Call me dense, but why is the limited benefit of 32GB-capacity being conflated with the CPU-cache masking memory latency?
If you have a 20GB of data in use the CPU-cache is not going to mask the advantage of having 32GB over 16GB - the 16GB system is going to have to page out to the SSD or HDD dramatically lowering performance.
The larger CPU-cache does mean there is often less impact from lower latency or higher bandwidth sets - but capacity, depending on the workload, can have a dramatic impact.
It's absolutely fair to say 32GB may be of limited benefit on most consumer workloads compared to 16GB, but it has nothing to do with the size of the CPU's cache.
Your own testing showed that the Photoshop test absolutely benefitted from the additional memory capacity, but there was little difference between ddr4-2666 and ddr4-3200 in that or the other real-world tests.
"Eyeing up a Core i7-6950X and a GTX 1080? Then you'll want some potent DDR4"
You keep saying things like this in the leaders, but then your test results consistently show that higher speed DDR4 offers almost no measurable benefit. Is there a known restructuring of OSs on the horizon that's going to make a difference for high-spec DDR4, or is this the end of the story?
IMO that's the message they're sending. "If you're already looking at ridiculously over-the-top components just because, this memory is for you" kinda thing. People that just want the best of the best, regardless of how it affects real-world applications.Quote:

The 'Law of diminishing returns' definately seems to apply to memory from the speed point of view.
It would seem more logical to have more memory rather than faster memory particularly if you have a niche area that exploits that.
The law of diminshing returns applies less to amount than it does to speed, overall.
And it's still true - my 2GB tablet feels very responsive for web browsing, sending emails, typing letters, etc - the stuff MOST people do with their computers. I notice very little real world difference between using the tablet and using my laptop, which has 8GB of faster RAM. Part of that is the improvement in Windows 10's memory handling, of course, but OSes have actually been getting better at using limited resources over the last few iterations.Quote:

*I used to work with a group of analysts who found that their script running times reduced from minutes to seconds when they all got new machines with 16GB of RAM (the previous ones had 4GB). Turned out that SPSS sorting algorithms are memory intensive; they were hitting > 10GB of memory usage during certain sorts and the old machines were practically grinding to a halt as they swapped like crazy; the new ones were doing the entire sort in RAM. Those workflows do exist, and people should be aware of them, but it doesn't mean the majority of people need more memory...
I found this an interesting read:
http://techbuyersguru.com/gaming-ddr...hz-8gb-vs-16gb
There are similar articles out there that provide the same sort of results - in most configurations, the performance gap between memory speeds is minuscule - so small that it doesn't matter one bit. There is a barely measurable jump between 2133 and 2666 which makes it worth picking up 2666 memory in many cases (and the fact its currently £2-3 cheaper makes it a no brainer for most people), but real no difference above that level.
Much better to buy some 2666 ram with decent timings, 16gb of which will set you back £50-£60, and 32gb about £110-120. £200 does not seem a reasonable amount of money to spend on memory imo when you can spend almost half as much for effectively identical performance.
I'm very interested in purchasing a set of the Black/White and Silver/White for a new build, I do wonder though, how long it is going to take for these to come to Europe? will they even come to Europe? The only place I've seen these listed so far is on Newegg in the US but they don't do international shipping on them :(
Apparently there are issues getting supply of G.skill products into the UK, if anyone knows of someone that has these in stock in the UK or a site that will deliver internationally I'd appreciate it :)
