Currency Check
As of October 2026, verified: the Steam Deck OLED is sold by Valve, and Valve’s own spec page lists a 7.4-inch OLED, 16GB of memory and a 50Wh battery. ASUS’s spec page lists the ROG Ally X with an 80Wh battery and 24GB of memory. ASUS also launched the Windows-based ROG Xbox Ally X on October 16, 2025, and sources disagree on whether the original ROG Ally X is still stocked. A Steam Deck 2 has not been announced; reported release dates are rumor only. Handheld prices have moved repeatedly this year, so check current listings.
The Steam Deck OLED is the better pick if you want the best screen, a console-like experience and long battery life in lighter games, while the ROG Ally X is the better pick if you want a faster chip, a sharper 120Hz display and the freedom of Windows. Neither is universally better, and the right choice depends on your library, your storefronts and how you use the handheld. This guide compares the verified specs, explains the trade-offs, and then shows how three docks fit either device.

| Your situation | Our verdict |
|---|---|
| Your library is mostly on Steam and you want a simple, console-style experience | Steam Deck OLED. SteamOS is built around that library, and the HDR OLED screen is its biggest hardware edge. |
| You use several storefronts, subscription services or Windows-only launchers | ROG Ally X. It runs Windows 11 Home, so launchers install the way they would on a PC. |
| You play demanding newer titles and want more raw hardware | ROG Ally X has the stronger chip on paper: 8 cores and 12 graphics compute units against 4 cores and 8 compute units. |
| You play indie, 2D and older games for hours at a time | Steam Deck OLED. Its lower-power chip and OLED panel suit lighter loads, according to Valve’s battery description of 3 to 12 hours. |
| You plan to dock it to a TV or monitor most evenings | Either works. Pick the handheld first, then check the dock listing for compatibility with that exact model. |
The Key Differences
All specs below come from Valve’s Steam Deck tech specifications page and ASUS’s ROG Ally X specification page. Where a figure depends on the exact configuration, that is stated.
| Spec | Steam Deck OLED | ROG Ally X |
|---|---|---|
| Display | 7.4-inch HDR OLED, 1280 x 800, up to 90Hz | 7-inch IPS-level, 1920 x 1080, 120Hz |
| Peak brightness | 1,000 nits HDR peak, 600 nits SDR (Valve) | 500 nits (ASUS) |
| Processor | 6 nm AMD APU, 4 Zen 2 cores and 8 threads | AMD Ryzen Z1 Extreme, 8 cores and 16 threads |
| Graphics | 8 RDNA 2 compute units | 12 compute units (ASUS) |
| Memory | 16GB LPDDR5 on board | 24GB on board (two 12GB LPDDR5 chips per ASUS) |
| Storage | 512GB or 1TB NVMe, plus microSD | 1TB NVMe M.2, plus microSD |
| Battery | 50Wh | 80Wh |
| Weight | About 640 grams | 678 grams |
| Operating system | SteamOS | Windows 11 Home |
| Wired ports | USB-C with DisplayPort, USB 3 Gen 2 | USB4 with Thunderbolt 4 support, USB 3.2 Gen 2 Type-C |
Screen: OLED contrast against a sharper, faster panel
The Steam Deck OLED’s screen is larger at 7.4 inches, with a contrast ratio Valve lists above 1,000,000 to 1 and HDR support. The ROG Ally X’s panel is smaller but sharper, with 1920 x 1080 pixels and a 120Hz refresh rate, which helps in fast games where the hardware can deliver those frame rates. At 1280 x 800 the Deck is driving fewer pixels, which suits its chip. The honest trade is picture quality in the Deck’s favor and resolution and refresh rate in the Ally X’s favor. Whether 120Hz matters depends on whether the games you play can reach it on the Ally X’s hardware.
Chip and power: on-paper strength against efficiency
On the spec sheet, the Ally X has the stronger processor: eight cores and sixteen threads against four cores and eight threads, and 12 graphics compute units against 8. Press comparisons generally conclude the Ally X delivers higher frame rates in demanding games, though the size of the gap depends on the title and power mode, and this article does not quote frame rates. The Deck’s lower-power design trades peak performance for efficiency, and it can run lighter games for long stretches. More chip does not automatically mean a better experience; it means more headroom in games that need it.
Battery: capacity against actual runtime
The Ally X’s 80Wh battery is 60 percent larger than the Deck’s 50Wh, which is simple arithmetic from the spec pages. Runtime does not scale with capacity alone, because the Ally X’s chip draws more power in demanding games. Valve describes 3 to 12 hours of gameplay for the Deck, a wide range that reflects how much the game and settings matter. For the Ally X, ASUS lists capacity but runtime depends on the power mode you choose. Compare your own typical sessions rather than relying on a headline number.
Software: SteamOS against Windows
The Steam Deck runs SteamOS, which boots into a controller-friendly interface built around the Steam library. Games that work well are labeled by Valve’s compatibility program, and many non-Steam stores can be installed with extra steps. The ROG Ally X runs Windows 11 Home with ASUS’s Armoury Crate software, so launchers such as those for other storefronts install normally, and some anti-cheat systems that block Linux work on Windows. The cost is a desktop operating system on a small touchscreen, which often means more fiddling to get a console-like experience. Pick based on where your games live.
Docking and accessories
Both devices have a USB-C port that can output video, so a dock with an HDMI port, Ethernet, USB ports and power input turns either into a small desktop console. Valve’s page says the Deck’s USB-C supports DisplayPort output up to 4K at 120Hz, but whether a given dock passes that depends on its chipset and HDMI version. Many handheld docks use HDMI 2.0, which tops out at 4K at 60Hz. Check the dock listing for your specific handheld, because some dock listings explicitly exclude certain models, and case thickness can stop a handheld from seating in a cradle-style dock.
How to Decide
- List your top five games. Check whether each runs well on SteamOS through Valve’s compatibility labels, and whether any need Windows-only launchers or anti-cheat.
- Estimate session length. If most sessions are over two hours away from an outlet, compare the 50Wh and 80Wh batteries against your games, not against a generic number. Rule of thumb: heavier games shorten runtime on both devices.
- Decide how much you dock. If you play mainly on a TV, battery matters less and the chip and dock matter more.
- Weigh the screen. If you value black levels and HDR, the OLED is the draw. If you prefer sharpness and 120Hz, the Ally X is.
- Check storage. The Ally X lists 1TB. The Deck comes in 512GB or 1TB, and both take microSD cards for extra space.
- Factor in uncertainty. A Steam Deck 2 is only rumored, and the Ally X lineup may be superseded by the Xbox Ally X. Neither fact changes what the device in front of you does today.
A worked example: you play indie games and older Steam titles on trips, with sessions of three hours or more. The Deck’s efficiency and screen fit that use. If instead you want to run a Windows-only launcher and play heavier new releases docked at 1080p, the Ally X’s extra cores and Windows environment are the better fit.
Products That Fit
The docks below are accessories for either handheld, listed as examples that fit the docking situation above and not as a ranking. Compatibility varies by listing, so confirm that your exact model is named before buying.
Anker 6-in-1 Steam Deck Dock – suits a Steam Deck owner who wants a simple TV setup
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
This dock is named for the Steam Deck, so it is the clearest fit for a Deck owner who wants one cable to a TV. It adds wired Ethernet, which helps online play and large downloads, and passes through power so the handheld charges while docked. If you own an Ally X, check the listing’s compatibility notes first, since dock listings for this category sometimes exclude certain Windows handhelds.
- 6-in-1 hub with a 100W power delivery input and a 4K at 60Hz HDMI output
- 1Gbps Ethernet port and two USB-A ports at 5Gbps each
- One USB-C data port at 5Gbps; the listing notes it does not support screen mirroring
- Built-in 8.66-inch USB-C cable and an 18-month warranty
Caveat: the output is capped at 4K 60Hz, so it will not give you a higher refresh rate on a capable display.
6-in-1 Docking Station for OLED, ROG Ally, Legion Go and MSI Claw – suits owners of more than one handheld
This dock lists several handhelds by name, including the Steam Deck OLED, ROG Ally, Legion Go and MSI Claw, which makes it a reasonable fit if you might switch devices or share the dock. It has the same HDMI 2.0 and Ethernet basics as the first example, with a longer replacement window.
- HDMI 2.0 output at 4K 60Hz and a Gigabit Ethernet port
- 100W PD 3.0 input for charging in higher-power modes
- Multiple 5Gbps USB 3.0 ports
- Listing mentions 3-year replacement coverage
Caveat: the listing names the ROG Ally but not the Ally X specifically, so confirm Ally X support on the page. Port count and cable details are in the full listing, so confirm there.
JSAUX 5-in-1 Docking Station – suits a player who wants a higher-refresh dock
This dock stands out for its HDMI 2.1 output with a stated 4K at 120Hz, which matters if you dock to a monitor or TV that supports that refresh rate. The listing names the Steam Deck LCD and OLED, ROG Ally and Ally X, Legion Go and Go S, and MSI Claw, so it covers both devices in this comparison.
- HDMI 2.1 output listed at 4K 120Hz
- 100W PD charging input and a wired Ethernet port
- Two USB-A 2.0 ports, which are slower than USB 3 ports
- Listing says it is not for the ROG Xbox Ally or Xbox Ally X
Caveat: whether your handheld can actually send 4K 120Hz through the dock depends on the device, so treat the figure as the dock’s capability, not a guarantee. Dock listings also note that the Ally X may need to be used without a thick case to seat properly.
Common Mistakes
- Choosing by processor alone. Battery, screen, software and the games you own affect daily use more than raw core counts.
- Assuming every dock works with every handheld. Check that your exact model is named, and whether cases fit.
- Paying for HDMI 2.1 without checking the display. A 4K 120Hz port only helps if both the handheld and the screen support it.
- Ignoring the USB-C data port on a dock. Some docks state that port carries data only and does not output video.
- Waiting for a rumored Steam Deck 2. It has not been announced, and rumored timelines are not confirmed.
- Skimping on the charger. A dock’s 100W figure describes its maximum input, so use a power supply that can feed it.
Buy Now or Wait?
- Buy now if you want a handheld today and the Deck or Ally X already fits your library.
- Wait only if you specifically need a feature neither device has, such as a newer chip, and accept that no new Valve handheld is confirmed.
- Check current stock and price on the retailer page, since both change often.
- Buy the dock after the handheld, not before, so you can confirm compatibility.
Questions
Is the Steam Deck OLED faster than the ROG Ally X?
No. On the spec sheets, the Ally X has the stronger processor and graphics, with 8 cores and 12 compute units against the Deck’s 4 cores and 8 compute units. The Deck’s advantages are its OLED screen, efficiency and SteamOS.
Which has the better battery?
The Ally X has the larger battery at 80Wh against 50Wh. Actual runtime depends on the game, brightness and power mode, and the Deck can last longer in lighter games because its chip draws less power.
Can I install non-Steam games on the Steam Deck?
Yes, with additional steps. Many other storefronts can be installed on SteamOS, but compatibility varies by game, and some anti-cheat systems do not support it. Windows on the Ally X avoids that limitation.
Do I need a dock?
No. Both handhelds can output video over USB-C with a simple adapter. A dock adds Ethernet, extra USB ports and charging in one cable, which is convenient if you play on a TV regularly.
Will a dock give me 4K at 120Hz?
Only if the dock, the handheld and the display all support it. Many docks use HDMI 2.0 and stop at 4K 60Hz, and a dock that advertises 4K 120Hz is describing its own capability, not your handheld’s.
Is the ROG Ally X the newest ASUS handheld?
No. ASUS launched the ROG Xbox Ally X in October 2025 as a newer Windows handheld, according to press coverage. Sources disagree on whether the original Ally X remains on sale, so confirm availability.
