AMD Ryzen 7000X3D is not overclockable, however will support for PBO 2 and the Curve Optimizer
Over the weekend, AMD made an error on their product pages, suggesting that the upcoming X3D CPUs could be overclocked. That is not entirely correct.
The product page for the AMD Ryzen 9 7950X3D had previously displayed an error stating that the processor was "Unlocked for Overclocking." However, the manufacturer quickly corrected this information and removed it from the product page. However, let's recap what the processor can do tweaking-wise. The three upcoming Ryzen 7000X3D processors, the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, will not support manual overclocking of the Zen 4 processor cores. However, they will include the Precision Boost 2 and Curve Optimizer features, which were not supported by the previous Ryzen 7 5800X3D processor.
Next to DRAM overclocking, the Infinity Fabric is still tweakable via the BCLK and may be done manually or with pre-made EXPO profiles. In general, there is little room for further optimization with layered L3 cache on X3D CPUs.
AMD just posted the following:
"Ryzen 7000X3D Series processors are unlocked for memory and infinity fabric overclocking, just like Ryzen 5800X3D. New to the 7000X3D, we have also added PBO and Curve Optimizer capabilities - AMD"

Review: AMD Ryzen 9 7900 processor - 01/09/2023 04:00 PM
AMD also released a Ryzen 9 7900; this 65W non-X model offers absolutely beautiful performance and temperatures. Next to the 7700, this actually might become a best seller in the current Ryzen 7000 pr...
Review: AMD Ryzen 7 7700 processor - 01/09/2023 04:00 PM
We check out AMD's new non-X Ryzen 7 7700 series 8-core processor, and it impressed us far more than the original X model. The newer version's performance is superior, and its thermal design power (...

Suffering from excitritis as well. Well, more than regular.
Still hanging on to a (r)aging Intel 2600k though. So perhaps I could wait just a little, little bit until the reviews come out. Done that for over 10 years now
or is it 11 or 12 
Well, you're in for a treat. Going from an i7 920 x58 to the 3800x and x570 was an amazing upgrade!
I just built a new gaming rig a couple weeks ago due to wife in need of a new pc. The timing couldn't have been worse. I was looking at the 13700's and 13900's and they do perform quite well. But as a 1440p gamer also in need of a gpu upgrade I went with the AM4 platform using the 5800x3d. Wish I had the budget for the AM5 but the pricing was just out of the budget. It's all good, my 5 year old will get the 5800x3d rig in a few years.
I've had Intel and AMD gaming rigs over the years. The 3800x has not dissappointed.

There are very few work applications that benefit from all that extra cache.
The only people that should care about these 3DV cache parts are gamers.
Oddly enough, it's almost the opposite on Linux. In any case, your underlying point remains valid: these CPUs are only worth getting if they improve the workload you put them under. While it'd be nice to have the same OC capability, I'm guessing most people would quickly find out that they're not going to benefit much from doing so when the chip keeps thermal throttling.

i think its worth mentioning that the boost limits of the 7950x3d 7900x3d are still 5.7/5.6ghz doubt that you'd ever hit or exceed that with a boost override on the 3dvcached die.
only product that seems to be badly nerfed by the lack of overclocking is the 7800x3d.
though if your board has eclk support it wont stop you like the locked multi on the 5800x3d did.

Well only the CCD without 3D cache overclocks that high out of the box. But you are right still.
edit: I'm wondering... does AMD allow you to overclock the CCD with 3Dcache and the CCD without it seperately?

reality check - we're nerds.
in all sincerity PBO and IF tweaking will be a larger part of "OC" performance than doing a bclk over ride for a vanishing percentage.
that said, it doesn't mean i wouldn't want to do it (Nerd!)
imho, i think AMD is being immensely conservative knowing the large number of people looking to create content re:hardware.
the proof will be in the pudding and i can't wait for my 7900X3D. i know there'll be several gurus w/7xxx3D.
on another note: the VRM overkill on B and X AM5 mobos makes me very disappointed as i thought some of that grunt could be used for OC'ing the 3D boys. it seems they went hog wild (10+ phases) just to hike the price. i seriously chose one mobo because it had the beefiest VRM's @ price (B650)
