Most energy-efficient gaming CPU?

[xc3ll]

Hi Guys,

 

since I am running out of RAM lately and do not want to invest in my fairly old platform, I am looking for a replacement of my 4790k. As most of todays CPUs are easily capable of running all games on my 3440x1440/100Hz Monitor, my focus is more on efficiency than performance. I run a SFF-case with an Noctua NH-U9S, so I am also thermally limited to ~90W CPU TDP (during gaming) on full GPU load.

 

So, which CPU gives the lowest Watt/FPS at an avg. of 100FPS?

 

If you know any reviews, which have FPS and power-consumption without GPU logged, a link would be also much appreciated!

I did not consider the 5600 before, as it is a little older. However, the prices are quite interesting right now!

The 5600G is available on sale right now and less expensive than the 5600X. As it is higher clocked, is there any reason to go for the 5600X?

Higher single core boost and double the cache. Both things that are important for gaming.

Yeah, should've read the full specification

Okay, 5600X. Still, quite a good deal.

Just ordered the 5600 (non X), as I found it on sale.

Overall upgrade cost incl. RAM and Mainboard is less than a i5-13600k

I have a 5600X running in my sons system, its a fine CPU. And it is so easy to cool, you can do it in silence.
