The 7900, for example, with PBO is essentially the same as the 7900x at stock. Same thermals, power draw, and performance. You could get the 7900x and put it on eco mode and it would be the same as the 7900. Or, you could get the 7900 and boost it with PBO and it would be the same as the 7900x. There does seem to be some difference with some apps, e.g. in Adobe Premier, the 7900x performs better than 7900 with PBO. The pricing is fairly close right now.

Bottom line: when choosing between 7900x and 7900, get whichever one is cheaper.
 
Twice as efficient as a 7900x and 3x as efficient as a 13700k while still performing competitively.
The 7900 should easily dethrone the 5950x as the most efficient cpu at stock settings. I dont see Intel approaching anywhere near this even after they launch their non-k cpus.

It would be much harder for Intel to cut power consumption in half since they are already leveraging the low frequency e cores.

The 12700 (non k) would likely need a 6+12 or 6+16 configuration instead of 8+8 with p core clocks reduced on top. This would likely take a significant performance hit in certain applications.
 
How much faster is 7900X+PBO than 7900+PBO? Hmm...

Also, how do people account for the node efficiency improvements? I bet the 7900 gets a (small) free ride solely on the 2 months since the 7900X got released. A 5600X sold today performs quite a lot different than a 5600X sold two years ago.

PBO doesn't really do alot for the 7900x. There no node stepping changes as far as I know. The 7900 is just set up from the factory to be efficient at stock with the ability to easily turn on PBO to have it perform on par with the 7900x. The 7900x could easily go the other way with an eco mode but maybe it takes some more user input?

Bottom line, the non x versions displays to thr masses just how efficient zen 4 can be and the prices of these cpus are effectively lowered which is always something to get excited about.
 
questioning the need to upgrade the barebones I currently have (5600G, mitx AM4 mobo, 32gb ddr4 --> 7900, mitx AM5 mobo, 64gb ddr5)... but you know how the upgrade bug goes, hah.

Right now is a great time to get a 7950X, 7900X, 7700X, or 7600X - people are either not buying to wait for X3D, or selling to wait for X3D. Don't sleep on the used and secondary markets. I just got a 7900X used for $300 (even Amazon has it new for $420 - so no Micro Center nearby required!) and I will be selling my 7700X for a low price once I swap it out. Plus, once you've invested at that low price if it turns out X3D is all that everyone thinks it will be, it's easy to break even to make the move.

With all that said - the mobo is really the hard part. If you have a Micro Center nearby they have clearance/closeout ASRock Taichi X670E boards for $32x.xx that are listed as open box but I believe are manufactuer refurb (likely from the RAM residue incidents at launch). I got one a few weeks ago and it has been awesome!

What is your use case?

1. Wow what a deal!!! $300 for 7900x, you simply just swapped 7700x cost with 7900x.
2. Machupo will definitely look for itx board as his is barebone PC to begin with, but agreed that Taichi X670E at $32x.xx is quite a good deal.
