The handheld PC market is currently divided between powerful Windows devices, like the ASUS ROG Ally X, and Steam OS-powered devices that focus on gaming immersion. Steam OS allows users to access their game libraries immediately upon booting, providing a distraction-free experience. In performance comparisons, devices like the Lenovo Legion Go S show a 69% speed increase on SteamOS (39 fps) compared to Windows (23 fps), while the ROG Ally X can see a 32% performance boost with SteamOS.
Battery life differs significantly, with the Steam Deck offering 3 to 6 hours of gameplay versus the ROG Ally X's 2 to 4 hours, despite the latter having a larger battery. Windows handhelds provide compatibility with various gaming platforms but suffer from inefficiencies due to background processes that consume CPU resources. Microsoft's Xbox Full Screen Experience attempts to improve usability but does not resolve the underlying issues.
Windows handhelds typically have 8GB or 16GB of VRAM, which may be insufficient for future games, while SteamOS's lighter footprint allows for better VRAM allocation, enhancing performance. SteamOS is gaining traction not necessarily due to technical superiority but because of its efficiency in addressing the unique constraints of handheld gaming.
