PC Looking for more FPS, think about your CPU first and here is why

I last year I upgraded my GPU from a 5800 to a 6800XT. The result was an underwhelming fps increase of about 10-15, from 30-35 to 45-50.
I adjusted the memory setting ReSize BAR in my bios and that got me another 5fps...

I just upgraded my CPU from a;

Ryzen 5 6core 3.4Mhz

to a
Ryzen 9 12core 3.7Mhz

My FPS doubled, and this is on 3x spawn. I have never seen them shamble so smoothly.

According to this website https://pc-builds.com/bottleneck-calculator/

My cpu was just BARELY bottlenecking my GPU at 0.5%. I had heard 7d2d was heavily CPU bound but I didn't give it enough weight at the time. If you are hurting for FPS, look to your CPU first. Mine new Ryzen was $299 and a new GPU upgrade 7800XT is close to $1k.
 

 
Yep, have been saying this for a while, and even demonstrated how much something as simple as overclocking CPU or RAM can make a difference. (source)

Curious though, as "Ryzen 5" and "Ryzen 9" are about at vague as saying "Intel I7", what specific CPU models were they? You just listed a generic quality level that spans several years of different CPU models.

 
Ryzen 5 1600x was from 2017

Ryzen 9 5900x was 2020

Is that what you mean?

Yep, and that is a HUGE difference in generations.  Even the 2600X has poor performance because of a lack of multi-thread/core support in the architecture. The generation after that AMD got with the party, and started giving Intel the first real run for their money in nearly two decades. AMD has been top for performance-per-dollar since.

It isn't just about single-core clock speeds. Sure those are good, but without the supporting architecture, performance can be pretty bad. Just like right now a lot of people with 12-14 gen Intel chipsets are having performance issues rather regularly because a program will end up running on one of their E-Core CPU's instead of a real one.
