At Bernstein's 23rd SDC in London $ARM could sell more CPUs today if TSMC could manufacture more wafers for them. Why Intel Foundry Was Dismissed? Management's concern appears to be less about technology specs and more about execution risk. Building an advanced semiconductor product requires far more foundry support than licensing IP Intel Foundry was viewed as lacking the level of customer support and advanced-node manufacturing experience required for a first-generation CPU program. The argument is: Apple Can work with almost anybody because Apple already has: World-class silicon teams Manufacturing expertise Decades of experience ARM Is launching its first internally developed CPU. Therefore it needs a foundry partner that: Has mature workflows Has proven support teams Has extensive advanced-node experience Management reportedly believes Intel Foundry doesn't yet offer the same level of ecosystem support as TSMC.
