The 10.5-inch iPad Pro devices feature a fully-laminated, antireflective 10.5-inch LED-backlit 2224x1668 (264 ppi, DCI-P3 color gamut) touch-sensitive "Retina" display. These models support a new "ProMotion technology" that provides an impressive 120 Hz refresh rate for smoother animations and lower latency when using the Apple Pencil accessory.
The 10.5-inch iPad Pro models are powered by an Apple A10X processor, have 4 GB of RAM, and either 64 GB, 256 GB, or 512 GB of flash memory storage.
Other noteworthy features include dual cameras -- a rear-mounted 12 megapixel "iSight" camera capable of shooting stills and 4K video and a front-mounted 7 megapixel "FaceTime HD" camera capable of shooting stills and 1080p HD video and Bluetooth 4.2, as well as dual microphones and two sets of stereo speakers.
Connectivity to computers, if desired, and power is provided by a Lightning port. A "Smart Connector" provides connectivity for a device-specific small Apple Smart Keyboard. Additional input also is available courtesy of an optional "Apple Pencil", which provides a variety of pressure sensitive sketching and drawing options.
