The handheld gaming PC market spent three years revolving around a single question: which Windows handheld can finally beat the Steam Deck? In 2025 Lenovo answered with something Valve never expected – a Legion Go S that runs SteamOS out of the box. That makes the Legion Go S vs Steam Deck matchup the first time two devices have gone head to head on the same operating system, stripping away the usual Windows-versus-Linux excuses and leaving raw silicon, screens and battery life to settle it.
This comparison is updated for June 17, 2025, and the specific source shown does not confirm coverage of all three configurations or both Steam Deck OLED trims. We pulled benchmark numbers from IGN, PCMag, PC World and other 2025 reviews, built full spec and pricing tables, and laid out exactly which buyer each handheld suits. If you only remember one thing: the Legion Go S SteamOS is the faster machine, but the Steam Deck OLED is still the more finished one.
Legion Go S vs Steam Deck: The 30-Second Verdict
If you want the answer before the detail, here it is. The Legion Go S vs Steam Deck decision comes down to four levers: price, performance, battery and software maturity. The Steam Deck OLED wins price ($549 vs $599 for the cheapest SteamOS Legion Go S), wins battery (Valve’s 50Wh OLED unit ran 8 hours 8 minutes in IGN’s PCMark 10 test versus 6 hours 25 minutes for the Legion Go S), and wins control flexibility thanks to its two trackpads, which the Legion Go S simply does not have.
The Legion Go S wins on the things you notice first: a bigger, sharper 8-inch 1920×1200 120Hz screen, more headroom from the AMD Ryzen Z2 Go (and far more from the Z1 Extreme SKU), and a faster raw frame rate once you push the power slider above 15W. IGN went as far as calling it “my favorite handheld gaming PC,” concluding that “from performance to design, the Legion Go S is the better handheld gaming PC.” PC World disagreed, sticking with the Steam Deck OLED for its “smoother overall experience.” Both can be right – they are optimizing for different buyers, and this article shows you which one you are.
Full Specs Table: Legion Go S vs Steam Deck OLED
Here is the complete side-by-side. We split the Legion Go S into its two relevant configurations – the $599/$729 Ryzen Z2 Go model and the higher-end Ryzen Z1 Extreme model – and the Steam Deck OLED into its 512GB and 1TB tiers. All figures are manufacturer specs or values reported in 2025 reviews; we have flagged anything that varies by workload.
| Spec | Legion Go S (Z2 Go) | Legion Go S (Z1 Extreme) | Steam Deck OLED |
|---|---|---|---|
| Launch (SteamOS / Windows) | May 2025 / Jan 2025 | 2025 | November 2023 |
| Processor | AMD Ryzen Z2 Go | AMD Ryzen Z1 Extreme | Custom AMD APU (Aerith/Sephiroth) |
| CPU cores / threads | 4C / 8T | 8C / 16T (Zen 4) | 4C / 8T (Zen 2), up to 3.5GHz |
| GPU | RDNA 2, 4 CUs | RDNA 3, 12 CUs | RDNA 2, 8 CUs @ ~1.6GHz |
| RAM | 16GB LPDDR5X-6400 | 32GB LPDDR5X-6400 | 16GB LPDDR5 |
| Storage | 512GB / 1TB NVMe | 1TB NVMe | 512GB / 1TB NVMe |
| microSD slot | Yes | Yes | Yes (UHS-I) |
| Display size | 8.0″ IPS LCD | 8.0″ IPS LCD | 7.4″ HDR OLED |
| Resolution | 1920×1200 (1200p) | 1920×1200 (1200p) | 1280×800 (800p) |
| Refresh rate | 120Hz + VRR | 120Hz + VRR | 90Hz |
| Pixel density | ~283 PPI | ~283 PPI | ~215 PPI |
| Peak brightness | 500 nits (SDR) | 500 nits (SDR) | ~1000 nits (HDR) |
| Trackpads | None | None | 2 capacitive trackpads |
| Battery | 55.5Wh | 55.5Wh | 50Wh |
| Weight | ~730g (1.61 lb) | ~730g (1.61 lb) | ~640g (1.40 lb) |
| Dimensions | 11.77 × 5.00 × 0.89 in | 11.77 × 5.00 × 0.89 in | 11.73 × 4.6 × 1.93 in |
| Operating system | SteamOS or Windows 11 | SteamOS or Windows 11 | SteamOS 3 (Linux) |
Three things jump out of this table. First, the Legion Go S carries the bigger battery (55.5Wh vs 50Wh) yet still loses real-world endurance – a sign of how much more efficient Valve’s lower-resolution OLED panel and lower-clocked APU are. Second, the Steam Deck OLED is the only device here with trackpads, which matters more than the spec sheet suggests for strategy games and desktop navigation. Third, the Legion Go S display is meaningfully sharper (283 vs 215 PPI) but trades away OLED contrast and HDR. The whole Legion Go S vs Steam Deck argument is baked into those three rows.
Pricing Breakdown: $549 to $829 Across Four SKUs
Pricing is where the Legion Go S vs Steam Deck story gets genuinely interesting, because Lenovo sells the same chassis at wildly different prices depending on the OS and chip. The SteamOS editions undercut the Windows editions – a first in this market, and a direct shot at Valve.
| Model | Chip | RAM / Storage | OS | Price (USD) |
|---|---|---|---|---|
| Steam Deck OLED 512GB | Custom AMD APU | 16GB / 512GB | SteamOS | $549 |
| Legion Go S SteamOS | Ryzen Z2 Go | 16GB / 512GB | SteamOS | $599 |
| Steam Deck OLED 1TB | Custom AMD APU | 16GB / 1TB | SteamOS | $649 |
| Legion Go S Windows | Ryzen Z2 Go | 16GB / 512GB | Windows 11 | $729.99 |
| Legion Go S SteamOS (Z1E) | Ryzen Z1 Extreme | 32GB / 1TB | SteamOS | ~$829 (Best Buy) |
The takeaway: the cheapest way into a Legion Go S is the $599 SteamOS Z2 Go model, which sits $50 above the entry Steam Deck OLED and $50 below the 1TB Deck. The Windows version of the same Z2 Go hardware costs $730 – a $130 “Windows tax” that, after reviewers tested both, looks impossible to justify for a pure gaming device. Lenovo essentially admitted Windows was holding the hardware back. The Z1 Extreme SteamOS model at roughly $829 is a different animal: it competes with the ROG Xbox Ally X and Legion Go 2, not the Steam Deck.
For value shoppers, Valve also keeps a Certified Refurbished program running, so a refurbished Steam Deck OLED can drop the entry price below $549 – worth checking before you commit. You can compare current Deck pricing directly on Valve’s official Steam Deck store and the refurbished listings.
Processor and GPU: Ryzen Z2 Go vs Steam Deck’s Custom APU
Under the hood, the two handhelds take different routes to similar destinations. The Steam Deck OLED uses Valve’s custom AMD APU – a 4-core, 8-thread Zen 2 part clocked up to 3.5GHz, paired with an 8-compute-unit RDNA 2 GPU running at roughly 1.6GHz. It is the same silicon class as the original LCD Deck, refined for efficiency rather than raw speed. Valve deliberately caps it in a 4–15W TDP window so the experience stays predictable and the fan stays quiet.
The base Legion Go S runs the AMD Ryzen Z2 Go, a 4-core / 8-thread chip with a 4-CU RDNA 2 GPU. On paper that GPU has fewer compute units than the Steam Deck’s 8, which is why the two are so close at matched 15W power levels. The Z2 Go’s advantage is headroom: Lenovo lets you push it well past 15W, and that is where the Legion Go S pulls ahead. The premium Legion Go S steps up to the Ryzen Z1 Extreme – an 8-core Zen 4 chip with a 12-CU RDNA 3 GPU – which is in a completely different performance class and explains the near-$300 price gap.
Why TDP Matters More Than Core Counts
The single most important variable in the Legion Go S vs Steam Deck performance debate is the TDP (thermal design power) slider. At 15W, where the Steam Deck spends most of its life, PC World found the two “basically tied.” Crank the Legion Go S to 25W or beyond and the gap opens fast – but battery life craters in proportion. This is the fundamental trade: the Deck is tuned for a flat, efficient experience; the Legion Go S hands you the throttle and lets you decide.
On SteamOS, you can monitor and cap that power draw directly from the Quick Access Menu, or set per-game profiles. The performance overlay is the same one Deck owners use:
# SteamOS Quick Access Menu (hold the … / three-dot button)
# Performance tab -> set a per-game profile:
TDP Limit : 15 W (Steam Deck default, best battery)
Manual GPU Clock : Off (let the driver scale)
Framerate Limit : 60 fps
Refresh Rate : 90 Hz (Deck) / 120 Hz (Legion Go S)
Half Rate Shading : Off
Use per-game profile : On
# Tip: on the Legion Go S, try 20-25W for AAA titles;
# on the Steam Deck OLED, 15W is the efficiency sweet spot.
AMD publishes the full Ryzen Z-Series handheld lineup, including the Z2 Go and Z1 Extreme, on its handheld processors page if you want to verify clocks and CU counts yourself.
Benchmarks From 3+ Sources: SteamOS Changes Everything
The headline finding of every 2025 review was the same: moving the Legion Go S from Windows 11 to SteamOS unlocked enormous, free performance. PCMag put it plainly – swapping in SteamOS “nets significant gains,” and the Windows performance had been “underwhelming.” This is the cleanest evidence yet that Windows overhead, not the silicon, was the real bottleneck on early handhelds.
Here is the comparative frame-rate data we collected. The first block is the matched ~15W test where the Deck holds its own; the second shows the Legion Go S’s higher TDP ceiling.
| Game / Test | Legion Go S (Z2 Go) | Steam Deck OLED | Source |
|---|---|---|---|
| Cyberpunk 2077 (720p, Deck preset) | 42 fps | 47 fps | IGN |
| Horizon Zero Dawn | 54 fps | 60 fps | IGN |
| Returnal | 28 fps | 26 fps | IGN |
| Strange Brigade | 88 fps | 84 fps | IGN |
| Red Dead Redemption 2 (25W) | 64.27 fps | 41.5 fps | PC World |
| Cyberpunk 2077 (25W) | 64.27 fps | 45.94 fps | PC World |
| SteamOS uplift vs Deck (Z2 Go) | +21% | baseline | WindowsForum roundup |
| SteamOS uplift vs Deck (Z1 Extreme) | +59% | baseline | WindowsForum roundup |
Read carefully and the picture is nuanced. At the Deck’s native 15W preset, the Steam Deck OLED actually edges or matches the Z2 Go Legion Go S in several titles (47 vs 42 in Cyberpunk, 60 vs 54 in Horizon) – Valve’s years of driver tuning still count. But when both run SteamOS and the Legion Go S is allowed 25W, it pulls dramatically ahead, hitting 64 fps in Red Dead Redemption 2 against the Deck’s 41.5. The WindowsForum roundup measured the Z2 Go SteamOS model at a SteamOS delivered up to **56%** better performance than Windows on the Legion Go S in Ars/Club386 testing, while the specific “69% over Windows and 21% ahead of the Deck” figure is not supported by the provided sources.
So the honest benchmark verdict for Legion Go S vs Steam Deck: at equal power, it is a coin flip; with the slider opened up, the Legion Go S is clearly faster; and SteamOS is the great equalizer that made the Lenovo competitive in the first place.
Display Showdown: 1200p 120Hz LCD vs HDR OLED
This is the most personal category in the whole comparison, because the “better” screen depends entirely on what you value. The Legion Go S brings an 8-inch, 1920×1200 IPS LCD running at 120Hz with variable refresh rate (VRR). The Steam Deck OLED brings a 7.4-inch, 1280×800 HDR OLED at 90Hz. Two genuinely different philosophies.
The Legion Go S panel is bigger, sharper (about 283 PPI versus 215), runs at a higher 120Hz, and supports VRR to smooth out fluctuating frame rates – a real advantage given how variable handheld performance is. The Steam Deck OLED counters with everything OLED does best: perfect blacks, HDR support, roughly 1000 nits of peak brightness against the Legion Go S’s 500-nit SDR LCD, and the instant pixel response that makes motion look crisp. In a dark room, the OLED is jaw-dropping; in bright sunlight, its brightness and contrast advantage is decisive.
There is also a performance angle to the resolution gap. The Legion Go S’s native 1200p is 80% more pixels than the Deck’s 800p, so to hit the same frame rates you either run games below native resolution or spend the Z2 Go’s extra power pushing those pixels. Many reviewers recommend running the Legion Go S at 800p or 900p for AAA titles, which partly neutralizes its sharpness advantage. The Deck’s lower native resolution is, paradoxically, part of why it feels so consistent.
Battery Life: Bigger Cell, Shorter Runtime
One of the most counter-intuitive results in the Legion Go S vs Steam Deck battle: the Legion Go S has the larger battery (55.5Wh vs 50Wh) yet consistently lasts less time. In IGN’s standardized PCMark 10 battery rundown, the Steam Deck OLED managed 8 hours 8 minutes against the Legion Go S’s 6 hours 25 minutes – a 26% advantage for Valve despite a 10% smaller cell.
The reasons are structural. The Deck’s OLED panel draws less power than the Legion Go S’s larger, brighter, higher-resolution LCD; its APU is clocked conservatively; and SteamOS on the Deck is tuned to the exact hardware it runs on. Under heavy AAA load both devices converge – multiple reviewers reported both handhelds “tapping out” around 90 to 120 minutes when running demanding titles at full power. Light indie games and emulation can stretch the Deck past five or six hours; the Legion Go S trails in the same scenarios.
If portability away from a charger is your priority – flights, commutes, the couch with no outlet nearby – the Steam Deck OLED is the safer bet. If you mostly play docked or near power, the gap matters far less and the Legion Go S’s extra performance becomes the bigger story.
Ergonomics, Controls and the Missing Trackpads
Hold both devices and you immediately feel the design divergence. The Legion Go S is the larger, more console-shaped handheld with deep, contoured grips that many reviewers – PC World among them – praised as genuinely “ergonomic.” Its Hall-effect sticks resist drift, and the 8-inch screen makes menus and text easier to read. At about 730g it is roughly 90g heavier than the Deck, which you notice in long sessions.
The Steam Deck OLED’s signature feature is something the Legion Go S completely lacks: dual capacitive trackpads. They sound like a gimmick until you play a strategy game, an RTS, a point-and-click adventure, or navigate the Linux desktop – at which point they become indispensable. The Deck also has rear grip buttons and a control layout Valve has spent years refining. For mouse-driven genres and desktop work, the Deck is simply more capable; for traditional controller games, the Legion Go S’s bigger grips arguably feel better.
Net: if your library is strategy, simulation, or anything that benefits from a pointer, the Steam Deck OLED’s trackpads are a feature you cannot replicate on the Legion Go S. If you play action, racing and platformers with a standard pad, you will likely prefer the Lenovo’s grip.
SteamOS vs Windows: Why Lenovo Ditched Windows
The Legion Go S SteamOS edition, which began shipping in May 2025, is the first official non-Valve handheld to ship with SteamOS pre-installed – a landmark moment that signals Valve opening its OS to partners. The performance data above explains exactly why Lenovo bothered: the same Z2 Go hardware ran dramatically faster on SteamOS than on Windows 11, and the SteamOS SKU is cheaper to boot.
SteamOS delivers the console-like experience handheld buyers actually want: instant suspend/resume, a controller-first interface, per-game performance profiles, and no Windows update interruptions mid-session. The trade-off is compatibility. PC World cautioned that even on SteamOS the Deck offers a “smoother overall experience” because Valve has had years of polish, and that the Legion Go S could still hit snags with “text input, screen resolution adjustments, and control customization,” describing Linux driver compatibility on the device as “somewhat uncertain” at launch.
Anti-Cheat and Game Compatibility on Linux
Both SteamOS devices share the same Achilles’ heel: kernel-level anti-cheat. Competitive multiplayer titles that require anti-cheat systems not enabled for Proton/Linux will not run on either handheld. Before buying either device for a specific game, check its status on ProtonDB and Valve’s own Deck Verified program. Single-player libraries and the vast majority of Steam’s catalog run flawlessly; the risk is concentrated in a handful of live-service shooters.
Because the Legion Go S is newer to SteamOS, its hardware-specific quirks (fan curves, screen brightness controls, button mapping) were still maturing through 2025 via firmware updates, whereas the Steam Deck’s SteamOS is fully native. You can read Valve’s official compatibility guidance in the Steam Deck FAQ.
Thermals, Fan Noise and Build Quality
Both handhelds use a single-fan cooling solution, but they target different operating points. The Steam Deck OLED, capped in its 4–15W window, runs cool and quiet – Valve’s revised OLED cooling is noticeably better than the original LCD model, and fan noise rarely intrudes. The Legion Go S, designed to be pushed harder, ramps its fan more aggressively at 25W and above; that is the price of the extra frames. At matched 15W settings the two are comparable, but enthusiasts who chase the Legion Go S’s performance ceiling will hear about it.
Build quality is a wash at the premium end and tilts toward Lenovo at the budget end. The Legion Go S feels solid and modern, with a clean single-screen design (unlike the detachable-controller Legion Go 2). The Steam Deck OLED’s chassis is well understood after years on the market, with a deep accessory and repair ecosystem – Valve and iFixit sell official replacement parts, which is a genuine long-term ownership advantage the newer Legion Go S has not yet matched.
Storage, Docking and the Accessory Ecosystem
Both handhelds ship with replaceable M.2 NVMe SSDs (the Steam Deck uses the compact 2230 form factor; the Legion Go S also accepts a user-swappable drive), and both add a microSD slot for cheap library expansion. In practice, the 512GB base tier on either device fills quickly with modern AAA installs that routinely exceed 100GB, so a fast microSD card or a drive upgrade is a near-mandatory accessory regardless of which side of the Legion Go S vs Steam Deck debate you land on.
Docking is where Valve’s head start shows. The official Steam Deck Dock, plus years of third-party USB-C docks validated by the community, make couch-to-TV play a solved problem on the Deck, complete with external display output and wired peripherals. The Legion Go S works with standard USB-C docks too, and SteamOS handles external displays, but the catalog of guaranteed-compatible accessories is younger. If you plan to use your handheld as a part-time desktop or living-room console, the Steam Deck’s mature dock-and-accessory ecosystem is a quiet but real advantage.
One more practical note: because both devices run SteamOS, community tools like Decky Loader plugins and EmuDeck emulation front-ends install identically on each. That cross-compatibility means your customization investment carries over if you ever switch – another consequence of Valve opening SteamOS to partners.
5 Real-World Scenarios: Which Handheld Wins
Specs only matter in context. Here are five concrete usage patterns and the device that wins each, based on the benchmark and battery data above.
- Long flights and commutes: Steam Deck OLED. The 8h 8m PCMark battery result and efficient OLED make it the away-from-power champion.
- Demanding AAA games (Cyberpunk, RDR2): Legion Go S. With the TDP opened to 25W it nearly doubles the Deck’s frame rate in PC World’s testing.
- Strategy, sims and emulation front-ends: Steam Deck OLED. The dual trackpads and mature SteamOS make pointer-driven games and desktop tasks far easier.
- Bright outdoor / sunlight play: Steam Deck OLED. ~1000 nits HDR OLED beats the Legion Go S’s 500-nit LCD in direct light.
- Reading-heavy RPGs and crisp visuals: Legion Go S. The 8-inch 1200p 120Hz screen is bigger, sharper and smoother for text and UI.
A sixth scenario worth calling out: if you want the most powerful handheld regardless of price, skip both base models and look at the Z1 Extreme Legion Go S or rival flagships. For that tier, see our ROG Xbox Ally X vs Steam Deck OLED comparison and the Legion Go 2 vs Steam Deck breakdown.
Use-Case Recommendations: Who Should Buy Which
Five buyer profiles, five clear recommendations for the Legion Go S vs Steam Deck decision:
- The value-first newcomer: Steam Deck OLED 512GB at $549. Cheapest entry, best battery, most polished software, biggest community. The safest first handheld.
- The performance-hungry tinkerer: Legion Go S SteamOS (Z2 Go) at $599. $50 more buys a bigger 120Hz screen and a higher performance ceiling for those willing to manage TDP.
- The enthusiast who wants maximum frames: Legion Go S Z1 Extreme (~$829). A different class entirely – closer to a Legion Go 2 or ROG Xbox Ally X than to a Deck.
- The strategy/emulation player: Steam Deck OLED. The trackpads and mature Linux ecosystem are decisive for these genres.
- The Windows-only holdout: Neither SteamOS model – but note the $730 Windows Legion Go S exists if you genuinely need Game Pass desktop apps, even though reviewers found it slower and harder to justify.
Migration Guide: Moving From Steam Deck to Legion Go S (or Back)
Because both SteamOS devices live in the same ecosystem, switching between them – or running both – is refreshingly painless. Your Steam library, cloud saves, and purchases are account-bound, not device-bound. Here is the practical migration path:
- Confirm cloud saves first: enable Steam Cloud per game (Library → game → Properties → General). Cloud saves sync automatically across both handhelds.
- Sign in on the new device: log into the same Steam account on the Legion Go S or Deck. Steam Guard will prompt for two-factor approval.
- Re-download your installs: games re-download from your library; nothing needs re-purchasing. Use a microSD card to move large installs without re-downloading if both devices share the card format.
- Recreate per-game performance profiles: TDP and framerate profiles are device-local, so set them fresh (use 15W on the Deck, 20–25W on the Legion Go S as starting points).
- Reinstall non-Steam tools: if you used Decky Loader, EmuDeck or other community tools, reinstall them on the new device. See our guides below.
- Verify anti-cheat games: before assuming a multiplayer title works, check ProtonDB/Deck Verified status – it is identical across both SteamOS handhelds.
Because both run SteamOS, there is no operating-system relearning curve – the Quick Access Menu, library and settings are the same. This shared-OS reality is the quiet superpower of the SteamOS Legion Go S: it makes the two devices interchangeable rather than rival walled gardens.
Pros and Cons: Legion Go S vs Steam Deck OLED
Lenovo Legion Go S
- Pros: Bigger 8-inch 1200p 120Hz VRR screen; higher performance ceiling (especially Z1 Extreme); larger 55.5Wh battery; cheaper SteamOS SKU than its own Windows version; ergonomic grips; sharper 283 PPI panel.
- Cons: Shorter real-world battery life despite bigger cell; no trackpads; LCD lacks OLED contrast/HDR; SteamOS support newer and less mature; heavier at ~730g; louder fan at high TDP.
Valve Steam Deck OLED
- Pros: $549 entry price; best-in-class 8h+ battery; stunning HDR OLED at ~1000 nits; dual trackpads; most mature SteamOS; huge community, accessory and repair ecosystem; lighter and quieter.
- Cons: Lower 800p resolution and 90Hz refresh; older Zen 2 APU with a lower performance ceiling; smaller 7.4-inch screen; no VRR.
Expert Opinions: What the 2025 Reviews Concluded
The reviewer consensus split cleanly along the price-versus-power line. IGN came down on the side of the Lenovo, naming it “my favorite handheld gaming PC” and stating that “from performance to design, the Legion Go S is the better handheld gaming PC,” while explicitly conceding the Steam Deck keeps the edge “in price and battery life.”
PCMag focused on the SteamOS transformation, noting that the Windows build was “underwhelming” and that switching to SteamOS “nets significant gains” and “considerable performance improvements.” PC World took the opposite final stance: it measured a “20 to 40 percent” performance uplift over the Steam Deck depending on the game, praised the Legion Go S’s screen and ergonomics, but still chose the Steam Deck OLED for its “smoother overall experience,” warning that Linux driver compatibility on the Lenovo remained “somewhat uncertain.” The disagreement is the story – these are genuinely close devices optimized for different priorities.
Final Verdict: Which Handheld Wins in 2026?
After weighing every category, the Legion Go S vs Steam Deck verdict is genuinely use-case dependent – but the data points to a clear default. For most buyers in 2026, the Steam Deck OLED at $549 remains the better all-round value: it is cheaper, lasts dramatically longer on battery (8h 8m vs 6h 25m), has trackpads no rival can match, ships the most mature SteamOS, and is backed by the deepest ecosystem in handheld gaming. It is the device that does the most things well with the fewest caveats.
The Legion Go S SteamOS earns its $599 price for one specific buyer: the person who wants a bigger, sharper, faster screen and is happy to manage the TDP slider and accept shorter battery life to get there. At equal 15W power the two trade blows; with the slider opened up, the Legion Go S is unambiguously faster, sometimes by 50% or more. And the Z1 Extreme model is a different, higher-end conversation altogether.
The deeper takeaway is that Valve won the platform war even where it lost the hardware spec sheet: a Lenovo handheld running Valve’s operating system, undercutting Valve on the screen, is still measured against – and often beaten by – the Steam Deck on the things that make a handheld feel finished. SteamOS going multi-vendor is the most important story in this space, and the Legion Go S is its proof of concept.
Frequently Asked Questions
Is the Legion Go S better than the Steam Deck?
It depends on what you value. The Legion Go S has a bigger, sharper 8-inch 1200p 120Hz screen and a higher performance ceiling, especially at 25W TDP where it can be 50%+ faster. The Steam Deck OLED is cheaper ($549), has better battery life (8h 8m vs 6h 25m in IGN testing), includes dual trackpads, and runs the most mature version of SteamOS. IGN preferred the Legion Go S overall; PC World preferred the Steam Deck.
How much does the Legion Go S SteamOS cost vs the Steam Deck?
The Legion Go S SteamOS edition starts at $599 (Ryzen Z2 Go, 16GB RAM, 512GB). The Steam Deck OLED starts at $549 for 512GB and $649 for 1TB. The higher-end Z1 Extreme SteamOS Legion Go S sells for around $829, and the Windows version of the Z2 Go model costs $729.99.
Does the Legion Go S have trackpads like the Steam Deck?
No. The Steam Deck OLED has two capacitive trackpads, which are excellent for strategy games, point-and-click titles and desktop navigation. The Legion Go S has none – it relies on standard joysticks and face buttons. If you play pointer-driven genres, this is a meaningful advantage for the Deck.
Why is the SteamOS Legion Go S faster than the Windows version?
Windows 11 carries significant background overhead that handheld hardware struggles to absorb. SteamOS is a lean, gaming-focused Linux build with less overhead, so the same Ryzen Z2 Go hardware ran far faster on SteamOS – the WindowsForum roundup measured a The provided sources support a SteamOS uplift of about **56%** in Legion Go S testing, and the exact **69%** and **121%** over Windows builds are not substantiated by the supplied results.
Which has better battery life, Legion Go S or Steam Deck OLED?
The Steam Deck OLED, despite a smaller 50Wh battery versus the Legion Go S’s 55.5Wh. In IGN’s PCMark 10 test the Deck lasted 8 hours 8 minutes versus 6 hours 25 minutes for the Legion Go S. Under heavy AAA load both converge to roughly 90–120 minutes.
Can both devices play the same games?
Yes – both run SteamOS and access the same Steam library with shared cloud saves. The only compatibility limits come from kernel-level anti-cheat in certain competitive multiplayer titles, which affects both devices identically. Check ProtonDB or Deck Verified status before buying for a specific game.
Is the Legion Go S SteamOS the first non-Valve SteamOS handheld?
Yes. The Legion Go S SteamOS edition, which began shipping in May 2025, is the first official third-party handheld to ship with SteamOS pre-installed, marking Valve’s move to license its operating system to hardware partners.
Should I wait for a Steam Deck 2?
Valve has signaled it will not release a Steam Deck 2 until there is a generational leap in performance-per-watt, so a true successor is not imminent as of mid-2026. If you want a handheld now, the Steam Deck OLED and Legion Go S SteamOS are both excellent and will stay relevant for years.
