Does PC4-19200 vs PC4-24000 matter on single GPU builds?

[euskalzabe]

Hi all,

Context: I'm getting a new cpu/mobo/ram in March, whether Zen or KBL, that'll depend on the former's reviews. As I look for known quantity parts like memory, I wonder if PC4-19200 vs PC4-24000 memory speeds make any difference when gaming?

I use a 4K display, though I mostly game at 1080p. Currently on a GTX770, planning on a GTX1060 or its successor soon. The new CPU will be 4-core, don't need 8-core/16-thread for gaming/office use.

So, in this context, is it worth spending the extra money for PC4-24000 memory, or PC4-19200 would be better value?

Thanks in advance.

For Skylake/Kabylake yes.
There are good gains up to 2800MHz and small ones around 3000MHz.
But mostly in cpu limited scenarios which tend to be near/above 60Hz.

For Ryzen, unknown.

I wouldnt use a 1060 at 4K unless you like 30fps.

OK I'll take that into account. Still have to wait to see whats up with Ryzen.

I wouldnt use a 1060 at 4K unless you like 30fps.

I game at 1080p. Only games I run at 4K are old, say, Portal 2. Other than that, it's mostly 1080p or custom res ultrawide. 4K comes in super handy to do all my work - lots of desktop space.

it really depends on the game
you need to be cpu bottlnecked for ram to help as it improves cpu efficiency around 15-30% but most games will be gpu bottlnecked
speeds over 3000 do help a fair bit if you can keep the timings tight but costs can blow out
so ~3000c15 3200c16 is what i recommend to most that just want a mild oc and to load the xmp for ram as its a cheap and easy performance boost

here is a gpu limited game as you can see the gpu oc make more difference than a cpu upgrade and oc

and here some cpu limited games where gpu speed doesn't make much difference and cpu\ram do

Gotcha, thanks for those charts. I'm on DDR3 1333 right now so either way it'll be an upgrade. I like using microATX boards as they leave plenty of space in my case, and even the new KBL ones only support up to 2400mhz, so I'll just have to buy the max speed that whichever motherboard I buy supports.

Thanks again!

Something nice to know i been picking out parts for a new build and was wondering about ram speeds myself.
