Are we going to ignore the glaring issues with this "roadmap?"
In the real world, Whiskey Lake U launched and shipped last year. In this "leaker's" fantasyworld, Whiskey Lake U launched... a few weeks ago.

Same with Amber Lake Y. On planet Earth, Amber Lake Y was on the market in force, with the 2018 Macbook Air, during October of 2018. This "roadmap" however, would have us believe it hasn't launched yet. The CPU of one of the most popular laptops of one of the largest laptop brands on the planet, selling in their volume leader since last October, "launches" in a couple of months.

Of course, anyone with even a couple of brain cells to rub together already read the roadmap and saw this is really a roadmap for Intel's SIPP. Nothing to do with hardware - rather, it has everything to do with Intel's long term software support guarantees for corporate customers.

This is very much an Intel presentation. You must be quite new at this, because leaks had such "wavy lines" many times before.

It could also have been a simple mistake to call it U rather than H.

I have little doubts that its accurate. Of course, roadmaps can change. Doesn't mean that the slide is fake.

I doubt its accuracy: notice that in the top right corner, it's written "Rocket Lake U" instead of "Rocket Lake H". Notice also the little red wavy lines under the words "Kaby", "Mehlow" and "gfx", indicating a spelling corrector, which is very strange. No, I don't think they've got the balls (and the technical reason) to postpone 10nm for one more year.
