Few years ago I actually had bought Gigabyte BRIX with i3-7100U, when my main motivation was to have something at home to play with AVX2.
Fortunately, apart from that objective, which did not last more than few weeks anyway, this miniPC found very intensive use by other family members.

Also, I would think that at majority of real-world workloads, Skylake-X/Cascade Lake is few percents slower clock-for-clock than "normal" Sky/Kaby/Coffee/etc lakes. At least, that's an impression that I got from looking at SPECInt scores.
