Mouse Computer has introduced the X2, a compact Windows 11 laptop that offers a choice of AMD processors in a lightweight 981g chassis. The Japanese manufacturer has fitted the machine with a 12.2-inch display while retaining upgrade options for users who want more memory later.
Measuring 277.1mm wide, 210.2mm deep, and 19mm thick, the X2 targets users who want a highly portable computer without moving entirely into lower-powered hardware. Its small footprint also makes it notably lighter than many mainstream 13-inch and 14-inch laptops.
Three AMD processor options target different performance levels
The X2 is available with three AMD processor configurations, giving customers a choice between more affordable hardware and newer Ryzen AI chips. The entry-level Ryzen 5 216 uses six cores, combining two Zen 4 cores with four smaller Zen 4c cores. Early benchmark comparisons suggest its performance is broadly similar to AMD’s Ryzen 5 8540U.
The next option is the Ryzen AI 5 340, part of AMD’s Krackan Point family. It also features six cores and is positioned as a stronger option for users who need additional processing power in a compact machine. Early multicore benchmark results place the processor around Intel’s Core Ultra 7 165H and slightly ahead of the Core Ultra 5 325 in some comparisons.
At the top of the range is the Ryzen AI 7 350, which features eight cores split between four Zen 5 and four Zen 5c cores. Preliminary benchmark comparisons suggest its multi-threaded and synthetic performance can approach Intel’s Core Ultra 9 185H, though real-world performance will depend on the workload and system configuration.
The X2’s 12.2-inch display has a 1920 by 1200 resolution and is reported to cover the full sRGB colour gamut. The panel is mounted on a 180-degree hinge, allowing it to be folded completely flat when needed. This could make the laptop useful for working collaboratively or sharing content across a desk.
Storage comes from a 500GB NVMe SSD, while the laptop includes a 60Wh battery. Mouse claims battery life of approximately 12.5 hours during video playback and around 25 hours when idle, based on measurements using the JEITA 3.0 testing standard. Actual endurance will likely vary depending on brightness, applications, connectivity, and processor configuration.
Extensive connectivity in a compact chassis
Despite its small size, the X2 includes a relatively broad selection of ports and wireless connectivity. The laptop supports Gigabit Ethernet for wired networking, alongside Wi-Fi 7 and Bluetooth 5. It also includes USB Type-A ports, an HDMI output, and a microSD card slot for additional storage.
The system includes a 2-megapixel webcam with a physical privacy shutter. The camera also supports Windows Hello, allowing compatible users to sign in to Windows using facial recognition. Windows 11 Home is installed as standard across the range.
Mouse has also retained an upgrade path for memory. The laptop ships with 16GB of RAM in a single-channel configuration, while one SODIMM slot remains free. This allows users to add another 16GB DDR5-5600 module and increase the system’s memory to 32GB.
The upgradeable design is notable given the X2’s compact dimensions. Many thin and light laptops use soldered memory, leaving users with no practical way to increase RAM after purchase. Mouse’s decision to retain an empty SODIMM slot gives buyers more flexibility, although adding a second module would require an additional purchase.
The company is offering the X2 in three finishes: Cosmo Blue, Frost Gold and Pearl White. The combination of a sub-1kg weight, upgradeable memory and a range of AMD processors gives the machine a specification that is more flexible than its small dimensions might suggest.
X2 remains exclusive to Japan at launch
Mouse has confirmed pricing for the higher-powered configurations, although availability is currently restricted to Japan. The Ryzen AI 5 version with 16GB of memory and a 500GB SSD is priced at ¥239,800, equivalent to about US$1,545. The Ryzen AI 7 model with the same memory and storage configuration costs ¥259,000, or approximately US$1,670.
Sales are scheduled to begin sequentially from October through Mouse Computer’s Japanese online store. The company has not indicated that the X2 will be officially sold in other international markets, leaving customers outside Japan without a local retail option for now.
For international buyers, importing the laptop would therefore be the main route to obtaining one. That could add shipping costs, taxes and potential warranty complications to the Japanese retail price. Keyboard layout and regional support could also be considerations for buyers importing the machine.
Memory upgrade cost is another factor. A compatible 16GB DDR5-5600 SODIMM module is available separately, although pricing can vary considerably by supplier. Adding a module would also change the memory configuration from single-channel to dual-channel, potentially improving performance in workloads that benefit from higher memory bandwidth.
For now, the X2 remains a Japan-focused compact laptop rather than a broadly available international model. Its combination of a 981g chassis, 12.2-inch 1920 by 1200 display, AMD Ryzen AI processors, Wi-Fi 7 and user-accessible memory expansion nevertheless makes it an unusual addition to the small-laptop market.
