These iPad Pro models are powered by the A12X Bionic chip, which still is a very powerful processor in 2020. Apple’s newest 2020 iPad Pro models include a LiDAR scanner and the A12Z Bionic, which is just the A12X with an extra GPU core enabled, to go with an extra camera lens. Not a huge upgrade by any means.
Refurbished iPad Pro models include a new battery and outer shell, along with a standard one-year warranty.
These usually sell out quickly, so if you’ve been waiting for a refurbished iPad Pro at $729, don’t hesitate to buy one.
