How badly will a 3600 bottleneck a 3080 at 4k?

I’m currently on a Ryzen 1700 with a 1070Ti. I can get a good price on a used 3080 from a friend. Hoping I can keep my current B350 mb with PCIe 3.0 and Wraith cooler to save $, and that I can just drop in a 3600 and the 3080 and call it a day. Decent plan?
 
Should work great most of the game is loaded into the GPU, I have a 3080 it is a nice card blazing away at 2K. Bottleneck performance is overhyped.
 
At 4K, with a 4090 that far, far outclasses your 3080, there is an avg 33% difference between a 3600 and the top 7800x3d. I would say you will be just fine.

7800x3d = 100%
3600 = 75%
75 *1.33 = 100
average 33% improvement at most upgrading to top gpu/cpu

That being said, you will absolutely be bottlenecked in the CPU games (Borderlands, Spiderman, AoE IV, Far Cry 6) to some extent.

Thanks for the feedback. I know it's going to be fairly game-dependent, but just wanted to get some opinions about whether I would be leaving much of the 3080 on the table. Been looking at the Microcenter bundles for awhile but too many other expenses to justify a bigger upgrade.
 
I mean I played BL3 on a 2700x and 1080ti at 1440p high at 60+ all day long.... you'll be fine as long as you don't bother with RT games

You can pickup a new 5600x I think for $150. Might try to snag that with the 3080 imo. Would be a pretty huge upgrade over a 1700

I’d definitely be looking at a 5600x but my motherboard can’t support it. https://www.asrock.com/mb/AMD/AB350 Pro4/index.asp#CPU

It does support it, they just never updated the QVL. If you read the BIOS descriptions it says so and plenty of people have done it. (Vermeer are 5000 series chips). Be VERY careful reading the descriptions because just like Gigabyte you have to do a specific sequence of BIOS upgrades to get there if you decide to do it.
 
It will be more than enough for 4K but I'd also spring for the 5600/x as it's a significant upgrade over the already decent 3600

Will depend on the game. Most games, maybe 1-2 frame rate difference.

If you're looking to a cheap stop gap, I would get the 3600 and in the next year or so move to AM5 once they sort out issues like long boot times.

From my own experience, my 3900X *WAS* a bottleneck for my 3080 at 1440p where I was trying to hit over 100fps.
Not so much at 4k60 except for the management sims I love so much where it was a bottleneck all the time. Damn you Planet Coaster!

The 4090 better outperform my 3080 at almost 2x the price, still overkill at 1440p. RT has lost its hype. Diminishing returns here.

Curious what GPU are they using?

2080ti. Generally at 4K it doesn't matter much. 7800X3D? Sure it will be a good bit faster, but a 3600 compared to 5600? Negligible at best.

Borderlands 3 is very CPU dependent for some reason and typically skews most of those relative performance charts. However a 3600 will run it just fine with a modern GPU.

IMO if you're trying to save some money I would go with a 3600 for less as a stop gap. Next year AMD should hopefully have AM5 issues ironed out, new motherboards, and new CPUs. I'm selling a used 3600 for $85, so it does depend on how much you pay for it. $130? Go with the 5600 for $150. If you can snag a cheap 3600 for $100 or less? I would go for that. 5600 isn't worth 50% more. If you're on a B350 board, put that into savings for a bigger upgrade next year.

So, the 3080 is quite a bit faster than a 2080ti. Your benchmarks aren't 100% accurate then imo.

The results won't differ much.

These benchmarks have a RTX 3080 and the results are essentially the same:

BL3 is an outlier, for some reason it loves CPUs:

Even then, that is a 4 frame rate increase over a 3600.

I do not mean to question a person's monetary habits but these comparisons are nonsense, the delta FPS from 84 to 77.9 FP(FC 5) is not going to be noticeable, if I built these PCs and covered them up you could not id what CPU you were gaming on. Now if the HW/game combo produced stutter or some other breaking bug, yeah you might claim that one CPU combo is better than the other rig.

So just wondering, the OP hasn't mentioned what resolution he will be playing at. If its 1080p or 1440p, those results will be vastly different.
 
I'm at 4k (and 60 hz), it's in the title. Thanks everyone for your thoughts. I went with a $97 5500. I know the 5600/5600x are clearly superior but this is only meant to last my aging system another 18 months or so. Then I’ll build a new system with Granite Ridge or whatever Intel’s next gen will be. I think for my needs I’ll see very little difference between the 5500 and 5600.
