Asus ROG Xbox Ally review: The cheapest Windows handheld gets points for showing up

With the Steam Deck OLED in and out of stock, should you consider going the Windows route instead?

Tom's Hardware Verdict

The Asus ROG Xbox Ally has an appealing price point and a comfortable design, but it has sleep/wake issues and doesn't offer better performance than the Steam Deck OLED. But it is regularly in stock, which the Steam Deck is not these days.

Reasons to buy

  • +

    Comfortable, ergonomic design

  • +

    Xbox Full Screen experience is better than Windows 11

  • +

    By far the most affordable modern Windows gaming handheld

  • +

    Can be found in stock

Reasons to avoid

  • -

    Issues with sleep/wake functionality

  • -

    Screen not as good as Steam Deck OLED

  • -

    Performance isn't much better than than a 3-year old Steam Deck OLED

  • -

    No carrying case included, and white chassis can get dirty

Gaming handhelds aren't affordable anymore. Many of them go for $999 or more. And, crucially, the Steam Deck OLED, the best handheld gaming PC and a price leader at $549, has mostly been out of stock as the component crisis continues.

That makes it a great time to look at the Asus ROG Xbox Ally, a $599 Windows-based option with, spoiler alert, a chip that looks a lot like the one in the Steam Deck – at least on paper. The Ally shares a lot in common with the far more expensive ROG Xbox Ally X, but it's still distant enough from the Steam Deck, and has a few technical issues that makes it still feels compromised.

    Sadly, it's a dumbed down POS. Having Xbox FSE is not something to sing about. It's an absolute waste of time. I played around with it for a bout 1hr, as I had it through a Windows Insider Preview build. It's identical in everyway to simply having the non FSE Xbox app open in front of you.

    Now, If you want a really good GUI for a purely gaming centric device (which my main PC is), then you don't need to look any further than Steam Big Picture mode. It's everything the Xbox FSE wants to be, but will never get there. Steam BPM is so well known, but it's because it's a refined and thoughtful piece of software that 'just' works as intended., If I had an Xbox Ally/X I would disable FSE, and just ruin steam. It's a much better experience.

    "The 7-inch, 1920 x 1080, 120 Hz touch screen on the ROG Xbox Ally is surprisingly decent for a standard LED panel.

    In Resident Evil Requiem, the screen, even at 40% brightness, was enough for me to see enough of the Rhodes Hill Chronic Care Center's west wing to sneak around. And yes, there was plenty of crimson red blood when some Infected broke out the chainsaws.

    On our meter, the Ally covered 85.4% of DCI-P3 volume and 120.6% of sRGB volume. Notably, both of those numbers are a bit higher than the screen on the Asus ROG Xbox Ally X, which is the same on paper. But the regular Ally measured 488.8 nits, which is a bit dimmer than the Xbox Ally X at 515.8 nits. These differences suggest that Asus might have separate sources of displays, with some differences.

    Either way, the Ally doesn't touch the Steam Deck OLED's screen, which is way more vivid and, at a max of 597.2 nits, significantly brighter." -From the above article
    There are so many things wrong with these comparisons that are not considered at all... The perceived brightness of one screen over another depends on many variables. Let's get the lesser known but important misconceptions out of the way first.

    1) If you have two screens that are equal in every respect except brightness measured in nits, and one screen is 500 nits and the other is 1000 nits; what do you think would be the perceived increase in brightness?

    The answer is about 35% brighter to the eye. The eye does not perceive brightness increased linearly like the stats may imply. Perceived brightness often follows Stevens' Power Law, which means that to perceive a doubling in brightness, you typically need quadruple the physical light output.
    2) If both screens have 1000 nits brightness and all else is equal but their diagonal measurement where one is 55 inches and the other 75 inches; which screen is perceived as brighter?

    If you thought that the larger screen looks brighter, you are correct. This is because of the volume of light increased substantially between the sizes of screens. This is measured as lumens or flux as compared to nits which is a measurement of light density.
    3) If both screens have 1000 nits brightness and all else is equal except one has much higher color saturation of 115% of the DCI-P3 color space and the other has 75% color saturation of the DCI-P3 color space; which screen is perceived as brighter?

    The answer would be the screen with the higher color saturation. This is called the Helmholtz-Kohlrausch Effect. More intensely saturated colors, particularly in the red and blue spectrum are perceived by the human eye as being brighter even with the same exact luminance across both screens.
    4) If both screens have 1000 nits brightness and all else is equal except one has much higher contrast at infinite, like an OLED, and the other has a contrast ratio of 1:1000; which screen is perceived as brighter?

    The answer would be the screen with infinite contrast ratio even at the same luminance. This is because the deeper blacks produced by higher contrast screens create a larger perceived gap in brightness between lighter and darker areas on the screen.
    5) If both screens have 1000 nits brightness and all else is equal except the amount of ambient light in the room is different for both screens; for example, one screen is perceived at night in a room with no other lights on and with blackout curtains on all windows, and the other is during mid day outside on a patio with the sun directly on the screen. In that scenario, which screen would look brighter?

    The screen shown in the dark room at night would look massively more bright than the other. This is because the difference between the ambient light in the room and the brightness of the screen greatly affects perceived brightness. The closer the ambient light is to the brightness of the screen, the more washed out and dull it will look.
    6) Lastly, if both screens have 1000 nits brightness and all else is equal except the image shown on both screens is for different durations of time where one screen flashes white for 1/20th of a second and the other for 1 seconds; which screen would be perceived as brighter?

    The screen that is flashed more briefly would be perceived much less bright than the screen that flashed for a full second. This is because of Bloch's Law. Very basically, your eyeballs are like a camera in that it needs sufficient exposure time of the light or luminance information is lost, thus making the image appear less bright. Brief flashes of light may feel more intense even though they look less bright because it takes the eye 200-500 milliseconds to adjust. While the pupil is still wide and unconstricted it can seem like a punch to the face if the quick flash of light is bright enough.

    Sleep/Wake is absolutely crucial for a handheld. If you cannot get that right then the entire product is a failure IMO.
    This isnt hyperbole for me as I use it every single time I touch my Steam Deck.

    Throw in the abysmal performance and this product is just flat out embarrassing.

    I mean, you can install Steam OS on them.
