Lenovo has launched its flagship Legion Go S model, featuring SteamOS pre-installed alongside AMD's powerful Ryzen Z1 Extreme processor. This premium handheld packs substantial hardware with 32GB RAM and a spacious 1TB SSD. While priced at $829.99 (exclusively at Best Buy), its performance justifies the cost as our new top pick for best handheld gaming PC.

Unless you require Windows 11 compatibility or the Steam Deck's signature trackpads, this represents the current pinnacle of handheld gaming PCs. Our review scored it 9/10:

"By adopting SteamOS and upgrading to the Z1 Extreme chip, Lenovo's Legion Go S establishes itself among the elite handhelds available, highlighting Microsoft's remaining work for optimal handheld Windows performance."

With multiple Legion Go S variants on the market, selecting the right model proves crucial. Earlier 2024 releases included Windows 11 versions with weaker Z2 Go chips, followed by SteamOS models still using that processor. This newest SteamOS/Z1 Extreme combination outperforms the Steam Deck hardware, capable of running demanding newer titles like Doom: The Dark Ages that challenge Valve's device.

Those hesitant to purchase shouldn't worry - we're experiencing a golden age for handheld gaming PCs. Microsoft and ASUS plan Xbox ROG Ally and Z2 Extreme-powered Xbox ROG Ally X releases later this year featuring optimized Windows 11 versions.

Additional Z2 Extreme-powered devices will emerge soon, but for gamers seeking immediately available SteamOS efficiency, this Legion Go S with Z1 Extreme represents the ideal choice. Truly an exciting time for portable PC gaming.
