Apple's new iPad mini: How much better is it than last year's model?

On Tuesday, Apple announced the updates to this year's iPad mini. The biggest spec upgrades for the mini are the new Retina display on the 7.9 inch display and the new A7 64-bit processor, bringing both up to the level of the iPhone 5s and new iPad Air.

Apple now has an iOS device in each size category that runs its 64-bit version of iOS 7, something pundits think may be important in future app or software development.

So, how much of an upgrade is the new iPad mini over its predecessor? Besides the better screen and better processor, the new mini packs most of the same hardware as last year's model. It's even a touch heavier and thicker.

The new iPad mini with Retina display will start at $399 (16 GB) and the original iPad mini will remain on sale, starting at $299 (16 GB).

Take a look at our chart below comparing the new iPad mini with last year's model.
