Have been using a 7735HS (6800H) based mini PC for the last few days, very impressed with it -- the entire machine idles at 10W, light load < 20W, medium load at < 40W and heavy load ~ 60W. The fan isn't on most of the time. The latest generation is likely better, and U series is even quieter. It has better performance and produces less heat than my Intel NUC and laptop.
