That would explain it. I've been pushing my little Asus vivobook so hard trying to catch your scores. Pushed the tDP to 54watts to try catch you and I'm still struggling. I might just have to breake out the Conductonaut and replace my thermal compound.

My TDP is set to 63W, it pulls 58W max but I have heatsinks on the inductors, otherwise it power throttles all the way down to 300mhz when you push it
