Zen+ has about the same IPC as the Intel processors from when it was released, the problem was just lower clockspeeds. The single threaded gap was somewhere around 5%, not the 40%+ of Bulldozer.
Zen 2 raises IPC by 15%, and raises clock speeds by a solid 10% or more. Single threaded Zen 2 performance is not even a slight concern for me.
Add 9% to the benchmark result this entire thread is about, because this engineering sample was not running at the specified boost frequency that the 3950X will have. Intel has nothing to compete against that... it should be uncontested.
On Epyc, their clock speeds were generally comparable to Intel's, and the single threaded performance was already great there, except for a few specialty processors that Intel released for servers that don't care about high core counts. Epyc 2 stands to completely annihilate any advantage Intel had left.
AMD Zen has always used less power than Intel for each unit of work done, which was one of the original surprises, so... power consumption is absolutely not favoring Intel.
I really feel like you're mentally comparing to the old Bulldozer Opteron processors, based on the concerns you listed.
