PCMAG: Every year about this time Intel releases a new set of processors on the scene, with a laundry list of improvements over the previous generation. This time around, it's the fourth-generation Intel Core processors (codenamed Haswell). But that doesn't mean that last year's third generation Intel Core CPUs (codenamed Ivy Bridge) is going away.

We break down that has changed (and what hasn't) between Haswell and Ivy Bridge.
