Asus ROG Xbox Ally X20 tested: Same performance, more comfortable, and a glorious OLED screen

For Asus ROG's 20th birthday, the company released a slew of computer parts (enough for a supremely expensive build). But it's not overlooking its more recent entry into gaming handhelds, with the new Asus ROG Xbox Ally X20, a revamped version of the Asus ROG Xbox Ally X, which is already one of the best handheld gaming PCs.

The $1,299.99 gaming handheld ($2,499.99 if you get it in a bundle with XR glasses, a Pelican case, and a Dbrand Killswitch case) doesn't change performance at all. Instead, it makes some common-sense tweaks to its existing $999.99 handheld, adding TMR joysticks, rubberized grips, a see-through design, a transforming D-pad, and, most importantly, an OLED display.

If you already have an Ally X, this isn't a reason to upgrade. But if you're looking to get into handheld PC gaming and are willing to splurge, the changes here sure are nice.

Design and Display on the Asus ROG Xbox Ally X20

If you put the Asus ROG Xbox Ally X20 and the original next to each other, it's impossible not to notice the differences. But still, these are largely the same system, inside and out. They have the same button layout, the same grips, the same screen size, speaker placement, and vents.

The most visible difference is that the X20 has a new, transparent plastic case with a black tint, along with gold menu buttons, a gold stripe across the back (rather than silver), and a large "20th Anniversary" ROG badge on the rear. I prefer the original Xbox Ally X's plainer design; the clear plastic looks more like a toy. I also found that it let the status lights shine through the top of the system, just abover the screen, which is distracting.

There is one minor change in the menu buttons: where the Ally X had a library button, the Ally X20 has a screenshot button. It's more useful in general, but it's also a great way to accidentally take a screenshot.

But once I picked up the Ally X20, the original couldn't compare. The chassis feels more substantial, especially with rubberized grips on the back of the prongs. There's a new directional pad, which feels more substantial; it also twists between a 4-way and 8-way pad, though I found switching between these two modes quite awkward. The 8-way D-pad is better for fighting games, while the 4-way with more distinct cardinal directions will make more sense for action-adventure and platform games.

The new TMR joysticks, which should show less wear with age, feel tighter. All of this adds up, even though there is no performance difference between the two devices. They share the same AMD Ryzen AI Z2 Extreme chip.

The other big change is the screen. Both use 1920 x 1080 touchscreens, but the Xbox Ally X20 has a 7.4-inch OLED panel, slightly larger than the original's 7-inch IPS display. While the screen size isn't much of a difference, the narrower top bezel is noticeable.

And the OLED screen looks great. It's only slightly more vivid on measured color tests. But it's definitely brighter, and it's absolutely an improvement. The OLED screen doesn't measure as well as the OLED screen on the Steam Deck OLED, but in isolation, I thought Asus's panel looked great, and it has a much more recent chip than the Steam Deck.

Forza Horizon 6 looked beautiful, with lush greenery on the sides of tracks and realistic, colorful paint jobs. In God of War: Ragnarok, dark areas with deep blacks made dim light stand out.

Battery Life on the Asus ROG Xbox Ally X20

The Ally X20 has the same 80 Whr battery as its predecessor. To get an idea how long you can play a demanding game for, I booted up God of War: Ragnarok, set the screen to 50% brightness, and used the 17W performance mode. With the game running on low settings with AMD FSR 3.1.4 at 720p, the machine had 47% charge left after an hour and 15 minutes of gameplay.

That suggests that I could have hit about 2.5 hours had I kept going. That's down from about 3 hours on the original Ally, though it's not apples to apples, as I played different games. It's to be expected that an OLED display would use a bit more power, however.

Software and Warranty on the Asus ROG Xbox Ally X20

The ROG Xbox Ally X20 uses the same Full Screen Experience that the original Xbox Ally X originated. Portions of Windows don't even load unless you switch to desktop mode, which saves RAM and helps boost performance.

For some features, Asus includes Armoury Crate SE. That's where you can make changes to the lighting around the joysticks, adjust power management (whether in the app or in the Xbox menu), and calibrate your joysticks and triggers.

Asus sells the ROG Xbox Ally X20 with a 1-year warranty.

Bottom Line

The Asus ROG Xbox Ally X20 is the definitive form of Asus' handheld. It feels better in the hands, has joysticks that should last longer, and the OLED display is a noticeable improvement.

All of that being said, games play the same across the two devices. If you already have an original ROG Ally X, this isn't worth the upgrade. You won't get any more performance, and the IPS screen on the original is still plenty bright and colorful, even if the blacks aren't as good as on an OLED screen.

If you're buying a new machine, it's a tougher choice. The X20 is $1,299.99 — a $300 increase over the original, which is staying on the market. If this is your sole gaming machine, that may be worthwhile for the improved screen, TMR joysticks, and a slightly more solid build. But it's a lot of money; the original Xbox Ally X will play games the same way for $300 less. Neither will play games as well as the Intel Arc G3, but the only system with that available right now is $1,799.

The X20 is worth getting if it's going to be your only gaming PC for a few years. The $1,299.99 price is high for a handheld, but given that the $999.99 version is effectively the best deal in handhelds right now, it makes some sense to invest if you want the best experience.
