Because Ryzen doesn't work the way traditional CPUs do in regards to power curves and boost/turbo. Instead of saying "This CPU runs at this frequency at this power", AMD says "The CPU is given this much power. We guarantee it will run this fast (base clock), but it may go higher, power and thermals permitting". This gets you power graphs that look like these; Notice how when the used core count goes up, the clocks reduce on each thread which helps reduce the overall package power. AMD can throw in 33% more cores and sacrifice only 3% clock speed at the same power due to where the cores are on the efficiency curve. A core at 4450Mhz draws 18.3w, but a core at 3875Mhz draws just 7.25w! In EPYC and Threadripper, cores in the mid-2Ghz draw just three watts. Additionally, as you can see, low-thread workloads don't even come close to approaching the total power budget. Between binning for better cores and simply having more to pick from, the higher core count parts also get a small low thread frequency advantage. The lower core count parts are given the same power window as the higher core parts to allow them to clock up higher at their given core counts, but it largely makes little difference in the real world as most Ryzen CPUs are already tuned pretty close to their maximum out the gate, which is why you see little to no difference between the 3600 (65w) and 3600X (95w) or the 3700X (65w) and 3800X (105w). Part of this is why AMD introduced "Eco" mode, where you could chose to lower your higher TDP chip to the power window of their lower TDP counterparts. PBO, in comparison, is an extension of these same power limits. If you were to increase the 3900X's power window beyond 140w, the CPU would then use that extra overhead (temps allowing) to start clocking higher in multithread workloads where you would otherwise hit your cap. TL;DR, because Ryzen is already beyond the peak of it's efficiency curve out the box and has started scaling the wall, and because you can easily change the performance and draw of your chip just by adding better cooling and changing your PPT (power window). TDP doesn't really mean anything anymore. Any additional OCing or undervolting you do is just modifying the existing p-states, which you can now do per CCX, but undervolting on it's own may open up more performance just by opening up more PPT.

They did buy SeaMicro back in 2012. FPGAs, just another thing for AMD's semi custom division. Makes sense really.

This post has aged well. ? AMD claims at least that CB20 ST is ~25% higher than the 3900X. 652 is, pretty much dead on, 25% higher than a 3900X. This is plausible.

Was the admin that wrote all the cool stuff (read: GUI menus, manual terrain gain, multi server proxies and chat, etc) at the end actually, but yes, I remember you and all the interesting drama we all caused for Enterprise back in the day, and taking the Builder+ test. I still dabble, but not the the extent it once was. Figured I'd throw up a GT:NH server and see if anyone actually bites. If not, ah well, still get to play with new stuff. I also offered to help @axipher with his server admin side if he wanted it, but I'm not trying to get back into it as deep as before. I regret nothing, but it was work.

TPU usually re-runs their tests every launch; https://www.techpowerup.com/review/msi-geforce-rtx-3090-gaming-x-trio/32.html so spitting distance of each other at this point. They list their driver versions used here; https://www.techpowerup.com/review/msi-geforce-rtx-3090-gaming-x-trio/4.html

The low-core box? Hyper-modded MC server. Need every scrap of ST I can get but don't wanna drop much on it. Looks like a 5900X to replace my 3900X, and then maybe just drop this 3900X in the server and turn off the "bad" CCXs if I cant find a buyer. Maybe some new RAM since my board is QVL'd for 4700 kits if the new CPU's IF can handle it. The 4k APUs have me hopeful.

See, I'm the kind of jerk that would not have noticed it being ad free because ad/tracker blockers and a general (100% justified) distrust of the internet. This situation has been rectified, and serious respect to you for making it ad free for all. Welcome "back" home everyone.

In the market to both upgrade my 3900X as well as hopefully nab a 3300x replacement if AMD provides one at a sane price point. Intel's "no XMP unless you buy Z490" policy combined with the pitiful 2666 stock support has me pretty annoyed at their i3 lineup atm, and 3300Xs are gone everywhere, so here's hoping for a theoretical 5300X out the gate.

HP has Zen2 APUs in their ProBook and EliteBook lineup now if that helps in the long run. If Dell follows suit and makes "sufficient" models of laptop/micro (Read; Quadcore, 8GB, SSD) cheaper than the i5 models, there is a chance that my hospital ministry might pick up on it. Money is money and you don't really need a lot to run Citrix and Word. ... Funny enough, AMD does have a small foothold in the ministry already actually. All of our Thin clients are either AMD or Marvell.

Man, I gotta rebuild my post count again? Also ?

I personally moved from a 1950X and dual 1080tis to my 3900X and 5700XT and it was an up or sidegrade all around as you say; Latency, ST Perf, MT Perf, but the thing you will miss the most will be PCI-e lanes, no doubt about it, given you use two GPUs. The 3950X will be a better all-arounder than the 2990WX, that is for certain, and the 2990WX/X399 should still fetch a decent price since AMD left a gap in their lineup with TRX40. I suppose since your storage is M.2/2.5 and not AIC that you would have fewer issues than I did with the move and what you have will fit, but... 10g onboard is a joke, because it is all CAT6. If you want to go that route, take a tip form your name and go Enterprise with it; SFP+/Fiber is superior to and cheaper* than trying to run 10g CAT. The Aqua has an extra X4 on the bottom you can use for networking and the storage you have now is not likely to bottleneck the Chipset link thanks to 4.0, so its fine. All that said, Zen 3 is this year. If you can not wait, the Aqua should still be able to handle an upgrade, but knowing this, does a 3950X make sense? The 2990WX may still catch a good price, but the moment Zen 3 is out the 3950X is going to bomb just as hard as the 2700X and 1800X did in the used market*. The question is how long you want to wait. I'd consider the Aqua and a cheaper chip, maybe even a used chip, to be replaced with Zen 3 later this year. Then you get to scratch the itch twice and may even break even financially if you find a good buyer. *Opinions based on US Used market. I am aware that used market in other places can be dumb.
