Intel Core 2 Duo E4500 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. ASROCK 4CORE1600TWINS-P35
2. INTEL DP965LT

RAM - Memory:
1. 2 GB DUAL-CHANNEL CORSAIR CM3X1024-1333C9 DDR3
2. 2GB DUAL-CHANNEL CORSAIR CM2X1024-6400C4

VID - Video card(s):
1. 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.


Core 2 Duo E4500 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.

Core 2 Duo E4500 vs Pentium D 945 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.

Core 2 Duo E4500 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 used to estimate whether one processor will perform faster or slower in games than another CPU.

Core 2 Duo E4500 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.
