The 5800X is a mighty fine CPU, although it can be powerhog. I actually transitioned to the 5800XT last year after they went on sale for $124 on Amazon last year and I repurposed it by including it in a new PC I built last year which I gave away to my brother.

Yeah, I jumped on it as soon as I saw it posted on Slickdeals last year.

5700x is 65 watts if you want lower power and very similar performance.

You can also do this by simple setting 1 value in just about any motherboard's UEFI.

For boards that don't have a single "TDP" setting, then set 88W PPT, 60A TDC, 90A EDC to limit it to the same as any Am4 65W TDP chip. This only slows my 5800X chips in my home servers by 8%. Instead of something taking 10 seconds to complete, it would complete in 9.2 seconds - not a huge difference. A Negative 20 curve optimizer value brings the performance back, and has been solid on my chips. -30 would generate an error about once a week, but was stable in various load tests for days. I run three 5800X chips, and two 9600X chips in my systems.

My 9600X chips can do an incredible -39 CO stable in various stress tests, so I run them at -30. 40% faster per core than the 5800X, and 20% faster all-core.

Is there a significant gain from 5600x to 5800x? Trying to squeeze as much from am4 platform before upgrading.

Well, you at least get 2 more cores for add'l multi-core performance.

I doubt you'd notice a difference in most tasks.
