Apple launched its new iPad Pro family with A10X chipset at the beginning of June. Specifics on the chipset weren't confirmed back then, but we now learn it's built on a 10 nm process line by TSMC. The A10X's 10 nm FinFET process by TSMC appears for the first time in a consumer device. Until the WWDC on June 5, Apple's most powerful SoC was the A10, built on the 16 nm FinFET process. This allowed the size of the chipset to be just 96.4 sq.mm - 24% smaller than the A10 SoC and 34% reduction compared with the A9X. In fact, the A10X is the smallest chipset by Apple,...
