DDR4 Memory Scaling On Skylake (Legitreviews)

[Rekx]

Legitreviews did a really nice report on which RAM clock speed has the best price/performance for Skylake. 

 

 

Shortly ahead of the Intel Z170 platform launch we heard that the memory controller Intel developed for Skylake was amazing and that the new Intel Core i7-6700K and Core i5-6600K could come close running DDR4 4000 MHz memory kits in dual-channel. Just days before Intel launched their two new K-Skus that are aimed at enthusiasts and gamers we noticed that G.Skill released a dozen new dual-channel DDR4 memory kits with speeds ranging from 2133 MHz to 4000 MHz. G.Skill is the first company to release retail memory kits at 4000MHz and it took the release of the latest 6th generation Intel Core processor and Z170 motherboards to make that happen!

This chart shows that you are getting 606MB/s of memory bandwidth per dollar spent on the 2666MHz kit, so from a price to performance aspect the best memory clock speed in the G.Skill Ripjaws V series would be that one! The 3600MHz hit actually gives you the lowest price vs. performance score of 128 MB/s per dollar. The 3000 MHz kit isn’t too far from the top as it came in at 602 MB/s!

Summary: RAM-speed doesn't matter for gaming.

 

Thank me later

Yeah not the same then

 Wrong.

 

Different game engines utilize memory in different ways. Frostbite is a good example showing pretty decent differences between say 1600mhz and 2133 mhz. 

Other considerations;

- Memory channels

- CPU Threads

- Latency 

- Use of CPU Cache

- Memory Latency

He said RAM speed doesn't matter.

Not "RAM choice as a whole doesn't matter"

The only time where RAM speed makes a significant difference in gaming is when using integrated graphics, regardless of the game engine.

 

EDIT: Some proof here

You're forgetting about BF4. It's basically the only exception, but it is an exception.

The exception which proves the rule

I agree, but it's still worth mentioning.
