Three-channel and four-channel performance difference how much

Four channels for bandwidth and so on, so that memory performance can be better played, however, at present, four-channel performance improvement is not particularly obvious, but for those who can choose such a motherboard and CPU players, four-channel memory is a must-choose, but for the game of practical effect is not small, the gap is very little.

The test platform aspect of course is X79 with SNB-E processor to test the four-channel memory, the test method is to make it into three channels and four channels, test performance gap.

Tutorial

3D Theoretical performance test: 3DMark 11

DMARK11 test scores, under the comprehensive results, four-channel memory than the three-channel memory 2% higher performance improvement.

Aida64 Memory Performance Test

In the AIDA64, you can clearly see four channels and three channels of the gap, bandwidth and so on the promotion is also inevitable thing, so read, write replication on the gap is so obvious is very normal.

WinRAR Memory Performance test

WinRAR as a very popular compression software, we use its built-in performance testing function, support multithreading, test results can effectively reflect the CPU's multithreaded performance and memory performance, test results reflect the four-channel and three-channel gap.

PCMark 7 Performance Test and summary

In the comparison between four channels and three channels, we can see that there is a gap between the PCMark test scores, but it is not as obvious as expected.
