I mean we have already seen people overclock the steam deck to a ridiculous like 25 watts already and it not completely blow up. With a higher efficiency and also ram speed improvement that were one of the biggest bottlenecks back then even with overclocking it seems like we can see some nice tangible safe boosts
Yea but the framerate still manages to be marginally higher. Which means with the same wattage it must be a good amount better like you said
