I think the 7800x3d is coming January and that is why AMD releases 7700x instead 7800x. makes sense. I doubt the entire lineup will get the 3dv cache upgrade.
i only hope the 7800x3d will not have lower frequency like the 5800x3d had.
I wonder if the 3D 7x00 models will only offer around that 10% performance gain (on average) over it's non-3D counterparts, much like how the 5800X3D out performed the 5800X at 1080p and 1440p resolutions, or offer more/less?
A leaked slide shows AMD's own internal testing of A0 Zen4 silicon and A0 Zen4 Silicon with 3d v-cache shows that the improvement by the additional cache averaged around 25%-30%. So, if that holds true with the final silicon, Zen4 with v-cache should be the fastest gaming CPUs, even faster than raptor lake, but we'll see.
The fact that 3D-Vcache CPU make this whole release a bit underwhelming and most people should just wait until 3D-Vcache get released. It might be expensive, but it will perform, and there are good chance other CPU will be much cheaper.
I'm well aware that as 5800X3D demonstrated, there's no significant improvement except game, and often regressed in some app. My speculation IPC and clock speed hindered them, therefore AMD looks confident as evidence by their EPYC V-Cache line up, and as rumor has it not just 8 cores variant, 12 and 16 cores also receive special treatment as well.
If you're a gamer, you should only be buying the v-cache versions of AMD CPUs moving forward. Unless you purposely buy games that don't benefit from L3 which would be very odd. Enough games benefit from L3 for it to be a worthy purchase, at least that's what I concluded from Hardware Unboxed and TechPowerUps reviews of the 5800X3D.
If the 3DV are pumping out to 30% higher performance than their stock variants (rumored), it will make them really hard to pass up. I'm trying to hold out till Zen 5, but these rumors sound so damn good. I can't wait till my trusted outlets get these in hand to test.
The benefits of 3D V-Cache comes down to very specific edge cases.
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.
I’m sort of in the same boat. Whenever it is that you do a build, we’re going to need to know about it — I’ll be most interested in your heatsink and fans choices.
I might probably do the same as you guys. I was thinking going for Arctic Liquid Freezer 420 for the CPU cooler. Either 7950x3D or 7900x3D depending on the price, but I am heavily leaning to 7950x3D already.
You mean 30% more than stock zen4, even if just for games? yeah that's not happening unless it can also do DDR5 9000 with some magic crystal dragon balls
I had to laugh at that, Vegeta is dude though! Anywho, I'm just going off what the rumors are saying in gaming. If it isn't and its like 10%, I'll just wait for Zen 5 like I was going to do anyways. Priority at the moment is 7900XT or 7950XT then I'll be looking at the v-cache chips if they are indeed 30% faster. I need all the powers for high refresh 4K gaming at max settings.

I had hoped for a 5950X3D to hold me over...but that 7950X3D is gonna kick ass. WCCFTECH is talking about 90c temps, that makes me a bit nervous. I hope they got some bad intel (no pun intended).
Dude I have a mindset from a i5 2600k. That's 11 years old processor.
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.
Not necessarily too much power but rather too much money. I have thought about it myself.
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.

While Sandy Bridge was a good design serving well for many years, you will notice a huge difference in performance with these new chips. Even Sandy Bridge -> Zen 3 is very noticeable, so Zen 4 will be even greater. Also, a high TDP desktop CPU will be performing much more consistently than a laptop, so you'll notice a difference here too.
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:
Since you are using docker a lot, I hope you have explored using a dropdown terminal and possibly tmux. Once you've gotten used to it, there is no going back.

Actually I do use the SublimeText as well, just not full time for development, IntelliJ/VsCode is for that. SublimeText is sometimes for that but mostly for general text editing. And as you said, it doesn't have a lot of plugins for development, and that's a no go if I were to make it a first class citizen and my primary IDE. Because it clearly is not an IDE, but rather a text editor, nonetheless I still use it.
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.
