Handheld Gaming PCs Explained: Steam Deck vs ROG Xbox Ally vs Legion Go vs Switch 2
Handheld PCs and the Switch 2 look similar but work very differently. Here's how their operating systems, game libraries and battery life compare.
Pick a handheld by the games you want to play and the operating system that runs them. The Steam Deck runs Valve’s SteamOS and is the simplest way to play a Steam library on the go. Windows handhelds like the ROG Xbox Ally and Lenovo Legion Go run almost any PC game store, including Xbox Game Pass, but take more tinkering. The Nintendo Switch 2 isn’t a PC at all: it plays Nintendo’s own library, which you can’t get anywhere else.
Two kinds of handheld
Handheld gaming PCs are compact computers with built-in controls. They play the PC games you buy from stores like Steam, Epic Games Store, GOG or the Xbox app, and many can plug into a monitor and act like a small desktop.
Dedicated consoles such as the Switch 2 run only games released for that system, bought from the console maker’s store or on physical game cards. They’re simpler but closed.

Operating system: the biggest difference
SteamOS
SteamOS boots straight into a console-like Steam interface. Games from your Steam library install and launch with a tap, and suspend/resume works much like a console. Valve’s Steam Deck Verified ratings tell you whether a game is Verified, Playable, Unsupported or Unknown on the device.
Many Windows games run through a compatibility layer called Proton. The main exception is multiplayer games whose anti-cheat systems block Linux, which means some popular online shooters and competitive games won’t run. Check a game’s status before you buy the hardware for it.
Windows 11
Windows handhelds run nearly every PC game and launcher, including Xbox Game Pass for PC and games with strict anti-cheat. The trade-off is that Windows was designed for keyboard and mouse, so you’ll occasionally deal with pop-ups, updates and small text. Manufacturers add their own overlays, and the ROG Xbox Ally models launch into a full-screen Xbox interface to make this more console-like.
Nintendo’s system
The Switch 2 runs only Switch 2 games and most original Switch games. It’s the most plug-and-play option, with features like docking to a TV built in, but there’s no way to install PC game stores on it.
Battery life: why capacity isn’t everything
Battery capacity in watt-hours (Wh) is only part of the story. Real play time depends on:
- The game. Demanding 3D games can drain any of these devices in around two hours; lighter indie games can last several times longer.
- Power mode. Most handhelds let you cap the processor’s wattage. Lower settings stretch battery life at the cost of frame rate.
- Screen brightness and refresh rate. Dropping from 120 Hz to 60 Hz and lowering brightness help noticeably.
- Operating system efficiency. SteamOS is generally lighter than Windows in the background, which is one reason Lenovo and others now sell SteamOS versions.
For long trips, a USB-C power bank that supports USB Power Delivery at a high enough wattage keeps you going. See our guides to choosing a power bank and USB-C cables, since a weak cable can limit charging speed.
Performance and screens
All the Windows and SteamOS handhelds use AMD chips with integrated graphics, the newer of which are noticeably faster than the Steam Deck’s older custom chip. More power usually means more heat and shorter battery life at full speed.
Screen size affects comfort and weight. Larger 8- to 9-inch screens look great but make the device heavier for long sessions. OLED screens offer deeper blacks and vivid color; high-refresh LCDs feel smoother in fast games.
Storage and upgrades
- Most handheld PCs use an M.2 2230 SSD that can be replaced, though opening the device may affect your warranty. Check the manufacturer’s guidance first.
- All have a microSD slot for extra games. Switch 2 requires microSD Express cards for game storage, not ordinary microSD cards.
- Modern PC games are large, so 512 GB or more is a comfortable starting point.
Controllers and extras
The Legion Go line offers detachable controllers and a kickstand. The Steam Deck has trackpads that help in mouse-driven games. You can also pair external controllers with any of them over Bluetooth; if you’re using a PlayStation controller on a Windows handheld, our guide to using PS4 and PS5 controllers on Windows covers the setup.
Playing legally
All of these devices work with games you buy or subscribe to through official stores. We don’t cover downloading game files from unofficial sources. Besides being illegal for copyrighted games, files from such sites are a common way malware spreads. Many classic games are available legally through official re-releases, subscription services and the stores above.
Who should get which
- Already have a big Steam library: Steam Deck, or a SteamOS edition of another handheld.
- Use Xbox Game Pass or play online games with strict anti-cheat: a Windows handheld such as the ROG Xbox Ally.
- Want the biggest screen and detachable controls: Legion Go 2.
- Want Mario, Zelda and Pokémon, and the least fuss: Switch 2.
Bottom line
Choose by game library first. SteamOS offers the smoothest console-like PC experience for Steam games, Windows handhelds give maximum compatibility in exchange for some friction, and the Switch 2 is the only way to play Nintendo’s games. Check battery expectations against the games you play, and budget for storage and a good USB-C charger.
FAQ
Can the Steam Deck play Game Pass games?
Not natively. Game Pass for PC needs Windows. Cloud streaming through a web browser is possible, but it depends on a strong internet connection.
Can I install Windows on a Steam Deck?
Valve provides Windows drivers, so yes, but you lose SteamOS’s console-like experience unless you set up dual boot. Most owners keep SteamOS.
Do handheld PCs work with a TV?
Yes. Connect through USB-C to a dock or a USB-C-to-HDMI adapter, then use a controller from the couch.
Does the Switch 2 play original Switch games?
Most of them, according to Nintendo, though a small number may have issues. Nintendo publishes a compatibility list on its support site.
