Synthetic Benchmarks: SiSoft Sandra

How Many CPU Cores Do You Need?

We'll begin with SiSoft Sandra's CPU arithmetic and CPU multimedia benchmarks:

These synthetic benchmarks are showing us a very linear progression between one to four CPU cores. Frankly, this benchmark software is written in a way to utilize multiple cores very efficiently, but I doubt many real-world applications are going to be able to duplicate this linear progression.

Sandra's memory benchmark suggests that three cores will be more memory bandwidth friendly when it comes to integer buffered iSSE2 operations.

Synthetics have their place, but let's get into the meat and potatoes of this review: application benchmarks.
