MINIX’s ER939-AI Pro is a compact workstation built around AMD’s Ryzen AI Max+ 395 processor. The 2-liter desktop pairs 128GB of LPDDR5X memory with dual 10GbE networking, targeting professional workloads that typically require much larger hardware.
The ER939-AI Pro follows the earlier ER939-AI and adds a significant networking upgrade. The previous model featured a 2.5GbE port, while the new version moves to dual 10GbE LAN connections for faster data transfers and storage access.
AMD’s Ryzen AI Max+ 395 features 16 Zen 5 CPU cores and 32 threads with boost clocks reaching up to 5.1GHz. Integrated Radeon 8060S graphics are part of the package, alongside an NPU rated for up to 50 TOPS. AMD lists total platform AI performance at up to 126 TOPS.
The workstation ships with 128GB of LPDDR5X-8000 memory as standard. Most mini PCs currently ship with 32GB or 64GB memory, making the ER939-AI Pro one of the highest-capacity compact desktops currently available. The memory is soldered to the motherboard and cannot be upgraded.
A 2TB PCIe 4.0 NVMe SSD comes pre-installed. MINIX launch the machine with two M.2 2280 PCIe 4.0 x4 slots, allowing users to add more storage if required.
HDMI 2.1 FRL, DisplayPort 1.4, and two USB4 ports provide support for up to four displays at the same time. Each connection supports resolutions up to 8K at 60Hz.
Dual 10GbE connectivity is uncommon in the mini PC segment. The configuration is aimed at environments that rely on high-speed network storage, large media files, engineering projects, and other bandwidth-intensive workloads.
Wi-Fi 7 and Bluetooth 5.4 are available for wireless connectivity.
The front panel contains a USB4 port, two USB 3.2 Gen 2 Type-A ports, an SD card reader, and a 3.5mm audio jack. Rear connectivity consists of another USB4 port, USB 3.2 Gen 2 Type-A, USB 2.0, HDMI 2.1 FRL, DisplayPort 1.4, dual 10GbE LAN ports, and an additional audio connector.
The chassis measures 215.5 × 180.8 × 70.6 mm and weighs approximately 1.6 kg. Windows 11 Pro comes pre-installed.
MINIX has listed the ER939-AI Pro at 698,000 yen in Japan, which converts to roughly $4,356. Shipments are scheduled to begin in late June 2026.
