efficiency will significantly depend on TDP, as the two Meteor Lake chips are only more efficient than the Ryzen 7 7840HS with a power consumption of 30 watts or more. At 15 watts, the Ryzen 7 7840HX was about 30% more efficient than the Core Ultra 7 155H, and that probably means Meteor Lake won’t be the processor of choice for handheld gaming PCs like the Steam Deck and ROG Ally.
