The "Frost" namesake for the 2019 NUC9i7xxx seems intentional, and an awesome return to those lower TPCs. The Radeon partnership on the NUC platform appears to be over starting in 2019. The 2020 NUC9i9's are rated at 45w, if the charts are to believed. I like the bump to max memory of 64GB.
All Speculation Until The Specifications Are Published
