This AMD-based handheld computer-sized desktop is upgradable

China-based PC manufacturer Trimble has begun selling its T.Book MN45 ultra-compact PC based on the AMD Ryzen 5 4500U accelerated processing unit (APU), which can be placed in the palm of your hand. Unlike most UCFF systems, T.Book MN45 can be upgraded when you need memory, storage, or a faster network connection.

Historically, ultra-compact PCs have three major limitations: reduced performance, fixed configuration, and lack of upgradeability. Modern CPUs have good enough performance for most workloads, so UCFF PC can be used to run most popular applications. The fixed configuration is an inseparable feature of pre-built PCs, but this configuration is easier to upgrade than most.

Trimble’s T.Book MN45 measures 13.3 × 13.3 × 5 cm and can be upgraded at home. The PC is based on AMD’s Ryzen 5 4500U APU, with 6 Zen 2 cores clocked at 2.30 GHz – 4.0 GHz and AMD’s Radeon RX Vega 6 GPU (with 384 stream processors), which is soldered and cannot be changed. But the system has two slots for two DDR4-3200 SO-DIMM memory modules (supports up to 64GB), one M.2 slot for NVMe SSD, and one 2.5-inch tray for SATA SSD or HDD shelf.

The system has many relatively large openings to ensure heat dissipation. In addition, in order to ensure stable performance under high load, T.Book MN45 is equipped with a relatively large radiator with three heat pipes and a fan.

In terms of connectivity, Trimble’s T.Book MN45 has a Wi-Fi 6 + Bluetooth 5.0 adapter, two GbE ports (which are important for corporate customers), and three display outputs (one DisplayPort, one HDMI, and one USB- C, all support 4Kp60 resolution), four USB 3.0 Type-A connectors and a 3.5 mm audio port for headphones. In order to make the device more compact and ready to use, it is equipped with a 65W GaN power adapter.
