Seems like Deck beats out Ally up to 10w. 11w they even out. After Ally surpasses Deck. Also note Allt can go up to 30w which this graph doesn’t show. Allow fan noise and heat is also considerable lower up to 20w where as Deck heat and fan noise gets way louder closer to 15w.
I usually limit my deck to 9-10w. After that it hits heavy diminishing returns, and this graph just confirms my feelings.
The graph also shows Ally can get some real performance upto 18w when it starts getting diminishing returns
