Instead, you’ll just have the 256GB model, now at $400. Valve is phasing out the 64GB and 512GB models of the Steam Deck now that the Steam Deck OLED is arriving. A point in the Steam Deck’s favor, however, is that Valve is now offering refurbished Steam Decks that cut the price as low as $320. To get 512GB, which is what the ROG Ally with the Z1 Extreme has, you’ll need to spend $650. The Steam Deck is as cheap as $400, but that’s only with 64GB of slow storage. A cheaper model sporting the Ryzen Z1 is available now, too, priced at $600. It’s currently available from Best Buy exclusively, and although I was worried it would sell out immediately, it’s still in stock for list price. The ROG Ally with the Z1 Extreme costs $700.
