Outside of the better gpu, the one advantage the other devices have is emulation. Steamdeck sits on the edge of performance for some of the harder to emulate devices heavy titles (PS3, Switch). The ones using Ryzen 3/4 would trivially handle emulation better than the Steamdecks CPU, which uses Ryzen 1+ (part of the reason why its low cost)
