I did some actual measurements just to confirm it, here is minecraft in default configuration running @ 100fps and the cpu+gpu consumption is around 6w in total. If you add about 5w for display backlight and other components the total would be 9-10 hours of play time on my 100wh battery.
Can you please take the same measurements on your system? I'd like to see how good is the alternative.

Can you please take the same measurements on your system? Maybe ryzen system is better than intel, never had one.
