High speed RAM...point of diminishing returns???

[TahoeDust]

So, with all the new high speed stuff coming out (G.Skill is showing off 4800MHz stuff at computex! ) at what point is the increased speed not noticeable in real life?...how about in common benchmarks like Firestrike, Superposition, Time Spy, etc? I am going x299 with a 7820x...in my excitement I ordered 4x4gb of Corsair 3200MHz to commit to the build. I don't mind spending a little more if the gains will be there, but don't really want to do it just to say I have it.

With Skylake, most reviewers had DDR4 3200 as the point of diminished returns for "real life" use. However, synthetic benchmarks will keep going up and up with the faster RAM.

The problem with your question is nobody knows for sure until the new hardware is released and reviewed. x299 and the i7-7820x officially support DDR4 2666, up from the DDR4 2133 that z170 / Skylake officially supported. That's all that is really known as of right now until the hardware sites start their reviews.

There comes a point when the user's reaction cannot keep up with the system. Further increases in speed are only apparent with benchies.

Absolutely. The human factor, not to different to what was explained in the Tom Hanks "Sully" movie. You might far exceed in computer speed the delay of simply transmitting data from your sensory organs to your brain or back again. Same thing applies to SATA versus NVMe SSD.

I guess I'm glad that I got 14-14-14 DDR4-3200 G.SKILL TridentZ. I've even come to a point where I can see that I don't need to double the 16GB to 32. Of course, it might have cost me less than the NVMe drive -- which shows its value mostly in caching SATA-HDDs.
