I hope people realize these are 1st-generation Zen CPUs that are Not Very Fast(tm), not the respectable Zen2 parts you've been reading good things about. AMD's marketing is very confusing right now. There are not any Zen2 APUs.
Would have to look closer at the other attributes of each NUC to make a really good determination, but the Intel chips look to be higher performers, if not by a wide margin.
EDIT:
My bad - didn't read the above article closely enough. The Sequoia v8 comes with a Ryzen V1807B (not a V1605B) as found in my comparisons above. See the reply below for better links.
Zen 1s are plenty fast. They're just not as fast as Zen 2s. The first generation 32 core Threadripper was the fastest CPU in the world when it was released, and that wasn't that long ago.
They are not very competitive for the price. They are about 50% slower than same-priced quad core Core i3 CPUs on Chrome Octane 2 benchmarks, 25% slower on video encoding, etc. AMD is free-riding the good reviews of their latest parts by giving these APUs very similar model numbers. In reality these are obsolete parts.
