For info, around 600 A13 chips fit on a 300mm wafer. Means Apple is paying around $29 per chip.

- npunt 6y agoA13 is 98.5mm2 & 8.5BTr, so ~86MTr/mm2 density, a bit lower than what chart estimates [1] (95MTr/mm2 for 7nm). A14 might be a significantly smaller chip since its 11.8BTr / 171MTr/mm2 (chart estimate) = ~69mm2 size [1] https://en.wikichip.org/wiki/5_nm_lithography_process https://en.wikichip.org/wiki/5_nm_lithography_process

- greenknight 6y agoApple may be paying just for working chips, rather than wafers.
- futhey 6y agoIf you're their largest customer, and there are no alternative suppliers, leverage works both ways -- but it's beside the point. TSMC does multi-year low-scale runs of new processes to figure out tooling and reduce errors, before committing to huge orders.
