I've only watched the Gamers Nexus review linked in my original post and he says the 3900x's power consumption is a little high vs what AMD claims but they're going to upload a separate video to go over it in more detail, they did post this chart which shows the 9900K consuming a ton of power when overclocked 5+Ghz but when comparing stock vs. stock it's using less power than 3900X:
I game at 1080P 144Hz with RTX 2070 / i7 8700K I'm totally happy with my current setup and wont be upgrading for awhile but still interesting to keep up on new CPU releases.
I was mainly concerned with the 3900X's SMT enabled performance but it varies by game, this is probably worst case scenario:
But after skimming through Anandtech's review just now it's crazy how much different the results can be from one review to another, I'm just gonna let the dust settle before making any further comments lol.
