@Panos If you reinforce the TDP limits, Skylake-X can be pretty efficient: https://techreport.com/review/32607/intel-core-i9-7980xe-and-core-i9-7960x-cpus-reviewed/13
A lot of reviewers tested with X299 motherboards which don't enforce TDP, and of course when overclocking perf/W is thrown out the window.
@Madpete TSMC's 7nm should enter HVM earlier than Intel's 10nm, so there's going to be a period in which AMD will have 7/10nm class products out while Intel doesn't. It's going to be interesting to see how much of an impact that will have on performance. Gamers Nexus has a video with David Kanter on Intel's 10nm, their delays and how it would compare with other foundry 7nm https://www.youtube.com/watch?v=dtiBEHH7mEA it's an interesting watch.
