The funny part is, those are Zen 3 numbers. If Intel had opted not to create a hybrid CPU, but rather, had focused on efficiency, they would have had their own '5950x'. It would have been slightly worse thanks to a slightly worse process, lack of chiplets, and a garbage interconnect, but they could have sold people like me one thanks to sane power consumption.
I do happen to know for a fact Intel 7 does not cost Intel anywhere close to $9,000/wafer. Note that my number includes everything, including R&D. Intel's number for Intel 7 is close to half of your number, FWIW. I can't disclose much, but if you think I am wrong, just look at the 'margins' section of the earnings report. You, as an end user can easily calculate the number of dies per wafer, and therefore guess as to whether what I say is accurate. A typical split on a manufactured product is 33% manufacturer, 33% distributor, and 33% retailer FYI. Take from that what you may.
EDIT: I did want to add one thing here. I don't expect you to believe the above statement because I am a random internet person, but TSMC N7 originally launched at around 10 grand a wafer. Look at TSMC's margins and do the math from there if you don't. If you doubt the 10 grand number, just do some Googling. Intel's costs are lower than TSMC's, and total margin required is significantly less.
Good night.
