Io-tech.fi did some testings with different memory settings. Included are speeds from 2933MHz upto 3600Mhz, with additional The Stilt's 3466MHz settings that are inlcuded in Crosshair VII Hero's bios. The article is in finnish, but it's waste to translate anything as pictures tell everything...
They did improve nicely with memory for sure. But if you look at that last review, it shows that there is still huge gains to be made by setting subtimings manually. As ashes of singularity didn't get the ~30% boost we've seen from tighter subtimings do. Faster memory hardly did any difference...
Even if Intel would be able to summon magically fast gpu for gamers, moving to such card would be risky for consumer, as Intel really has horrible reputation when it comes to their divers. And unfortunately that reputation changes very slowly.
Even if Intel would end up bringing up great GPU's for market, and even in gaming, they will have to fight the driver battle. AMD has been fighting for a long time to clear their name with having bad drivers, and still their past haunts them even today. Intel's drivers have even worse reputation...
Well is the Skylake-X "poor" gaming performance really from changed cache layout, or is it simply that currently they have slow thread to thread communication latencies (which can be lowered by overclocking cache).
Offtopic. I really hate to whine, but would it be possible to add spoilers in...
It could be because core to core ping times are rather slow. Moving from Ring to Mesh seems to be causing problem especially in games. In Ryzen's case we learned that when certain threads were running on different CCX, there was very clear penalty for peformance. Atleast in Zen's case latency...
Some more impressive scaling with fast memory and low latencies in Ashes of the Singularity's cpu focused test.

Summary from most critical clockspeeds:
2400MHz 40,4
3200 MHz 45,2
3200...
If you look at the test posted on previous page you can see things being completely opposite. In all honesty different applications and games react differently to changes, and there can't be direct summary which on is more important. Best is ofc have more bandwidth with lower latency.
True, these few individual tests are everything we got so far. Well hopefully when new BIOS versions with new AGESA comes out officially, we'll see some sites actually retests Ryzen memory.
Here is another test , this time from Witcher 3 by Keketin...
The Stilt's point with the graph was to show balance between bandwidth versus latency. You can clearly see Latency makes more difference than bandwidth. These LL data sets have also subtimings changed that weren't possible before latest AGESA updates AFAIK.
