Well, Moore's law is dead turned out to be correct, he said months ago that the IPC uplift would be 11-12%, something I completely agreed with based on the fact that Intel was making the ambiguous claim of "double digit IPC gains". If Intel achieved anywhere near 19% as AMD did, they would have been touting that specific figure all over the place, but the fact that they just said "double digit" definitely meant it was the on the low end of what constitutes "double digit".
I bet AMD will release an XT/Zen3+ refresh soon after on an improved 7nm node with 5% performance gains, since Zen3 has been released on the same exact 7nm node as Zen2, which seemed weird to me at first, but makes sense. Make more money now by using the same 7nm process with no increased costs, and have the 7nm+ in your back pocket later on to combat Intel AND justify keeping MSRPs exactly where they are despite increased competition.
