Your first link prices per chip makes it look like it's about 71 chips per wafer for 5nm at $238 per chip. If we get the same number of chips per wafer at 2nm, that's about $350 per chip.
- alberth 3y agoThe cost increase is the same, on a % basis, regardless if it's per chip or per wafer. Size Cost/Wafer % Difference ==== ========== ============ 5nm $16,988 2nm $25,000 47% It's a 47% increase in Cost/Wafer from 5nm to 2nm Size Cost/Chip % Difference ==== ========== ============ 5nm $238 2nm $350 47% It's the same 47% increase in Cost/Chip (as it is for Cost/Wafer).
- grumple 3y agoI'd hope so, because I calculated the 350 from the other 3 numbers xD
