The price of the 4080 has nothing to do with all that, imo. I think the price comes only from the fact that a huge amount of 30-series stock is still in stores due to the mining crash, which Nvidia didn't expect. If they sell the 4080 any cheaper than they currently are, it'll only be a guarantee that 30-series stock will never move. Any further 40-series card released will only cut into profits coming from 30-series cards.The node Nvidia is using is essentially 5nm+, same as how TSMC's 6nm is just 7nm+. If it does cost more, it's likely a very small amount. Otherwise it's not really worth it. Akin to TSMC 6nm, the density increase is extremely small with the upside that it's compatible with 7nm. In essence Nvidia could have taped out for 5nm and the design would have been compatible with TSMC's 4nm.
Here's TSMC's page for the 5nm which references 4nm: https://www.tsmc.com/english/dedicatedFoundry/technology/logic/l_5nm
4nm doesn't have it's own section due to the reasons stated above and on TSMC's website.
Yes, the 5nm price estimate were in the $16,000 - $17,000 range. Current estimates at over 2 1/2 years later place that at around $10,000.
As you pointed out, even under the most generous circumstances it's hard to explain the price of the 4080.
