My next ROCK will probably not be an 8th gen NUC.
asrock Deskmini 110 with i3-7350K (2x4.2GHz), runs ROCK
NUC8 i3-8109U: Geekbench Single Core: 4805
NUC8 i7-8559U: Geekbench Single Core: 5072
i3-7350K: Geekbench Single Core: 5662
The i3-7350K is the last i3 with two cores. i3-8350K already has four cores, lower frequency and a lower Geekbench Single Core score of 5469. Newer is not always better.
In order to beat the i3-7350K for single core performance one needs to go into 8th gen i5 or i7 territory, which will have 90Watt TPD and not fit into asrock Deskmini 110 any more.
