Quad Channel vs Dual Channel Ram on Ryzen/TR CPU (gaming)

[cosmogenesis]

I noticed that you can get a 8C/16T Ryzen (12nm) and Threadripper (14nm) and I thought well maybe dual channel vs quad channel ram might make a difference in gaming. Anyone know if it does as from what I can tell its only in min FPS levels and not actual max fps performance boosting ?

Any one know more about it?

Ryzen 3/5/7 support only dual channel
TR4 supports Quad channel.

What Ryzen 3/5/7 will benefit from is dual rank dual channel ram.
It gains some extra performance in games by using dual rank compared to single rank.

TR4, is a different beast all together with changes coming.
If the new Dynamic Mode works with dual channel ram, it will be a boon.

Otherwise manually switch to game mode effectively forcing all games to the fist chip, rendering inner the second chip having access to the other channel of ram.
So even if you have quad channel on TR4, it will work as dual channel, since games don't like the topology. But all these will change with the new Dynamic mode. So stay tuned for update.

Negligible difference for gaming applications between dual and quad, latency is the important thing in gaming. It can provide an improvement similar to going dual rank but it is small.

Gaming wise for same clocks Ryzen should be quicker than TR as it doesn't slit communications across 2 die.
