A palm-sized gaming handheld now carries an integrated GPU with 40 compute units. One-Netbook Technology announced the ONEXPLAYER X2 Mini Pro on July 21, 2026, pairing an 8.8-inch OLED panel with AMD's Ryzen AI Max+ 388. Attach the external liquid-cooling unit and the power envelope rises to 120W. Pricing starts at 2,499 USD (about 405,000 yen), with shipping planned for August.

Chasing RTX 4060-Class Output with an Integrated GPU

The Ryzen AI Max+ 388 at the core combines an 8-core, 16-thread Zen 5 CPU with RDNA 3.5-generation Radeon 8060S graphics. It carries 40 compute units and a GPU clock reaching 2,900MHz. One-Netbook describes the result as rendering performance comparable to a GeForce RTX 4060 Laptop GPU, achieved without a discrete GPU.

Part of that comes from the shared memory pool used by the CPU, GPU and NPU. Because data does not need to be copied between them, latency drops and a much larger share of memory can be handed to graphics. The same structure matters when running AI models locally on the device.

On that note, a local AI assistant is built in and ready from first boot. It runs fully offline rather than routing through the cloud, aimed at users who would rather keep their data on the machine.

80W on Air, 120W with the Liquid Cooler

What ultimately limits a handheld is how much heat it can shed. The X2 Mini Pro sustains up to 80W on its standard air cooling alone. The cooling fin area measures 47,200 square millimeters, unusually large for an 8.8-inch chassis, which keeps clocks from sagging under prolonged load.

Connecting the external ONEXPLAYER Frost Bay liquid-cooling system raises the ceiling to 120W. Frost Bay uses a CNC-machined housing with RGB lighting and is designed to hold desktop-class power draw while staying quiet. The intended pattern is liquid cooling at the desk, bare handheld on the move.

The lineup splits along the same line. Air-cooled models run 2,499 USD for 48GB memory with 1TB storage, 2,799 USD (about 453,000 yen) for 64GB with 1TB, and 2,999 USD (about 486,000 yen) for 64GB with 2TB. Liquid-cooling-ready models start at 2,579 USD (about 418,000 yen), with the 64GB and 2TB configuration bundling Frost Bay at 3,229 USD (about 523,000 yen).

Three Form Factors and a Swappable Battery

The X2 Mini Pro uses detachable controllers. Attached, it is a handheld; removed, a tablet; add the optional magnetic keyboard and it becomes a laptop. The controllers connect through a dedicated native connector, so there is no wireless pairing step and no added input delay.

The controls themselves were reworked. The sticks use non-contact Hall-effect sensing to limit drift and wear. The triggers are a dual-stage design with physically switchable travel, and Hall-effect sensing reads input to within 0.1mm. Short travel suits shooters, longer travel suits racing titles.

The 85Wh battery snaps on and off, and also supports a direct cable connection. Carrying a spare removes the need to stop and charge. A dedicated dock charges batteries independently and shows status on a built-in LED display.

Storage runs on two paths: an internal M.2 2280 PCIe 4.0 slot plus an external Mini SSD expansion bay. That works both for keeping a large local game library and for isolating AI models on a separate drive.

Key Specifications

The display is an 8.8-inch OLED panel at 1,920 by 1,200 with a 144Hz refresh rate. Memory options are 48GB of LPDDR5x-7464 or 64GB of LPDDR5x-8000, with 1TB or 2TB NVMe M.2 SSD storage. Wireless covers Wi-Fi 7 and Bluetooth 5.4, and the machine includes a USB4 port and a MiniSSD slot.

The chassis measures 313mm wide, 138mm deep and 22mm thick, weighing 799g. That is not light for an 8.8-inch device, but it is reasonable given the swappable battery and the oversized cooling assembly inside.

Summary

The ONEXPLAYER X2 Mini Pro pairs the Ryzen AI Max+ 388 with Radeon 8060S graphics to reach discrete-GPU territory without a discrete GPU. The two-tier power envelope of 80W on air and 120W with liquid cooling, the detachable controllers and battery, and the dual storage paths all point toward performance and expandability rather than minimalism. Starting at 2,499 USD, it costs as much as a capable desktop gaming PC, but for anyone who wants one portable machine for both gaming and creative work, it earns a look. Pre-orders are open through the manufacturer's own store, with shipping planned for August.
