We review the new XT model Ryzen 9 3900XT. Released by AMD as a respin of the 3900X model, the XT processors are optimized to bring a bit more bite in single-threaded and medium threaded workloads.

Quite interesting... Zen2 architecture is capable of these massively high clocks... just not in the entire chip at the same time.
I wonder what kind of design error they did that prevents that ?
Maybe the power delivery substrate layers are insufficient to provide consistent energy to all the cores at the same time, or it just gets way too hot internally.
Here's hoping that Zen3 can actually do ALL-core overclocks of 4.5+ with ease !

Another reason these benchmarks do not make sense to me. XT performed a bit lower in the time spy CPU score, but it overall beats the X variant in the total score.
How is that if it performs a bit slower yet it is considered higher performing in the overall score?
Less means more now??

My 3900X runs hot as hell honestly.
My 3960X is cool as a cucumber in comparison. This is with a 480mm radiator, 280mm and a 120mm on my 3900X. It can hit 80C while folding. GPU (5700XT) doesn't touch 60C on the same loop.
Typical temps are around 31-65 under regular loads and not folding and or doing crazy intensive CPU work.
Under full load, 75 Degrees C with the Kraken X62, no thanks

Personally, I would recommend against all XT chips. Performance difference is marginal at best, but you reset those discounted price to MSRP and in case of 2 out of 3 CPUs also buy a cooler. And actually, I would highly recommend 3600, 3700X or 3900X ad alternatives. Yes you lose little bit more performance, but you get a lot lower price. 3600 is 170USD part, while 3600XT is 250USD. And if you really need more work performance, 3700X is 270USD and productivity wise demolishes 3600XT. And 3800XT is is just few percent better than 3700X but costs 400USD. If 3700X is not enough, 3900X is just like 422USD on Amazon and again blows it out of the water, plus comes with stock cooler. And if you are really after gaming FOS and don't care about value, then why are you even talking about AMD, get 10600K, overclock it and it will either perform same or better. Plus where it is better it is still far more noticeably better than XT parts are. And don't get me wrong, I love what AMD did with Zen2 and recommend it. But they will need to make sense for me to recommend them.
As for only place I see those usefully, it is with overclockers and tinkering, because they will allow you to do more. Or if you like to "play" benchmarks instead of games. Which is fine, but I can't see this being major usecase.
So yeah, get best value and don't pay for extra letters, about 50USD for each and +1-4% performance.
