Lenovo’s Legion Go S will be the first authorized third-party PC gaming handheld to ship with Valve’s SteamOS.

Lenovo revealed the Legion Go S at CES 2025, confirming the SteamOS support alongside a variety of specs and features, including:

• 8-inch screen with 120Hz and variable refresh rate (VRR) support.
• Hall effect analogue sticks (uses magnetic fields and electric sensors to reduce stick-drift and provide more accurate in-game controls).
• Adjustable trigger switches.
• 55Wh battery.
• Dual USB4 ports.
• MicroSD card slot.
• Headphone jack.

Some of the other specs, including storage capacity and chips, depend on the model. (More on those differences below.)

On top of all that, the Legion Go S has eschewed the Nintendo Switch-like detachable gamepads featured on the original Legion Go in favour of a traditional single-piece hardware build à la Steam Deck for even more similarities to Valve’s own handheld.

Interestingly, though, there will also be a Windows 11 version of the Legion Go S that launches this month, well before the May release of the SteamOS model. (Valve told The Verge this is because it’s still working with Lenovo on finalizing the SteamOS integration.) The Windows 11 Legion Go S will cost $729.99 (about $1047 CAD) and feature AMD Ryzen Z2 Go, 32 GB of RAM and a 1 TB SSD. Additionally, a $599 USD (about $860 CAD) model will ship in May and sport AMD’s Z2 Go, 16 GB of RAM, and 1 TB of storage.

If you’re willing to wait until May anyway, you’ll also have two options of the SteamOS Legion Go S. The first is priced at $499 USD (about $715 CAD) and features AMD’s Ryzen Z1 Extreme CPU, 16GB of RAM, and 512GB of storage, while the second will cost $599 USD (about $860 CAD) and boast the new AMD Ryzen Z2 Go processor (exclusive to Lenovo), 16 GB of RAM and a 1 TB SSD.

It’s worth noting that Lenovo also showed off a prototype at CES for the Legion Go 2, which features Switch-like detachable controllers and an 8.8-inch OLED screen, although it’s unclear when that might end up getting a commercial release.
