The handheld gaming PC market is heating up with Lenovo's latest entry—the Legion Go S running Steam OS. This new contender aims to challenge Valve's Steam Deck dominance by combining powerful hardware with the flexibility of Steam OS, creating a compelling alternative for portable gaming enthusiasts.

A New Challenger Emerges

Lenovo's Legion Go S enters the arena with specifications that rival—and in some cases surpass—the Steam Deck. Powered by an AMD Ryzen Z1 Extreme processor and featuring a 7-inch 120Hz VRR display, the device promises smoother gameplay and better performance in demanding titles. The inclusion of Steam OS ensures compatibility with thousands of games from the Steam library, making it a direct competitor to Valve's offering.

Hardware Showdown: Legion Go S vs. Steam Deck

  • Processor: The Legion Go S uses AMD's Ryzen Z1 Extreme, which outperforms the Steam Deck's custom AMD APU in multi-threaded workloads.
  • Display: A 7-inch 120Hz VRR screen gives the Legion Go S an edge over the Steam Deck's 60Hz panel, especially for fast-paced games.
  • Storage: Both devices offer SSD options, but the Legion Go S supports faster NVMe storage configurations.
  • Controls: Lenovo's detachable controllers with Hall Effect joysticks aim to reduce drift issues, a common complaint with the Steam Deck.

Steam OS: The Great Equalizer

By adopting Steam OS, Lenovo ensures broad game compatibility while benefiting from Valve's ongoing optimizations. The Linux-based OS provides a console-like experience with seamless updates and Proton support for Windows games. However, some users may miss Windows-specific features like Xbox Game Pass integration.

Battery Life and Portability

Early tests suggest the Legion Go S offers comparable battery life to the Steam Deck—around 4-6 hours depending on game intensity. The device's slightly larger form factor may impact portability, but the improved cooling system helps maintain performance during extended sessions.

Game Compatibility and Performance

Thanks to Steam OS, most verified Steam Deck titles run well on the Legion Go S. Performance benchmarks show:

Game Title Steam Deck (FPS) Legion Go S (FPS)
Elden Ring 40-50 45-55
Cyberpunk 2077 30-40 35-45
Hades 60 120 (with VRR)

The Legion Go S's higher refresh rate display particularly benefits fast-paced games, while its additional GPU power helps in graphically intensive titles.

Potential Drawbacks

  • Price: The Legion Go S starts at $699, making it more expensive than the base Steam Deck model.
  • Software Limitations: While Steam OS is excellent for Steam games, some launchers and services remain problematic.
  • Weight: At 640g, it's slightly heavier than the Steam Deck (669g), which might affect long gaming sessions.

The Verdict: Who Should Buy It?

The Legion Go S presents a compelling option for gamers who want:
- Higher performance than the Steam Deck
- A superior display with VRR support
- Detachable controllers with improved ergonomics

However, the Steam Deck remains the better choice for:
- Budget-conscious buyers
- Those deeply invested in the Steam ecosystem
- Gamers who prioritize absolute portability

As the handheld PC market continues to evolve, competition like this ultimately benefits consumers, pushing innovation and driving prices down. The Legion Go S doesn't just compete with the Steam Deck—it elevates the entire category.
