I mistakingly wrote 6600, it’s similar to a lower clocked RX 7600. Though it’s performance is not that much different than the 6600. It’s a okay GPU. It’s a entry level GPU, i.e. the most inexpensive to get while still getting good value.

Depends on what you expext I guess? The RX 6600 is still capable of playing any game, but it’s clearly an entry level card.

My guess is that Valve is aiming for a price similar to the current steam deck, and also tried to keep the power usage low (30W CPU + 110W GPU).
