The GMKtec NucBox M5 Ultra is a compact desktop computer that offers a range of features for users looking for performance and flexibility. It is powered by an eight-core AMD Ryzen 7 7730U processor, which was released in 2023. This CPU is essentially a rebranded version of the Ryzen 7 5825U from 2022, which itself is a slightly updated version of the 2021 Ryzen 7 5800U. The NucBox M5 Ultra starts at $330 for a basic setup, though bulk purchases of five units can bring the price down to as low as $280 per unit. The system includes two DDR4-3200 SODIMM slots, allowing up to 64 GB of memory, and two M.2 2280 slots for storage. However, the Ryzen 7 7730U processor limits the M.2 slots to PCIe 3.0 speeds, as it only provides 16 usable lanes and lacks support for the newer PCIe 4.0 standard. The Ryzen 7 7730U is part of AMD's Cezanne processor series, launched in early 2022, and is closely related to the Ryzen 7 5825U, which had slightly higher clock speeds than the earlier Ryzen 7 5800U from 2021. Connectivity is a strong point for the NucBox M5 Ultra. It includes two 2.5 Gigabit Ethernet ports, Wi-Fi 6E, and Bluetooth 5.2 for wireless communication. Additional ports include a high-speed 10 Gbps USB port, two USB 3.2 Gen 2 Type-A ports, and two USB 2.0 ports. For display output, the system supports up to three monitors simultaneously using HDMI 2.0, DisplayPort, and USB-C connections. The unit is powered by a 65W power supply connected via a Type-C port. Despite the need to purchase separate DDR4 laptop RAM and SSDs, which may be seen as an inconvenience, the NucBox M5 Ultra is praised for its robust connectivity, performance, and customizability as of 2026. It caters to users who want to build a system tailored to their specific needs, offering a balance of power and flexibility in a compact form factor.
