Apple has built many second-source partners for cost-reduction for a long time. But most of their CPUs are made by TSMC right now.

I'm wondering will Apple find another semiconductor factory partner (they tried to build A9 by both Samsung and TSMC, but Samsung one seems like has heat issues)or stick with TSMC?




Are there any fabs that can compete with TSMC? Or EUV equipment manufacturers that can compete with ASML?


from density (MT/mm2):

TSMC 5nm: 173.1

Samsung 5nm: 126.5

Intel 10nm: 100.8

Intel 7nm: 202 (estimated [1])

Therefore TSMC is still the best in density right now.

Wonder if Apple would buy TSMC


Taiwan would never let go of their golden goose.
