Apple's A12Z Bionic chip that debuted in the new iPad Pro last week is probably a rebranded A12X Bionic processor from 2018 that activates a previously disabled graphics core.
Apple on Wednesday, March 19, 2020, announced refreshed iPad Pro models with the in-house designed A12Z Bionic chip, wide and ultra-wide rear cameras, a LiDAR sensor for scanning your environment in 3D and other new features.
Apple today refreshed its flagship iPad Pro models, bringing even more pro features such as a two-lens rear setup that includes wide and ultra-wide cameras and, for the first time in any Apple device, a sophisticated LiDAR sensor that can map your surroundings in 3D. The company also unveiled a new Magic Keyboard accessory designed specifically for this new iPad Pro that features a floating design, backlit keys and a built-in trackpad which lets you perform Multi-Touch gestures to navigate the entire tablet without ever lifting your hand.
