Just imagine what intel will do with amd when they get to 7nm
I'm yet to see actual products or announcements from Intel on that end. They did hire the most qualified person for the job, but it still gets very awkward. Intel has a great lead in clock speed because they used and improved over the same node for generations. Don't expect their clockspeed to carry over to 7nm, they'll compensate with IPC just like AMD does.
Intel throttles horribly on laptops, it's only a matter of time for them to also do that on desktops (it's already more or less the case as reviewers use out of spec boost motherboards and exotic cooling for it).
I'm out of the loop with CPUs - do we know why Intel is still on 14nm?
Intel had no interest in taking larger risks until AMD released, and they had continuously larger requests for 14nm. At the same time, they also had very hard goals on 7nm or 10nm to make it worth their while, but they didn't found clock speed and yields to come close to reasonable margins. 7nm also meant they had to switch to EUV, and only lately did they finally reached a convenient place for it. They made a few 10nm chips, fulfilled their order, then stopped. They also had to change a few fabs from 10 or 7nm to 14nm, to make more 14nm chips to keep up with demand. They had very poor planning on a few fronts, and they keep pushing 7nm further: last announcement, it was ~2021.
Since 5nm was in risk production at TSMC for a long time now, it's fair to expect AMD caught up on the process node, and it's gonna be a fair fight from now on.
