Meaningful CPU upgrade?

Hey all,

 

I currently have a Ryzen 5 2600(non x) paired with a RTX 2080 Super, together they push to a Samsung G9 at 5120x1440.

I'm considering a 5600x (£200) (preferred) or a 5800x (£320) to replace the 2600, but should I?

 

I mainly play Assetto Corsa Competitzione and iRacing. iRacing is no concern. ACC on the other hand....

 

When I play online, the GPU is maxed at nice looking (not epic) settings, when I race single player, both cpu and gpu sit at around 60% load and my FPS drops from around 95-100 online to sub 60 offline and it chugs at times.

 

Does anyone think the jump to a 56/5800x will lift offline performance much or at that resolution will I see little gains?

 

5700x will also be considered depending on how pricing goes for the 5000 series when the new ones drop.

 

Thanks for any help given!

At that resolution both of those CPU's aren't going to differ much from eachother. What I will say that I say to everyone on the fence is the 5800x is going to use more power and run a lot hotter. Be prepared to spend additional money keeping it cool.

What are the threads of your CPU doing when you're chugging offline in the game?

 

Need to know individual threads, not just a "75%" response

I mean, if you are GPU limited online, the new CPU wont do much for you for online play probably. 

 

If you are CPU limited offline (which you are, judging from 60%GPU usage), the new 5600X will probably boost offline performance quite a bit.

What motherboard are you running and what chipset does it use?

Its an ROG Strix F-Gaming 2 - B450 on the latest bios.

That's what I'm hoping for! 2600 to 5600x should hopefully give me the headroom to run the AI and feed the GPU? Cant hurt for VR as well I suppose?

I've not went really in-depth with this, however, the 6 cores when running ACC single player behave almost identically, they all average around 60% as soon as the session loads. When in an AI race and at turn 1 of lap 1 and we all bunch up, the frame rate dips hard briefly, cpu usage hits 90 then settles back to 60% as the pack spreads. GPU is pretty much at 60% the whole time.

 

Online is roughly CPU cores at 35% and GPU 96-99%. Same stats in replay.

you just said it yourself why:

When offline, the PC is calculating a buncha shit for AI players.  Online it's not.

The CPU number % really don't tell you much nowadays with CPU's having so many cores. You could be CPU limited at 60% CPU load, because it is only using 60 % of the cores or something weird like that.

 

The real measure is GPU usage. If GPU is at 100% --> GPU limited. If GPU is at less than 100% --> CPU limited. It is that simple.

 

So yes, I would imagine you will get better performance single player with an upgraded CPU. I am guessing the game is mostly single core, and the 5600X single core performance should be much better than the 2600.

 

(just FYI it would be EVEN better to upgrade to like a 12600K, but that would require a new motherboard as well obviously).

 

Good luck!
