Zerene Stacker's speed for a PMax stack with the same set of 200 images 24MP each on different Ryzen CPUs:

Ryzen 2700x: 6min16s
Ryzen 3900x: 5min42s
Ryzen 3950x: 4min54s
Tested my CPU, it took 10min10sec to complete a PMax stack (and alignment), and 6:35 if they are already aligned.
So there is obviously plenty of room for improvement. Would it be possible to say how much quicker than the 3950x the newer Ryzen5000+ chips would be? I assume something like 20-40% faster? Or is that too optimistic?

The 3950x has 39247 passmark multithread points. The 5950x has 46130 passmark multithread points, which is 17% more. So I think you can expect a speed improvement of 15-20% when you compare the 5950x to the 3950x. personally I would get a used older gen-one. If you compare the speed per euro or dollar, the new onces don't makes sense. They are probably 15-20% faster. The 3950x is 668 euro in The Netherlands. For comparison, the 3900x is 445 euro (33% cheaper and only 16% slower). The 5950x is 898 euro, which is 34% more expensive and definitely nowhere near 34% faster.

I have just updated the Graphic card, switching from GTX 1030 to a TitanX.

The tests results are indeed quite better under HF.
Now the "100 files" performance test gives: 3.63 seconds (578.71 Mpixel/s) with transfer speed 11789.21MB/s.
In fine, this is confirmed: the graphic card does a huge difference.

I hope this will helps.
Regards

Pierre

Indeed it does. It just has to be relatively fast before it starts to take over the benchmark. Mine helps only a little. If maximum speed is required, that is achieved by investing in the graphics card.
