Very interesting. I was a bit out of the loop on Intel mobile CPUs; I looked up the benchmark specs for it when purchasing and saw that it generally trounces the 255U.

I've been really quite happy with it - most of the time the CPU runs at about 30 deg C, so the fan is entirely off. General workloads (KDE, Vivaldi, Thunderbird, Konsole) puts it at about 5.5 watts of power draw.
