Valve opened the handheld PC gaming category — now it has real competition and a real market

When Valve released the Steam Deck in February 2022, the reception was skeptical in some quarters: too heavy, too hot, too niche, Linux-based software compatibility would be a deal-breaker. Four years later, the Steam Deck is on its second generation, has sold an estimated three to five million units, and spawned an entire product category that ASUS, Lenovo, MSI, and others are actively competing in. The handheld gaming PC is not a niche anymore — it's a real market segment with real hardware tradeoffs and a specific audience that finds it genuinely useful.

The Steam Deck 2 and what it fixed

The original Steam Deck's main weaknesses were battery life (2-4 hours for demanding games), display (a 720p LCD in an era of 1080p OLED expectations), and weight (669g, noticeably heavier than a Nintendo Switch). The Steam Deck OLED, released in November 2023 and continuing as the base model through 2026, addressed two of these: a larger, brighter OLED display and a larger battery that extended runtime by 30-50% depending on workload. It also dropped about 30g.

The AMD APU inside remains the same Zen 2 + RDNA 2 chip from the original, which is now two hardware generations behind AMD's current lineup. Valve has been deliberate about not creating hardware fragmentation: every Steam Deck runs the same chip, which means developers can target a fixed hardware profile rather than a range. This benefits the software ecosystem at the cost of raw performance improvement.

SteamOS 3, Valve's Linux-based operating system built on top of Arch Linux, has matured significantly. Proton — the compatibility layer that runs Windows games on Linux — now runs approximately 80% of the Steam library with some level of playability, and a large majority of new releases work on day one. The "Deck Verified" system gives users a clear signal before purchase. For the Steam Deck specifically, the software experience is far smoother than running Windows, because Valve has full control over the hardware-software interface.

The Windows-based competitors

ASUS launched the ROG Ally in May 2023 and the ROG Ally X — a higher-spec, larger-battery revision — in June 2024. Both run Windows 11. The ROG Ally X uses AMD's Z1 Extreme chip, the same Zen 4 + RDNA 3 APU as the Steam Deck's competitors, and delivers meaningfully better performance than the Steam Deck on demanding titles: roughly 30-50% more GPU performance. At 800p or 1080p in modern AAA games, the ROG Ally X is the faster device.

Lenovo's Legion Go takes a different approach: a larger 8.8-inch 1600p screen, detachable controllers (similar to the Nintendo Switch's Joy-Cons concept), a kickstand for tabletop play, and a dedicated "FPS mode" that turns the right controller into a mouse. At $699-799, it targets the enthusiast end of the market. MSI's Claw, which shipped in 2024 with an Intel Meteor Lake chip, got off to a rough start with high power consumption and lower performance relative to the AMD competition; subsequent driver and firmware updates improved the situation but didn't close the gap.

The Windows-on-handheld experience has an inherent tension: Windows was designed for desktops with keyboards and mice, and running it with a gamepad and touch interface exposes every place it was not designed for handheld use. Wake from sleep is unreliable. Power management is poorly tuned for battery preservation at low TDP settings. The start menu requires either a touchscreen tap or awkward cursor navigation with a thumbstick. ASUS ships its Armoury Crate overlay to manage TDP, fan curves, and game mode, which helps — but adds another layer of software that can fail.

What you can actually play, and how well

The honest answer to "can you play modern AAA games on a handheld PC?" is yes, with caveats. At the device's native display resolution — 800p on the Steam Deck, 720p or 800p typically targeted on the ROG Ally despite its 1080p screen — with medium graphics settings and FSR (AMD's upscaling technology), most games from the last three or four years run at 30-60 fps. Cyberpunk 2077, Baldur's Gate 3, Elden Ring, Red Dead Redemption 2 — all playable. Not at the visual fidelity you'd get from a gaming desktop, but playable in a way that's genuinely enjoyable.

Older games, indie titles, and anything below the graphically intensive AAA tier run very well. The Steam library contains thousands of games that target 60fps on modest hardware. For players with large existing Steam libraries, the ability to play those games away from a desk — on a plane, on a couch, in bed — is the core value proposition, and it works.

Battery life varies enormously by workload. Less demanding games (Hades, Stardew Valley, older games) can run for five to eight hours. The most demanding modern titles drain the battery in 90 minutes. Most users land around three to four hours for typical gaming sessions, which is fine for a commute or a short trip, limiting for a transatlantic flight.

Who this is actually for

The handheld PC market's core demographic is PC gamers — people with existing Steam libraries who want to play those games in contexts that previously required being at a desk. This distinguishes it from the Nintendo Switch's market, which includes many people who don't own a gaming PC and for whom portability is the primary consideration. A Switch owner and a Steam Deck owner can overlap, but the value proposition is different.

The devices also function as desktop PCs via docking stations — plug into an HDMI-capable dock, connect a keyboard and mouse, and you have a capable (if not powerful) desktop workstation. Some buyers use this as their only computing device. The SteamOS Steam Deck is awkward as a general-purpose computer; the Windows-based ROG Ally is better suited to this use case.

Hardware revisions are coming. AMD's next-generation APU families — Strix Halo and its successors — bring significantly more GPU performance at the same or lower power envelopes. When those chips arrive in handhelds in 2026-2027, the performance ceiling for the category will rise substantially. Whether Valve or ASUS gets there first with a compelling device at a reasonable price point is the question the market is watching. The Steam Deck's software ecosystem — built over four years of Proton compatibility work — remains its most durable competitive advantage over Windows-based alternatives.
