Does XMP undervolt CPU? Or is it just for increasing RAM frequency?

No. 13900k kicks ass bud.

13900k is a beast. Runs everything I throw at it from games to intense audio/video sessions.

No it’s just going to throttle

It’s amazing to see how powerful a Jay Z endorsement is for Intel. All my gaming buddies ridiculed me for building a 13900k and now that Jay is switching to Intel, they wanna know “How’s that Intel working and does it BSOD”? 😮‍💨

A 14900k is going to feel good in intensive task and just everyday snap. Gaming probably won’t be a big shocker but if you want it buy it. Or if you want to save some money buy a 13900K it’s literally the same chip but with fractions of a difference.

I don’t see a point in upgrading from what you have to a 13 or a 14 gen chip. I feel you are looking to just spend money to feel validated and that is fine. Wouldn’t be the last.

Why not get a 13900k? The different is very minimal.
