Memory Bandwidth and Latency Benchmarking

SiSoftware Sandra 2014 SP3:

sandra

Sandra needs no introduction as it is the most popular memory performance benchmark available!

hyperx-sandra

Benchmark Results: The Sandra memory bandwidth benchmark shows that the less expensive Crucial Sport VLP memory kit had better memory bandwidth that the Crucial Tatical VLP memory kit by just a very small amount. The Crucial Ballistix might have tighter CL8 timings, but the 2T command rate really hurts performance. We lowered the command rate manually to 1T and the kit was stable and performance went from 21.44GB/s to 21.57GB/s by just changing the one setting!

AIDA64 Extreme Edition 4.60 Beta:

AIDA64 Extreme Edition 4.60 software is an excellent benchmarking tool for looking at memory performance on any desktop PC.

Benchmark Results: AIDA64 showed that the Kingston HyperX Predator with 2133MHz JEDEC speeds and manual tightend timings of 14-14-14-36 1T was good for about 56.0GB/s read and 46.7GB/s write speeds. With the 2666MHz XMP profile loaded up and left at the default timing we improved to 60.1GB/s read and 46.9GB/s write and then at 3000MHz the read speed very slightly crept up to 60.8GB/s read and 46.9GB/s write. There is a pretty good bandwidth increase going from 2133MHz to 2666MHz, but there appears to be a smaller improvement from 2666MHz to 3000MHz due to the loosened timings. You can see the looser DDR4 timings really impacted the copy test results as it went from 62.4GB/s on 2666MHz down to 60.8GB/s at 3000MHz.  It just goes to show you that faster clocked memory isn’t ideal for all situations as timings are still critical.

Benchmark Results: When it comes to memory latency we were getting 69.9 ns at 2133MHz, 68.1 ns at 2666MHz and finally 64.6 ns at 3000MHz.
