Is it worth upgrading from (ROCK) NUC5i5 to NUC8i3(or 5)?

The core CPU architecture, # of processing pipes and chip die lithography @ 14nm is no different between the 5th, 6th, 7th and 8th Gen Processors.
The additional clock speeds, as Intel was able to push the 14nm based architecture, is not able to be used as the NUC used the mobile version and limit them for the 15W TDP footprint needed for the limited cooling a NUC chassis can provide.

I don’t think many people realize just how little the steps are between some NUC generations. Sometimes, it is not even a move forward but more a re-arrangement of capability focus, like focus on cooling/power saving vs. any type of actual usable speed increase.
