AMD Ryzen 7000X3D Series Reveal by CES 2023?
We already know that AMD is working on a variant of the "Zen 4" CPU complex die (CCD) featuring 3D Vertical Cache (3DV-cache) memory, through company roadmaps, and AMD even confirmed to us that the technology continues to be a part of the client roadmap of the company. We're now getting news that the first Ryzen 7000X3D ("Zen 4" with 3DV cache) processors could be unveiled by the 2023 International CES (January next year). It appears like while the conventional Ryzen 7000 series beats the 12th Gen Core "Alder Lake" at gaming, it might trade blows with the 13th Gen "Raptor Lake," and AMD will count on the 3DV cache technology to give it a competitive edge.
Greymon55, a reliable source with AMD leaks, hints at the possibility of three 7000X3D-series SKUs: the Ryzen 7 7800X3D (8-core/16-thread) positioned above the 7700X; the Ryzen 9 7900X3D (12-core/24-thread), and the Ryzen 9 7950X3D (16-core/32-thread). Older reports suggest the 3DV cache on these processors will be a generation more advanced to keep sync with the on-die L3 cache of the "Zen 4" CCD, and the L3D (the die on which the 3DV cache is located), will likely be built on the 6 nm process.

In 1440p we are talking ~7% and in 4K a massive 1%, and even in 1440p the results are mainly skewed by a few outliers. If you eliminate the outliers, then we're talking about ~1-2%.
So no, it's not significantly better, and in CPU tests 5800X3D actually slightly slower than 5800X overall.
Thinking that extra L3 cache will contribute an extra 30% performance overall (either everywhere or in just gaming) is beyond ludicrous. L3 cache doesn't work like L2, it's a spillover cache for L2. Lots of instruction cache hits in L3 is a typical symptom of poorly written code, so it's not something to strive for.
X3D is pretty awesome and would love to see a 7950X3D released within 4-5 months.
Truth be told I also have a work Macbook pro with a i9-9980HK processor as well as a Linux work laptop with a 12700HK processor, but still these are laptop processors designed with limited TDP and power envelopes unlike the desktop processors.
I want something truly amazing, I also need it as I do software engineering and having a lot of dockerized microservices running with a lot tabs in chrome plus multiple instances of IntelliJ and/or VsCode, as well as running testing suites after doing development and wanting to see my new code doesn't break something.
This will easily use those cores as well as at least 64 GB memory, which I plan to get. This will be ultimate workhorse at home.
Also when you compare cores vs cores and SKU vs SKU and taking OCing into account, threadripper platform is much more expensive than AM4/5.
And to be honest I don't think I would utilise the 32 or 64 cores even if I were to get them.
So in that regard the desktop 5950x or 7950x is perfect in here. The 3D-V cache variant is even better as it performs better in games (which I don't really care much about) but also other business and scientific workloads which I like a lot.
So 7950x3D would set me for about the next 5 or so years.
Having a very responsive CPU essential for having a good development experience, even more-so than core count. The amount of VMs or dockers you will be running should dictate the core count you need. Your IDEs/text editors will also benefit from faster CPU cores, but be aware that VsCode will always be laggy. If you want to get something more responsive you should explore alternatives like SublimeText (yes, I know it's not free), which is much more performant, but may not have all the plugins you want.
When it comes waiting for Zen 4 with 3D V-Cache, the indicators we have from 5800X vs. 5800X3D indicates that it may not help development very much, at least if we are to look at Java-performance and even Visual Studio(even though this doesn't fit your software suite). But this gives an idea that sacrificing clock speed for more L3 will likely not help. It also shows that Alder Lake is much more powerful in such tasks than Zen 3, so this is something to watch when we get to see Zen 4 vs. Raptor Lake, and if Intel still have a significant lead then, you should consider them for this particular workload.
OT:
As for tmux, I do use a similar thing, it's iTerm2 with zsh and oh-my-zsh with its plugins.
As for the Zen 4 vs. Raptor Lake, I definitely plan to watch out for the reviews and will go for whichever platform turns out to be faster for my use case, that's for sure. It's not like I am definitely set for 7950x, I am certainly open to options. It's just that I have a feeling that 7950x might be it, and I will change my opinion if reviews challenge that for sure. I am no fanboy and don't care for that nonsense.
