Note: Resurrecting the thread for AMD 9800X3D CPU now that the reviews for it are out. The thread has lots of still valid advice and discussion about performance in Stellaris and creating new thread seems unnecessary as performance is rather limited topic.
Gamers Nexus and Linus Tech Tips have Stellaris in their 9800X3D review and seems solid performance increase over 5800X3D and 7800X3D - though I would not consider upgrade from 7800X3D to be worth it. It also includes other CPUs: Ryzen 9000 series very competitive. 9800X3D has other advantages of course, especially over 5800X3D - most notable being much improved performance in productivity stuff besides games (check for example Techpowerup review for that).

Yes, this 500€ cpu will now take the crown for Stellaris. I have a 7800x3d running atm and really want to skip this generation. I think the ones from next year will be good to finalize the am5 platform for me.
And still, it is not the raw speed for me that is not good in the current situation. The game runs fast enough even into the late 2600s, but the daily tick stutter is there literally after 30 years of playing. As soon as you know it will be there you will notice it. And it get worse with every year played...
I play on a computer with basically "unlimited" resources in every other game, these lags just turn me off very, very quick while playing. Why should I look at a spread sheet diashow when other, super eye candy games run fine and well on my pc?

I understand people who require fifty mods to enjoy the game seeing performance issues, but I haven't noticed meaningful late game lag in years.
Buuuuut I also always play with 2.5 tech costs so I don't get to repeatables until the end of the game because I like each tech to feel meaningful. This also means there are less pops in the galaxy and therefore fewer ships and buildings and megastructures and everything else, so could the much vaunted MP fave 0.5 tech cost be the cause of some of the lag problems people see? I play Admiral and do end most games before the crisis lands as once I can beat FE I know the game is done, but in games when I am weaker the 1 x crisis feels pretty balanced and threatening and fun. I'm probably just terrible at the game??

For those looking the highest performance for both gaming and multithreaded productivity software AMD released new 16-core 9950X3D CPU. 16 cores, 8 cores with x3D cache. Slightly lower pure gaming performance than 9800X3D but absolutely smokes 9800X3D in any sort of multithreaded software. And it's going to cost a lot.
16 core x3D requires usage of Xbox Game Bar so that the operating system can prioritize cores with extra cache for the games so it isn't as "fire and forget" as the 8 core variants.
From GamersNexus review as it relates to Stellaris:

Nice to see the thread brought to life!(resurrected? Necroed?) Yes I was also going to post that review. 9950X3D will be my next CPU.
However the whole point of the 4.0 revamp is to make the game not require modern monster CPUs - at least in theory - you mileage may vary.
Once the 4.0 becomes stable and they do the optimizations of the pop system let's post numbers here, along with huge pop game saves))))

How is the 9950x3d manufactured? Is it using the same x3d cache for all cores? If not, I would not buy this variant. The 7000 series had the same issue, where only the 7800x3d was really good for gaming.
8 cores with x3D, 8 cores without. Like I said in the post in Windows it requires Xbox Game Bar active so that the OS can schedule games to the correct cores. For pure gaming there is no point to get 9950X3D but if high performance for both games and productivity is required then 9950X3D is no-brainer over 9800X3D.
AMD has resolved the Core Packing issues. But it is also important how many threads the game starts, and if the correct bios/DLLs are active on your windows installation.
Have a look here, he discusses and shows exactly this issue being solved:
level1techs didnt provide a detailed breakdown for stellaris but mentioned that the 9950X3d ran 9.8% faster than the 9980X3d in a lategame galaxy
its still sad that those ultra-duper-super cores are only like 2x times better then old ones. For that price they should be 5x times faster.

the 9950X3D is cheaper in real terms than the 7950X3D at launch btw and is unequivocally a better product than its predecessor.

Totally agree, and it seems that the future will be NUMA in any way possible.
As said by others, let's hope the 4.0 delivers on performance improvements so we do not have to buy specific hardware to run our favourite game the way we want, For me that's a huge galaxy with loads of empires. Makes the galaxy feel alive and diverse.
I am very skeptical about them achieving the levels of performance that people want. Mainly because no other PDX game has been able to do it. Even in Victoria 3 your game will run terribly if you don't have decent hardware. I don't get why Stellaris will suddenly be different when it's running on a similar engine. I'm sure there will be a noticeable performance increase but I doubt it will reach the expectations some people seem to have. I saw some especially ridiculous expectations on reddit with people talking about 10k star galaxies with no slowdown. I am personally keeping my expectations modest and expecting no more than a 20-30% increase in performance.
I would personally be happy with 20% to 30%. As you say, there is only so much they can do with the engine.
So, sadly I have to pull up this threat with the 4.0 update and say: The performance is not better on my side. They daily tick stutter is still present and it drives me insane while playing. I am not even at year 2300 and I already start seeing it when moving in the galaxy view. This is played on a very good pc and at this point absolutely inexcuseable. I am happy to change things around or use some different setting to avoid this, but there is basically no support for this issue that gets reported basically since the ftl rework in 2.0.
Specs:
Amd Ryzen 7800x3d
64gb ram 6000mhz
RTX 4090
All drivers and Windows up to date after the mess that was Win11 24h2. This issue is now following me with three generations of my PC and I am 100% sure this is not up to my side.

Exactly what you mean by daily stutter? I am getting slight stutter if I am running at fast speeds (eg. fastest) when in galaxy view and moving around but I doubt there is much can be done to eliminate that entirely - especially at the speed which is meant to run the simulation fast as possible. Reducing simulation speed tends to reduce stutter, too, or least it make less rare.
Assuming you meant that, I admit I have never really paid attention to that as either I am running at fastest (with goal of having fast as possible simulation speed), paused or at slow speeds.
The early game simulation speed at least seems fine - though the true test is huge late galaxy with loads of empires and I don't have plans to run that any time soon.

The performance for the same galaxy sizes feel the same between 3.9 and 4.0, I straight up observed both and you can already feel the slowdown at the 30th year, looks like we will have to wait for 4.1 :/

There is a small lag on every day tick which gets longer the more the save runs. Normally, after the 2300s the stutters become unbearable at larger galaxy sizes.
This video shows it pretty well, this is not pleasant to watch or play for me. There is no real slowdown for me, it just laggy and you can already see it after 50 years in, basically in early game.
