ROG Xbox Ally vs. Steam Deck OLED: Screen Quality, Software, and User Experience

A detailed comparison highlighting performance differences, battery behavior, and real-world usability between Steam Deck OLED and ROG Xbox Ally.

Comparing the Steam Deck OLED and the ROG Xbox Ally reveals significant differences in value, performance, software, and ease of use. Although handheld gaming devices appear comparable in price and purpose, their real-world performance and user perceptions differ substantially. For most people, the Steam Deck OLED is just the superior choice.

If you're choosing between the Steam Deck OLED and the ROG Xbox Ally, 99% of people should get the Steam Deck OLED. The 1% who might want the Xbox Ally are those who want to reply to a Microsoft Teams pop-up while gaming. Other than that one guy, the Steam Deck OLED is cheaper, has a better screen, way better software, better battery life, better performance in every game tested despite using less wattage, and it comes with a carrying case.

The Xbox Ally is $600, and the Steam Deck is $550. Because they're similar in pricing, cross-shopping is going to happen. There might be a very specific person who still wants the Xbox Ally, but that person might not even exist. Despite Microsoft's marketing, this is not an Xbox. It is a Windows PC, as indicated by the lock screen.

If someone buys this thinking it's an actual Xbox, they are going to have a bad time. If someone wants to use Microsoft Excel with joysticks, it's preinstalled, but it doesn't work with them.

Performance Testing

We ran all performance testing at the highest wattage on both devices: 20W on the Xbox Ally and 15W on the Steam Deck OLED, at 720p and 800p, respectively. In Red Dead Redemption 2, with everything set to low, the Xbox Ally hit 37fps with a 1fps minimum. Under the same conditions, the Steam Deck OLED hit 49 fps, with a minimum of 28 fps, for a 32% faster average. The significantly higher minimums reduce stutter and improve stability.

In Cyberpunk, using the Steam Deck preset, the Xbox averaged 43fps while the Steam Deck OLED averaged 47fps, about 9% faster. In Elden Ring, both hovered between 40–45fps, with the Deck generally 5fps higher. In Space Marine 2, with everything set to low, the Xbox got about 15–30fps, while the Steam Deck OLED hit about 25–40fps, which is roughly 60–80% faster.

Across all tests, the Xbox Ally never once outperformed the Steam Deck OLED. This was surprising because they share the same Z2A chip, with the Xbox drawing 5 more watts. The explanation is Windows. Windows remains inefficient for gaming handhelds, while SteamOS is significantly lighter and better optimized. The same pattern was seen on the Legion Go and Legion Go S. SteamOS simply does not waste resources on background tasks like Windows does.

For users still wanting Windows performance on the Ally, installing Bazite—essentially a way to install SteamOS on Windows handhelds—is an option. It dramatically improves efficiency.

Battery Life Differences

Battery life testing used a worst-case scenario: Elden Ring, max settings, max brightness, uncapped framerate, maximum TDP. The Steam Deck OLED ran at 15W, the Xbox at 20W. Even with the Xbox's larger 60Wh battery compared to the Deck's 50Wh, Steam Deck OLED lasted 2h27m, while the Xbox lasted only 1h40m.

That's a 45-minute difference in favor of the Steam Deck, all while running a bigger, brighter screen and slightly better performance. This makes the Xbox's optimization issues difficult to ignore.

Hardware Design and Ergonomics

Both devices have excellent ergonomics. The Xbox Ally feels like a wider Xbox controller, which can actually be more comfortable for elbows and shoulders when held outward. The Steam Deck's trackpads remain a standout feature. At the same time, we don't use them for every game; they are extremely useful for specific genres and navigating Windows. Their absence on the Ally makes Windows navigation less convenient.

The Ally's back paddles are small and harder to press, and it has only two compared to the Steam Deck's four larger ones. We found occasional button-sticking on the Ally's ABXY buttons during button-mashing, resulting in missed inputs.

The Ally has two USB-C ports, which is convenient, though neither device easily supports external GPUs without significant effort. The Ally X, however, does support external GPUs.

Display Comparison

Side-by-side, the Xbox Ally screen looks familiar. In contrast, the Steam Deck OLED looks vivid and striking, offering much stronger contrast and brightness. The Xbox Ally supports 120Hz, 1080p, and VRR. The Steam Deck OLED offers 800p and 90Hz, but has a 20% larger screen at 7.4 inches compared to the Ally's 7 inches, thanks to smaller bezels.

The Steam Deck reaches 1000 nits of HDR brightness, compared to the Ally's 500 nits. Colors and contrast are significantly better on OLED.

While higher resolution and refresh rate sound better on paper, the chip cannot realistically drive most games at 1080p or 120Hz. Running a 720p image on a 1080p screen results in non-pixel-perfect scaling and a softer look. Running 720p on a native 720p panel looks sharper.

VRR, which the Steam Deck lacks, looks smoother, especially in unstable-framerate scenarios.

As cloud gaming grows—especially with GeForce streaming—screen quality becomes increasingly important. Ergonomics and Wi-Fi are strong on both devices, but the Ally's middling screen holds it back.

Software Experience

SteamOS on the Steam Deck feels like a polished console experience with optional tinkering for those who want deeper customization. Windows on the Ally remains clunky on a handheld. Despite Microsoft's marketing, you still need to interact with Windows frequently.

Updating the Steam Deck is simple: one settings menu. Updating the Ally requires navigating four areas, each with its own set of update types. This adds confusion and introduces unnecessary friction.

Using multiple game launchers, like Steam, Epic, Origin, and Battle.net, is easier on Windows, and that is one area where the Ally shines. Although we can run them all on the Steam Deck, it requires more setup.

Software Bugs and Reliability

Frequent software bugs continue to affect Ally. The fingerprint reader didn't work out of the box because the required drivers were missing. Even after fixing it, it often stops working. At times, the PIN entry screen does not register input, requiring a full reboot. Many games launch with the on-screen keyboard open, and it cannot be dismissed with the controller. The Ally also dims the screen when unplugged, and the setting to fix this is buried deep in Windows system settings rather than in Armory Crate or the Xbox Experience menus.

These overlapping software layers create a confusing mess. While most issues resolve after a restart, rebooting multiple times a day ruins the experience.

Who the Xbox Ally Is For

It is difficult to find a user who truly benefits from the Ally over the Steam Deck OLED. The main exception would be someone who exclusively plays games like Fortnite, Destiny 2, or newer Call of Duty titles that use anticheat systems incompatible with SteamOS. These can still be played on the Steam Deck using streaming services like GeForce Now or by dual-booting Windows, but if someone insists on native play, the Ally can do it.

Even then, buying a used ROG Ally X or an older ROG Ally model offers better performance and value than the new Xbox Ally.

The Xbox Ally offers poor overall value due to worse performance, worse battery life, a smaller, dimmer screen, and significantly worse stability.
