Pcie 4 confusion for intel comet lake (eg 10700k)....

wunkley · 16 Apr 2021 at 12:43

Been out of the loop for a while on the cpu and motherboard front so apologies if this is a daft question, but are there any motherboards out now that support the intel 10700k, that also have support for a future pcie 4 GPU and pcie 4 M2 ssd drives?

Is this not possible? Is it only intel rocket lake and amd 5000 series that have this?

The 10th generation cpu only supports pcie3 you can get a motherboard that has pcie4 such as a b560 or z590 which will work woth the 10th gen series cpu but only at pcie3 speeds.

You would need a 11th gen cpu such as a 11700k for pcie4.

See this is where I start to lose the plot!

I was thinking of possibly getting an 11400f on a b560 board for now, and then in future when more cores for gaming will be good, switch the cpu for an 8 core 10700k or 10 core 10900k. But if I did this would I therefore lose any pcie4 functionality that was there with the 11400f? GPU wise and M2 ssd wise?

it’s all very confusing.

Nothing confusing at all.
With 11400F your GPU will run at Gen4, your NVMe (if it supports PCI-e4) will run at Gen4 speeds.
With 10900k your GPU will run at Gen3 speeds and your NVMe will run at Gen3 speeds
Provided we are talking about b560 boards

If you want pcie4 you need the 11000 cpu and a b560 or z590 notherboard

10th gen and its pcie3 thats it.

Ok thanks that clears that up, but spoils my plans. Bugger.

I only tend to upgrade my cpu and motherboard every 5 years or so. Just trying to factor in how much pcie 4 and the lack of it will be an issue in future, or not. Especially on the GPU side....

Also would there be anything wrong with sticking a 10700k in a reasonable b560 motherboard for now? There are some good prices at the mo on 10700ks. Although the ‘upgrade’ from a 10700k to an 11900k in future would be the ceiling of rocket lake, so apart from gaining pcie 4 ability it wouldn’t really be worth it would it? Gahhhh. Wait for alder lake or next Ryzen maybe?

11400 should be good for a while i suspect it would last you 5 years but could drop in a 8 core if needed . I certainly would pay extra for the intergrated graphics as that can be very handy especially if you dont have another gpu for back up.

Whats your needs , gaming, syreaming and at what resoloution ?

Thanks bud. It's 90% gaming really for the rig in question. I game at 3440x1440 at 90Hz, 4k 60Hz and now VR on the Reverb G2 which is insane high res. I'm not a low res hig fps type gamer. I'm currently on a x99 5930k at 4.6Ghz with a 3090FE. Some people tell me there's little point upgrading my CPU for my gaming needs, others say I will still see good gains. My main gripe at the moment is Flight Sim 2020 in VR which has given me the upgrade 'bug' again, but it sounds like no system can really run it well in VR yet.

I'm thinking to do a fairly cheap experimental upgrade to an 11400 or 11400f on a b560 and sell my current cpu, mb and ram. Will end up not costing too much then, but I really can't be bothered with the hassle of changing everything out if I won't see any substantial gains in gaming.

If buying this week would you get an 11400 (With which MB) or a 10700k (With which MB)?

mickyflinn · 16 Apr 2021 at 18:04

Put it off this weekend and do some testing use msi afterburner and test cpu usage and if it hits 100% its bottleneck . Also check you fps and 1% lows and see if there any dips.

There will be some gains having pcie4 depending on games but that could be from 0 to 10%.

If all your other games run fins at the resoloution you want i would hold off.

wunkley · 16 Apr 2021 at 18:20

My cpu never hits anything like 100% in any games I play. I have HWinfo64 data running in widgets on a second screen when gaming to monitor stuff.

It really is just the one game (Flight Sim) that has started the upgrade demons rolling. Daft really.

If your going with something like a B560+11400 then I'd just sit on it for 3 years then upgrade to a new DDR5 based system as even the budget offerings by then will easily trump any upgrade to a higher core count CPU on the LGA1200 platform for gaming especially with how fast CPU tech is now starting to advance.
