Years - I don't think many people around here quite comprehend TDP limits of handheld devices, in addition to AMD's designs being quite inferior to nVidia's in that regard.

What is TDP?

Thermal Design Point

basically, what he say is that yeah, you could build a ps4 level switch right now, if you look only at what gpu and board that are available. However the trouble with such a device is the limited space you have to get rid of the heat generated. the more power you have, the more heat is produced. So you have to limit your power to allow the device to evacuate heat

So a portable PS4 would have a very hard time to get all that heat out of the device
