I will critique a couple of issues that I had with the video. His build had a 1600 AF, and 3600 RAM, and he made the claim that the 1600 AF was around 15% faster than the 1600 AE. I don't believe that to be true, at least, not under all-core load. The 12nm Zen+ was nearly identical in IPC and architecture to the 14nm Zen1 CPUs, there were no real IPC improvements, it was pretty-much a straight shrink. The improvements, were to top-end freq. (if doing an all-core manual OC), and single-threaded turbo (12nm was able to turbo higher, in same TDP envelope.) But the all-core stock turbo clock, is 3.4Ghz for both.
Also, with both Zen and Zen+, you would be hard-pressed to get 3600 RAM to run at XMP sufficiently stable. Zen2 is no problem with 3600 RAM, but it's a bit of a stretch to get Zen1/Zen+ to those DRAM clocks. Granted, Zen+ is a bit better. 3000 RAM or 3200 RAM was really pushing it with Zen1, with Zen+, it's a bit easier, but ... unless you're planning on future-proofing to drop in a Zen2 (7nm) CPU, the 3600 RAM on his build was IMHO overkill.
Edit: Don't get me wrong, I love his build vids, but he's not infallible, either.
Edit: My points are minor, and don't invalidate the premise behind his video.
