I did this EXACT upgrade… If your asking 12700K to 14700K specifically for gaming only… while you will get higher fps it won’t be much because the 12700K was barely ever maxed out to begin with at 1440P and up so it will feel like a waste of $ at this time. This will just give you a higher ceiling and longevity. If you do a lot of multi monitor stuff on top of gaming with background applications with discord streaming web browsing etc. the e core difference definitely helps a lot more than the actual P cores. Example is downloading games off of steam. Unless I forced steam to run on P cores with a 12700K the download speed would cap out around because the e cores would pick up that task and couldn’t handle faster than that. With the 14700K it’s not even remotely an issue I get my full 1.3Gbps of speed with steam downloads.

I have a genuine question. Would people feel better if they just dropped APO support entirely for all CPUs and just said screw it ?
