You only have to look at the i7-7700k preview
just published to see that even Intel cannot make any progress worth mentioning with the materials and technologies available at the moment.
This does give AMD a chance to catch up, so to speak. If they can deliver Broadwell-E performance for a lower cost, they just may have a chance at taking some business from Intel. There are a lot of people interested in CPUs for games machines that don't like wasting silicon budget on a worthless GPU.
I can see them getting tripped up on frequencies though. Broadwell IPC, but clocks that can't match Intel's parts would put them in kind of a shitty place. Good luck to them.
