Clearly! I don’t know if I’d say it’s “on par” if an Apple A-series part (i.e., low power enough to be shipped in iPhones and not in any of their “serious” computers) is actually getting slightly higher numbers than the fastest, most power hungry core that AMD has right now!

It isn't. The A17 Pro gets 7199 on GB6 multi-thread compared to 18778 for the 7950X, and multi-thread workloads are the only thing that will cause the 7950X to use its full TDP. If you give the Apple chip a desktop's power budget, the single-thread number barely changes because that isn't what sets the TDP.

And Zen4 is punching above its weight because it's on TSMC 5nm compared to the A17 Pro on TSMC 3nm. Try comparing the chips that use the same process.

I dunno, I haven't seen much evidence that 3nm is as big a leap as hoped/claimed, the A17 pro is certainly impressive but in most cases it is not more efficient for its power gains.

But how many cores does the A17 have versus the 7950X?

That's kind of the point -- the reason it uses more power is that it has more cores, out of which you get higher multi-thread performance.
No, that is clearly not the case given that the TDP of the A17 Pro (10W) is 17 times less than the TDP of the 7950X (170W) while the multi-core performance of the 7950X is only 2.6x that of the A17 Pro.

The reason it uses more power is that it's less efficient. The reason it has higher multi-core performance is that it has four times the number of cores.

Exactly. If we have to explain this in every single discussion we may as well not discuss it.
AMD Ryzen 9 7950x: 16 cores and 32 threads

Apple A17 Pro: 6 cores (4 efficiency and 2 performance)

Yeah, I don't care about power consumption.

There is no 'serious' computers coming out of Apple for quite some time now - just glorified consumption devices :)

Can Apple sillicon run Dota2@200fps or Visual Studio (Not CODE!) 2022+ as good as an x86? Can I put a 7900XTX on a Mac and run Windows natively ?

Interesting that you‘re writing about serious computers followed by referring to running games at 200 fps. It seems like you yourself don’t know anything about actual “serious“ use-cases.
There is nothing more serious than gaming.
Sure.
