The MSI Cubi NUC AI Plus 3MG follows a Micro-ATX form factor while maintaining a notably compact footprint, measuring 119.6 mm wide, 115.2 mm deep, and just 37.5 mm tall, resulting in a total volume of 516.672 cm³. Storage is handled by a 1000GB NVMe SSD, offering fast read and write access through the NVMe interface. Despite its small dimensions, the chassis accommodates these components within a well-defined physical envelope suited to space-constrained deployments.
The processor operates within a 25W TDP envelope, with base clock speeds distributed across three core clusters running at 4 x 2.1 GHz, 8 x 1.6 GHz, and 4 x 1.6 GHz respectively, and a turbo clock speed reaching up to 4.9 GHz via Turbo Boost version 2. It supports 16 threads and includes an 18 MB L3 cache, alongside integrated graphics and full 64-bit instruction support. The maximum rated CPU temperature is 100 °C, providing a clear thermal ceiling for the chip under sustained load.
The integrated graphics solution runs at a turbo frequency of 2500 MHz and connects via PCIe 5, providing a modern, high-bandwidth interface. It supports DirectX 12 Ultimate along with OpenGL 4.6 and OpenCL 3, covering a broad range of graphics and compute workloads. The GPU can drive up to four displays simultaneously, making it a capable option for multi-monitor setups within this compact Mini PC form factor.
The MSI Cubi NUC AI Plus 3MG comes equipped with 32GB of DDR5 RAM, reflecting the use of the fifth generation of DDR memory technology, which operates at higher frequencies and with improved efficiency compared to its predecessors. This memory configuration provides a solid foundation for handling multitasking and data-intensive applications within the system's compact chassis.
Wireless connectivity covers Wi-Fi 4, 5, 6, 6E, and Wi-Fi 7 (802.11be), alongside built-in Bluetooth 5.4. On the wired side, two RJ45 ports provide dual Ethernet connectivity, while the USB layout includes one USB 2.0 port, one USB 3.2 Gen 2 Type-A, one USB 3.2 Gen 2 Type-C, and two USB 4 40Gbps ports — though there are no USB 3.2 Gen 1, Gen 2x2, or USB 4 20Gbps ports present. High-speed device connectivity is further reinforced by two Thunderbolt 4 ports, with no Thunderbolt 3 ports included. Display outputs consist of two HDMI 2.1 ports and two DisplayPort outputs, while a 3.5 mm headset jack handles audio; there is no VGA connector and no S/PDIF output.
The system supports up to 128GB of RAM across two memory channels, with a maximum RAM speed of 8533 MHz, though it does not include an external memory slot or use flash storage. The processor is of the laptop type and employs big.LITTLE technology for its core configuration, with supported instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. Security is addressed through NX bit support, and the unit ships with a one-year warranty period.
