Best zen 3 CPU for RX 7800 XT?

[Zekkah]

I have a R7 5800X, which bottlenecks the GPU, but I'm happy with the performance and I'll hardly upgrade, but I'd like to know your opinion.

I don't think you'd need a CPU upgrade as the best you can get on an AM4 platform is the R7 5800X3D. Though admittedly, the latter is a fair bit faster in certain CPU intensive games, but only at resolution and in-game setting that does not stress (aka bottleneck) the 7800 XT (which is an excellent 1080P/1440P gaming card). Depending on the game, at lower res, your CPU might be the bottleneck, but at higher res (like 1440P) and higher in-game setting, the GPU might be the bottleneck (depending on the game engine used as well).

I had an R9 5900X in my main rig, I replaced it with an R7 5700X3D as I use my main rig for gaming, the 5900X went into my 2nd rig, replacing an R9 3900X which I'd sold off to cover the cost of the 5700X3D....or, at least, most of the cost. Anecdotally, I see better consistent minimum framerate with higher framerate in CPU intensive games, didn't bother with a before and after benchmark runs of 3DMark.

How have you come to this conclusion? Have you taken the time to look at benchmarks online that are using the same model of CPU and GPU?

Then I don't see a problem.

Every PC always has a bottleneck. Where it is, and by how much, depends on what it is currently doing.

Worrying about a bottleneck existing is a "solution looking for a problem".

Besides, while the 5800X3D and 5600X3D (and less so, the 5700X3D) are upgrades to to you have, it's by no means enough of a difference to make it worth it. So any upgrade would warrant a new platform, and that itself justifies that the difference be larger, and even the 7800X3D is just barely approaching being worth it from your current spot in my opinion.

You could upgrade to 5800X3D and sell your 5800X. Best you can get for your socket and it will last you for quite a while giving decent boost to gaming performance.

NO UPGRADE......I have a 5700x on a 570x motherboard, 32gb of 3600mz memory, EVGA 3080 hybrid 10gb water cooled card with 2tb gen 4 M.2 1tb gen.3 M.2 and a bunch of sata SSD drives.....

with all that said i can max out my 3080 to a real 99% load in most games and your 7800xt is par with most games not going 5 frames off from each other on the GPU side......(not dealing with FSR or DLSS)......our GPUs go toe to toe with each other......

on your CPU you need to be running PBO as it gives a healthy boost on 5000 series chips.....you will need a good CPU cooler for this like a thermalright assassin 120 and also set a voltage off set of at least .025 when PBO kicks in.....

on my motherboard I can keep my 5700x running 4.650ghz ALL CORES with PBO on and a offset voltage of .025.....

cyberpunk is the only game that I see my GPU usage really drop and it goes to 96% load reported in MSI afterburner.....

your 5800x should hit 4.7ghz all cores....not one core IF YOU have a good motherboard, good CPU cooler and play with settings you can really get close to not bottlenecking that card at all.....

with all that said your system is one of the most balanced you can build right now but going up in GPU at all you will need to upgrade motherboard CPU and RAM.....

memory wont be that big of a factor but its times like these I hope you have a X570 motherboard as you wont get everything out of lesser motherboard.....also CPU cooler....every 1C over 72C my 5700x goes I start to lose .50mhz all cores....hope your CPU cooler is good.....

You're right. I might consider the upgrade when the 5800X3D gets cheaper. I can play pretty much all games in 4K at max settings, with some exceptions, but the upscaling options available compensate for it.

There's these two games, Uncharted: Legacy of Thieves and Last of Us Part I, which are not very well optimized, that make me resort to upscaling, and Control, which is the heaviest I tried. I can only make this one run smoothly at max settings in 1440p, but the upscaling is very good though. I guess this is the type of game that would benefit most from a better CPU due to the Ray-Tracing.

I remember reading somewhere that the 5800X bottlenecks this GPU. I don't know where.

I had the CPU manually overclocked to 4.7GHz for a long time, but it was giving me overheating and stability issues that I was not realising. I turned on PBO and did some undervolting and now it reaches a maximum of 4575MHz, from what I can tell from CPU-Z, and I'm getting higher scores with 3DMark.

My cooler is a Cooler Master V8 GTS.

For games that are heavy on Ray-Tracing I guess it would be a great upgrade. Control being a good example.

It might make a considerable difference for games with Ray-Tracing. I think I might get the 5800X3D when it's cheaper, if it's still worth it at that time.

[smokerob79]

the gains wont really be worth it without a better GPU....by the time you are ready for a new GPU you should upgrade the whole rig.....dont waste money on a 5800X3D

everything i can find on the CPU cooler looks weak....its from 2012 and did not get great reviews to begin with....what are the temps when you are at 4.5ghz all cores???

This is what I've been noticing in benchmarks over the last couple years, the X3D really helps smooths things out by improving the minimum frame rates / stutters (1%, 0.1% low).

Bear in mind, the R7 5800X3D is faster in certain specific games, with the right high end card. Now, as to whether you'd see an improvement really hinges on the RX 7800 XT, the CPU you have is a pretty good match for it. And honestly, IF I had your system, I'd pretty much leave it alone.

The reason why I'd gone with the 5700X3D is due to my having a higher end card, an RX 7900 XTX and I don't game at 4k, actually, exactly half of that at 3840x1080, hence my GPU might still have some breathing room. Part of the reason why I'd upgraded was because I'd felt my R9 3900X was getting a little long in the tooth, so by selling it, I'd covered most of the cost for my 5700X3D upgrade.

It gets to 90ºC with the CPU burner from FurMark2.

Keep in mind the RX 7800 XT received a pretty good performance boost from a driver released in 2024. I already had it before that and noticed a huge difference when playing Spider-Man Remastered. Went from having to resort to 1800p with upscaling to running it at 2160p with temporal anti-aliasing, which is pretty taxing. You might be using early benchmarks to judge the GPU.
