Round by round
Performance
Winner: ASUS ROG Xbox Ally X (2025)The Xbox Ally X is comfortably the more powerful machine: its Ryzen AI Z2 Extreme (8 cores/16 threads) and 24GB of RAM push modern AAA games at higher frame rates and settings than the Steam Deck OLED's older 4-core Zen 2 / RDNA 2 APU, which was tuned for efficiency rather than raw grunt. If you want to play the newest releases at 1080p, the Ally X wins clearly.
Display
Winner: Steam Deck OLEDThe Steam Deck OLED's 7.4-inch HDR OLED panel (up to 1000 nits) is the nicer screen to look at - deep blacks, vivid colour and HDR the Ally X's 1080p IPS LCD can't match. The Ally X answers with higher 1920x1080 resolution and a 120Hz refresh rate, so it's sharper and smoother, but for most handheld gaming the OLED is more pleasant.
Battery life
Winner: ASUS ROG Xbox Ally X (2025)The Ally X's 80Wh battery is far larger than the Deck OLED's 50Wh, and it offsets the hungrier chip well - in demanding AAA sessions the Ally X generally lasts longer. In lighter indie and 2D games the Steam Deck OLED's efficiency keeps it competitive, but on raw capacity and heavy-load endurance the Ally X takes it.
Software & ecosystem
TieFull Windows 11 plus the new Xbox full-screen experience means the Ally X runs Game Pass, Steam, Epic, Battle.net and emulators out of the box - at the cost of occasional desktop-Windows friction. SteamOS is the more polished, console-like handheld OS with superb resume/standby, but anything outside Steam needs Proton or Linux tinkering. It's a genuine trade-off, so this one is a tie.
Value & AU availability
Winner: Steam Deck OLEDAt AU$1,799 the Ally X is the premium option and is JB Hi-Fi-exclusive here - it isn't sold on Amazon AU at all. The Steam Deck OLED starts at AU$1,199 (512GB) direct from Valve, so it's several hundred dollars cheaper, though it has no first-party local retail and Amazon AU only carries marked-up third-party listings. On price the Deck wins; on local buy-in-store convenience the Ally X has the edge.
Pros & cons
ASUS ROG Xbox Ally X (2025)
- +Most powerful of the two: AMD Ryzen AI Z2 Extreme (8 cores/16 threads) with a ~50 TOPS NPU
- +Huge 80Wh battery and 24GB LPDDR5X RAM
- +Full Windows 11 plus the new Xbox full-screen experience: Game Pass, Steam, Epic, any launcher and emulators
- −Expensive at AU$1,799 after 2026 price hikes, and JB Hi-Fi-exclusive (no Amazon AU stock)
- −7-inch 1080p IPS LCD (500 nits) can't match the Deck's OLED contrast
- −Heaviest of the two at 715g, and the Windows handheld experience is still rougher than SteamOS
Steam Deck OLED
- +Gorgeous 7.4-inch HDR OLED display (up to 1000 nits) - easily the best screen here
- +Cheaper entry at AU$1,199 with superb SteamOS polish, fast resume and standby efficiency
- +Lighter at ~640g, and excellent battery efficiency in lighter games
- −Much less powerful APU (4-core Zen 2 / RDNA 2) - struggles with the newest AAA games at high settings
- −Lower 1280x800 resolution at 90Hz
- −No first-party AU retail - Valve-direct only; non-Steam stores need Proton/Linux tinkering

Verdict - who should buy which
These two handhelds answer the same question in different ways. The ROG Xbox Ally X is the powerful, do-anything Windows machine wrapped in a comfortable Xbox-branded shell; the Steam Deck OLED is the refined, better-value, console-like option with a far nicer screen. After 2026's AU price rises both are pricey, so the decision comes down to whether raw power and storefront freedom matter more to you than display quality, value and a polished experience.
Buy ASUS ROG Xbox Ally X (2025) if - you want the fastest handheld, play the latest AAA games, rely on Game Pass or non-Steam launchers, and are happy to pay AU$1,799 at JB Hi-Fi for a Windows device.
Buy Steam Deck OLED if - you want the best screen and the most polished experience, mostly buy on Steam, and would rather spend from AU$1,199 than chase maximum performance.
For the typical Australian buyer the Steam Deck OLED is the easier recommendation on value and experience - but if you're a power user who wants the headroom, the NPU and full Windows flexibility, the ROG Xbox Ally X earns its premium.
