GPU bottlenecking

[dh2005]

Hello,

 

I bought myself a new PC (everyone, this is Dorothy... Dorothy, this is everyone...) a few weeks ago. Every component was brand new and the best that I could source locally, apart from the graphics card - which is a Sapphire Nitro+ 5700 XT, previously in a Razer Core X Chroma eGPU enclosure attached to a Mac mini (because that setup was worth the money...).

 

I was thinking of getting a 6800 XT or something, as soon as I saw one for a semi-defensible price - but yesterday night I watched a Gamers Nexus video on the Ryzen 5900X CPU (which I'm using), and in the gaming benchmarks they were conducting they stated repeatedly that their RTX 3080 was bottlenecking all of the higher-end CPUs, to the point of rendering more CPU power moot.

 

My question is, do we expect the next generation of cards to go beyond that threshold? Because I don't really want to buy a new GPU this year, then replace it shortly afterwards.

 

Thanks to all for your insights.

 

 

 

 

DH.

I think the reason nobody has replied to your question @dh2005 is that we don't quite understand what you're saying here...?

A 5600/5800/5900/5950X will perform about equally, depending on the game, with the 5900X and 5950X usually being on top. The general computing experience is going to vary depending on your workload.

 

TLDR; a 5900X together with an RTX 3080 is a wonderfully balanced config and one of the best combinations out there for gaming and general computing. The 5900X is pretty much as good as you can get, as far as consumer (gaming) CPU's are concerned. The same goes for the RTX 3080. The only better choice is the 3080 Ti or 3090 (if you need more VRAM) - they literally don't make anything better than that

The RTX 3000 series, as well as AMD's 6000 series represent quite a large leap in performance, or I should rather say performance/$ - that obviously doesn't apply anymore, but you get the point. 

Will future GPU's be better? Yeah, sure they will. I'm assuming not by a lot, but they will.

 

I think what your asking for doesn't exist..

I don't have a 3080 but even my 2080 ti has issues at 1080p in most games.

Here is Assassins' Creed Valhalla at the highest preset. 1080p looks pointless since there is only a 6 frame difference between it and 1440p.

Also notice that the GPU is at about the same usage and mhz at all 3 resolutions.

 

 

With RDR 2 the 1080p and 1440p frames are almost the same so it is a no brainer to play it at 1440p.

 

 

I am a 4k gamer and my modern CPUs are not working hard at all at that resolution.

And there you have it @dh2005.

 

• At high resolutions: CPU is chilling, not processing many FPS -> GPU more important = ALWAYS GPU bottleneck no matter what
• At low resolutions: CPU needs to process A LOT of FPS -> GPU less important = CPU bottleneck more likely

 

TLDR; if you're planning to play games at high resolutions (4K) there's not going to be much difference between something like a 5900X and a much older CPU, since everything depends on your GPU. If you're planning to play games at low resolutions and high framerates (1080p @alotofhertz) there IS going to be a big difference between modern fast CPU's and old slower CPU's
