At CES 2025, we learned that the upcoming Lenovo Legion Go S PC handheld will be the first officially licensed SteamOS-powered device not manufactured by Valve. There has been much speculation about whether and when SteamOS would officially move beyond the Steam Deck, and it’s finally happening.
Valve itself commented on the subject in a blog post, explaining that this will be the exact same version of SteamOS available on their own Steam Deck. A team is working to ensure everything will work just as well when the device ships. Moreover, Valve said that this work to support the Lenovo Legion Go S will also improve compatibility with other handhelds. Before this handheld ships on the market, Valve plans to ship a beta version of SteamOS that will improve the experience on other handhelds for users to download and test for themselves. The work will continue after the device’s launch, too, as you would expect from Valve.
Interestingly, it seems like the Lenovo Legion Go S will have two variants, one without SteamOS and one with Valve’s operating system. The former will be available later this month with the regular Windows, priced at $729.99 initially, although a configuration priced at $599.99 is expected to be available in May. That’s also when the SteamOS version of the handheld is due to launch at an even cheaper of $499.99.
The $729.99 version is the one equipped with the Lenovo-exclusive AMD Ryzen Z2 Go processor, which likely explains the higher price. The other two versions, either Windows or SteamOS, will feature the AMD Ryzen Z1 Extreme processor. The price difference is likely due to licensing fees.
Other than that, the specifications should be the same: 8” WUXGA 16:10 120Hz PureSight touch display with Variable Refresh Rate (VRR) support, up to 32GB of 7500Mhz LPDDR5X RAM, 3-cell 55.5Whr battery, two USB 4 ports, a microSD card reader, and WiFi6e support.
