The Ultimate Intel Core i7 Memory Performance Guide

Frequency Performance: Synthetic

With the timings locked at the same settings for all modules, we saw a significant performance difference between memory speeds in the WinRAR test.

While the multi-thread performance between DDR3-800 and 1066 was minimal, the gap widened when comparing DDR3-1066 and 1333 configurations.

This time when testing with PCmark Vantage we see consistent performance gains as the memory frequency is increased right up to 1600MHz.

The CINEBENCH R10 mutli-CPU rendering test shows small yet consistent performance gains as the memory frequency is increased.

The same is true for the OpenGL render test, though the DDR3-1333 memory configuration was slightly faster than the slightly higher clocked 1600MHz memory here.
