Let’s rewind to 2013 and the A7, Apple’s first 64-bit chip built on TSMC’s 28nm process. At the time, those 28nm wafers cost Apple $5,000 each, according to Creative Strategies CEO Ben Bajarin’s supply chain sources. Those wafers packed a billion transistors into the A7’s dual-core CPU and quad-cluster GPU.
Apple’s 3nm TSMC wafer costs soar to $18,000, more than tripling since the 28nm A7 chip
