ASUS ROG Ally X vs Valve Steam Deck OLED
The ROG Ally X and Steam Deck OLED represent the two philosophies of handheld gaming: raw Windows horsepower versus SteamOS polish. The Ally X's Ryzen Z1 Extreme and 80 Wh battery give it more sustained performance and USB4/eGPU support, while the Steam Deck OLED counters with a gorgeous 90 Hz HDR OLED screen, less weight and Valve's best-in-class suspend/resume. Most buyers who don't need Windows-only software are better served by the Steam Deck OLED's smoother experience; power users lean Ally X.
