How much of a jump is a dual core HD 4000 to a dual core HD 4600? Same question for a quad core? Now how much of a jump is a dual core HD 4000 to the Iris 5100? And how much is a quad core HD 4000 to an Iris Pro 5200? The answers to these would determine in my mind whether Apple is waiting for Broadwell.
