Performance to be gained...?

I have an RTX 3090 which is paired with a 10900k which sits around 4.8ghz on all cores. Last year or so I've given a great deal of thought about moving over to AMD. I've always had Intel and its not like I'm unhappy with them, although their latest are not for me, but I get AMD are where its at at the moment.

Question is though, would I actually gain performance in games at 4k moving to a 5900 or a 5950x?

Not unless you're playing 2 games at once.
 
At 4K you are GPU bound not CPU bound.

10900K to 5900X wouldn't do anything with a 3090 at that resolution.

Also you can run a 10900K at 5.1 all cores easy on a 240mm+ AIO. Maybe upgrade your CPU cooler instead if you want a bit more CPU performance.

Mine craps out at 5.2 all cores and needs way too much more voltage, but it does 5.1 all cores at 1.28v max LLC.

This is a great resource, I actually did think the AMD CPUs were still a bit better at all resolutions, but it looks like they aren't at high resolutions.

So best thing to do if you have a 9900K or better from Intel is upgrade the monitor, or turn up AA / DSR on lower resolution monitors.

Im running the CG437KP 4k monitor so the monitor is just fine.

Would I actually gain anything in game bumping it to 5.1ghz? It DOES go that high Ive done it before but Ive just found that 4.8ghz on my 360mm H115i @1.25 gives me good gains with little heat and the fans can run slower.
 
I'd wait for another year and see what DDR5 brings to the table. And by then you'll most likely have a choice between the next-gen of both AMD and Intel.

9900k here, and I still feel that there is nothing out there CPU-wise that is worth upgrading to yet. And this chip will be 3 years old this October.
 
Would be a sidegrade at best infact I think Intel perform slightly better at 4K although your only talking like 1fps.

The only thing worth overclocking at 4K is the GPU and even then you would only be getting around +5% fps.

If you have a 360mm AIO and are only running a 10900K at 4.8 all cores, then you seriously need to learn how to overclock.

Its a lot more than simply bumping the clocks up, you need to set higher LLC, reduce AVX offset and maybe a few more power delivery tweaks as well.

I just set everything else to max (LLC and several power limits), 280mm Corsair H115i in a mini ITX case and it stays under 75c in all games, under 85c in stress tests at 5.1 all cores.

5.2 needed 1.35v+ and 95c+ in stress tests so never mind doing that, even though it was gaming stable. Not worth the extra heat.

The 5.1 all cores at 1.28v is actually doing completely fine in summer as well as long as I keep the window and door open. It would be fine on a 240mm AIO with faster fans too.

On a 360mm AIO I could do the 5.2 all cores easy, but its still not worth the extra voltage and heat output.

My main issue is that I like having a 280mm AIO and two HDD in Raid 1 in my current Phanteks mini ITX case. All the new ITX cases that support triple slot GPUs either lack the 280mm AIO space or the two HDD slots, as well as then being stuck with a total of 4 ITX cases :x

And I still have two ATX cases stashed at my parents house that I haven't been able to retrieve with the rest of my stuff due to the lockdown, will have them and loads more stuff to somehow store after I'm fully vaccinated.

Well I'm quite dumb, I could reuse an old ATX case after I get it back to have a triple slot any 3080+ card for now.

Yeh I don't think it would be worth it at the moment but like it's been said above maybe see what DDR5 and next chipsets bring, AMD smashed it last time and looks like they have more tricks to come yet so wait n see what they do and if Intel pulls the finger out this time round
 
The 5900X will crush pretty much all of Intel range in most scenarios, nevermind the 5950X. But if the systems main use is gaming and considering you have to replace a motherboard and possibly OS for a CPU upgrade I’d just stick with what you have.

This, a quid a day/week/month wouldn't bother me but I feel some on this forum think it's a big thing when buying a CPU or GPU.

It depends, obviously, but if you use the PC a lot, particularly if it's under load or doing something time sensitive, then these kind of decisions can cost way more than a quid, well worth considering in the long-term. But, worth switching from a 10900K for a gamer a few hours a day? Nope.

I'm sorry, but saving £365 a year isn't a big deal for you? Now yeah, no point in purchasing hardware purely to make that saving because you'd never recoup the outlay, but if you're planning a new system and hardware choices could net you over 300 notes in a year, why in the blue hell would you not factor that?
