Test Results: Single Vs. Dual Channel RAM
Let’s now answer the more important question: is dual channel memory really worth it?
3DMark06 only cares about high graphics and CPU performance. It doesn’t seem to mind us switching the 2 GB total main memory from dual channel to single channel operation.
Call of Duty 2 runs approximately 4.2% slower on the same hardware when dual channel mode is not used.
The performance difference in Prey is very small: 1.6%.
There is even less of a difference under Quake IV.
