The 12.9-inch M1 iPad Pro could be a popular product amongst various customers, which is why Apple is reportedly ramping up production of its larger flagship tablet. Simultaneously, the company is working with TSMC, its chip supplier, to increase production of 5nm silicon as the newly announced iPad Pro also features the same SoC based on the same manufacturing process.

The ongoing chip shortage could put a dent in TSMC’s production if it does not ramp up wafer output. According to a paywalled DigiTimes report spotted by MacRumors, the chip manufacturer is expected to increase monthly output to 140,000 - 150,000 wafers, up from 120,000 wafers. With this increase, Apple could end up shipping around five million M1 iPad Pro units, and that is just for the 12.9-inch variant.
