New iOS devices usually mean new processors, and sure enough, Apple hastaken the wraps off of some fresh silicon. The A9X in the iPad Pro is a doozy, packing up to 80 percent better performance than the A8X from the iPad Air 2. It's a champ beyond raw computational power, too, with twice the graphics and storage performance as well as double the memory bandwidth. Supposedly, the A9X is more powerful than 80 percent of portable PCs released in the past year -- that's a bold claim that we'll want to verify for ourselves, but it's certainly promising.
