While my ST only saw a 120->126 score going from jedec 4800 to fast tuned ram, MT sees a much larger gain. I'll run it real quick for reference.
I went over a couple of detailed reviews of Raphael CPUs where it was shown that the effective clocks in ST load like SuperPI for the two best cores reached 5700-5750 MHz at stock and 5850 MHz with +100 PBO boost and a tuned curve, with Fmax 5850 and 5950 respectively. Looks like something is really wrong with the setup where the ST clocks can't exceed 4650Mhz.
The rate at wich the score increase as he increase power, we ll know more once Computerbase do their review since they ll make tests at 45, 65, 88 and 142W like they did for the 7950X.
Yes, we'll know for sure, although I was asking why you assumed that the VRM voltage is held at a fixed value, while the telemetry indicated otherwise.

It runs 5650 in CB 2024 ST. In other singlethreaded workloads, it can 5700 or 5750. FMAX/peak reported frequency when unloaded hits 5850.

The updated design was introduced by Mark Papermaster, AMD's chief technology officer, and he began by pointing out that the changes culminated from its collaboration with Samsung, which licenses AMD's graphics tech for the Exynos range of smartphone and tablet processors.
That's very interesting (emphasis mine).

Cross pollination of technologies between smartphone and PC!

If it’s N4X that’s even better, as it’s meant for extreme performance and no wonder AMD is able clock highly so easily.

One could say N4X is better than N3B for desktop.

Not exactly. Hardwareluxx (Andreas Schilling) wrote "N4P and N4X".
Andreas Schilling said:
The new CCD is supposed to be [manufactured in] "TSMC 4nm FinFET" — at the tech day, N4P and N4X have been mentioned specifically.
PS:
The article from which this comes from is centered around questions which Hardwareluxx asked AMD after the Tech Day. Especially, they asked about manufacturing. The way how the article is worded, it is evident that AMD answered this with "TSMC 4nm FinFET", whereas the "N4P and N4X" bit is only something which Andreas Schilling claims to have heard at the event.
Edit 2:
Further down in the article, he associates N4X with Eldora and N4P with Strix Point but we have no way of knowing what's fact and what's mistake if not invention (by the listener or by the speaker).

The conspiracy is always so laughable. X doing this because they don't want the Y to know.

Standard x86 projects span 5+ years. There are hundreds employees changing places each year. There are entire teams focused on "projecting the market competition situation".

Slides having a different number a few months before the launch won't matter.

The only variable thing is pricing, the rest is known.
