PCIE4

[britfrog]

hi, having recently built a new rig for msfs i now see the spectre of PCIE4 coming up which will no doubt increase significantly a p.c,s performance.

my first question is will an i7 9700kf understand pcie4 and make use of it~?

do any of these 9th or 10th generation intel cpu's understand pcie4 coding?

in the event that 9th gen cpus dont work with pcie4 i presume it will be a waste of time looking for a socket 1151 m/b with pcie4?

looking forward too your thoughts

The chipset and the cpu's lanes are gen 3, not gen 4, and for the most part, unless you're saturating the bandwidth of gen 3 for a gpu or an m.2 etc, you wont notice an improvement in performance.

I have a PCIe 4 compatible GPU (5700XT) along with an X570 board and a Zen 2 CPU and I can say, with 100% certainty it makes zero difference. Only last week I had to stick my GPU in my uncles PC, he has an X370 board and a 2700X CPU. While it was in there I ran Firestrike to test if there was any difference and the GPU score on his PC ended up being within 10pts of what I get on mine.

No current Intel CPU supports PCIe4, and it's not a big deal because nothing makes real use of it yet.

PCIe 4.0 or 3.0 doesn't make any difference for the normal consumer. The only noticeable difference is in the SSD space, when you often have to move big files around. Otherwise it's not really worth the consideration.

Gen 4 SSDs do, the issue there is the increase in speeds you get from the Gen 4 SSD don't make anything any faster than if you just bought a Gen 3 one.

you should doubt it

especially in gaming workloads

no, the board and CPU both doesnt support pcie 4.0

they dont exist

only some LGA1200 boards are "PCIE 4.0 ready", but no CPU that uses PCIE 4.0 exist on LGA1200 yet

arguably useless unless you like copying files a lot lol

I said "real use".

 

People most of the time can't even tell the difference between a SATA SSD and a theoetically "7x faster" NVMe, so the 2x increase from PCIe3 to PCIe4 is utterly irrelevant unless you have VERY uncommon use cases.

But I, Circletech, Use my computer for copying the same 400GB P0rn file from one drive to the other, day after day after day. 

A PCIe 4.0 drive would still make that faster.
