Large-Screen Versatility or Compact Portability? ONEXPLAYER 3 vs. X2 Mini Pro

Both of these devices carry an 8.8" screen at 144Hz with VRR, so the choice between them was never going to come down to display size. It comes down to what each one asks you to prioritize once you're past the spec sheet: how the chip approaches performance, how the battery is built, and how far each one is willing to grow into a workstation versus stay a dedicated handheld.

Two philosophies wearing the same screen size

ONEXPLAYER 3 runs Intel's Arc G3 Extreme platform and leans on XeSS 3.0 multi-frame generation to multiply frame rate, an approach that trades some native responsiveness for higher displayed frame rates in demanding titles. X2 Mini Pro runs AMD's Ryzen AI Max+ 388 with the 40-CU Radeon 8060S, the same graphics engine found in ONEXPLAYER's tablet-class devices, an approach built to hit target frame rates natively rather than generate frames to reach them. Neither is objectively better, they're different bets on how to spend the same power budget.

Battery philosophy: built-in versus swappable

ONEXPLAYER 3 carries an 85Wh battery built into the chassis, tuned around its 8W-35W adjustable TDP range. X2 Mini Pro also uses an 85Wh cell, but it's external and swappable, following the same design language as APEX. That difference matters most for anyone doing back-to-back long sessions away from an outlet: a spare battery swap resets the clock in seconds, where a built-in cell means waiting for a charger no matter how large the capacity is.

The cooling ceiling is where "versatility" really shows up

X2 Mini Pro ships in standard and liquid-cooled editions, with the liquid-cooled version built to connect to the optional Frost Bay unit for extended high-wattage sessions, the same upgrade path available on APEX. ONEXPLAYER 3 doesn't currently offer a liquid-cooled option. For someone planning to dock the device at a desk for extended sessions and push sustained wattage higher over time, that upgrade path is a real point in X2 Mini Pro's favor.

Where ONEXPLAYER 3 pulls ahead

ONEXPLAYER 3's detachable controller pairs wirelessly and turns its central touchpad into a Windows trackpad once removed, letting the same piece function as both a gamepad and a productivity input device. Combined with its wider 8W-35W TDP range and platform-wide 180 TOPS of AI compute, ONEXPLAYER 3 leans further into being a single device that covers gaming, light AI work, and basic productivity without external accessories.

Making the actual call

If sustained desk sessions and a future cooling upgrade matter, X2 Mini Pro's liquid-cooling path and swappable battery make it the more flexible long-term choice. If the priority is one cohesive device that handles gaming, quick productivity tasks, and light AI work without planning around accessories or charging cycles, ONEXPLAYER 3's built-in feature set and wider TDP range cover more ground out of the box.

Conclusion

Same screen, same size, genuinely different devices underneath. The right pick depends on whether flexibility should live in the cooling system and battery, or in how much a single chassis can do without added parts.
