Released in February 2025, the Lenovo Legion Go S ($499–$729) runs on an AMD Ryzen Z2 Go and ships with either SteamOS or Windows 11, giving buyers an OS choice from the outset. The Steam Deck OLED ($549–$649), released November 2023, uses AMD's Sephiroth chip and runs SteamOS by default with Windows 11 as an option. Both are high-end horizontal handhelds capable of emulating up to Wii U. The Legion Go S suits buyers who want Windows flexibility at a potentially lower entry price; the Steam Deck OLED appeals to those who value a more mature, community-tested platform.
