A powerful upgrade is on the cards for the entry-level iPad, according to Evan Blass. The current 10.2-inch tablet has the A10 Fusion chipset from 2016's iPhone 7 series, but the 2020 edition could see a jump to the A12X Bionic. Excess stock may be the reason for bringing the former-iPad Pro chipset to the 8th generation iPad, which should be compatible with the Apple Pencil and Smart Keyboard too.
