Unless this can be extrapolated from the text (mentioning it's a superset of N4P), there's no mention of electrical performance. So it's probably safe to asume it's no better than N4P, but hopefully not worse neither?
Focus is elsewhere, but they would not take any major downgrades. I assume it will be single digit in any direction. it's almost always a tradeoff, so C, most likely mean noticeably cheaper and faster production, less defect due to less complicity, but raw power draw is likely not much changed.
Guessing, but I think "C" processes are allowed to be worse performing than "P" process of the same generation, even if they come out later. In some cases, the improvements may result in better performance, but the selling point is cost. My understanding at this level is admittedly limited, but I think the cell library's main selling point being area optimization means that there's some stuff in the P process that will perform better at the cost of more area.

I suspect it's a little bit better.deil - Monday, April 29, 2024 - link

Interesting in light of rumors that AMD will make some products such as "Sonoma Valley" on Samsung 4nm.Anymoore - Sunday, May 26, 2024 - link
It's implied yield is still a concern? "better yield from area reduction"
