Buying advice

Steam Deck OLED

The Steam Deck OLED is the gold standard for handhelds, featuring a stunning 7.4-inch display with a smooth 90Hz refresh rate. It delivers a solid 800p gaming experience, running modern titles reliably at 40-60 frames per second. It is the best choice for players who want a seamless, console-like experience for their entire Steam library on the go.

ROG Xbox Ally X

ROG Xbox Ally X is the higher-end new Xbox-branded Ally handheld rather than the older Z1 Extreme model. Its official spec sheet highlights Ryzen AI Z2 Extreme, 24GB LPDDR5X memory, 1TB storage, and an 80Wh battery, making it the stronger Windows handheld choice when PC game compatibility and longer unplugged sessions matter most.
