IPAD PRO

iPad Pro design

Design-wise, the iPad Pro is a companion piece to the iPad Air 2: you're just getting a lot more iPad. Its general layout, its material, edging and so on all match. The positioning of the buttons, the Lightning and headphone ports, the Touch ID-equipped Home button: all of these are the same as on the smaller iPad Air 2. But there are some key differences to the design.
These are not cosmetic differences. Each one corresponds to something that the iPad Pro does differently.

There are four speakers - resulting in far more volume output and (Apple claims) automatically reblancing audio performance.
There is a new connector on the side of the iPad Pro: the lefthand side if you're holding it in portrait orientation. Apple calls it the Smart Connector. This is for the new Smart Keyboard accessory.
Lastly, and probably most importantly, the screen's design has been enhanced. This isn't something that you will be able to notice from the exterior hardware, but Apple is confident that you'll notice is when the device is in use.

screen size and resolution

The iPad Pro features a 12.9-inch (diagonal) display with a resolution of 2732 x 2048. That gives a pixel density of 264.68, that's the same density as the iPad Air 2 across a far larger screen, and a total of 5.6 million pixels.
Apple boasted that the iPad Pro has more pixels than the 15-inch Retina MacBook Pro.

The iPad Pro offers 78 percent more screen space than the iPad Air 2. Its width is the same as the iPad Air 2's length, which makes it easy to run apps optimised for the smaller device in portrait, with the Pro in landscape orientation. Running two side by side would work well, too, thanks to the Split View in iOS 9.

 Processor

The iPad Pro's processor chip, as we expected, is the A9X: an update to the A8X chip in the iPad Air 2 (which is itself very fast, in our experience).
Apple boasted that the A9X chip offers 2x the memory bandwidth of the A8X, and 2x faster storage performance too. Overall speed is 1.8x the performance of the A8X, Apple says, although we'd like to run our own tests.
One last (two-part) boast about the iPad Pro's speed. Apple reckons that in CPU tests, the Pro is faster than 80 precedent of portable PCs, and faster than 90 percent in graphics tests. We'll update this article when we know a little more about the details of Apple's testing!
Here's Apple press release on the iPad Pro's speed:
"iPad Pro delivers groundbreaking performance and energy efficiency, so you can tackle the most demanding tasks. Apple's powerful new 64-bit A9X chip, with third-generation 64-bit architecture, provides desktop-class CPU performance and console-class graphics."
