GMKtec is back with another exciting mini PC launch! The brand has officially introduced the new GMKtec NucBox M3S, a compact desktop computer powered by Intel’s next-generation Core 3 304 processor, featuring Intel 18A technology, dedicated AI acceleration, ultra-fast LPDDR5 memory, USB4 connectivity, and support for three 4K displays. Even better, existing GMKtec customers can take advantage of an exclusive $15 discount with the promotional code M3SFB15! Designed for modern workspaces, home offices, entertainment, and everyday productivity, the GMKtec M3S combines a space-saving design with impressive connectivity and power-efficient computing. With an introductory price starting at just $389.99, reduced from the listed $519.99, this new arrival deserves attention from mini PC enthusiasts.
Intel Core 3 304: Next-Generation Performance Meets Intel 18A Efficiency
The biggest highlight of the GMKtec NucBox M3S is undoubtedly its Intel Core 3 304 processor, built on Intel’s advanced 18A manufacturing process and based on the new Wildcat Lake architecture. The chip features five cores and five threads, combining one Performance-core with four Low Power Efficient-cores, a maximum turbo frequency of 4.3GHz, and 6MB of Intel Smart Cache. This modern architecture is designed to deliver responsive performance while keeping power consumption under control. Whether you’re browsing with multiple tabs, editing documents, working with spreadsheets, attending video meetings, streaming 4K content, or handling everyday multitasking, the NucBox M3S aims to deliver a smooth and efficient Windows experience.
According to the promotional benchmark graphic citing NanoReview, the Intel Core 3 304 achieves a Geekbench 6 multi-core score of 6,529 points, compared with 6,005 for the AMD Ryzen 5 5500U and 4,826 for the Ryzen 3 7330U. These are reference figures rather than independent CGR test results, but they certainly make the processor an interesting candidate for real-world performance testing. GMKtec also provides three selectable performance profiles: Silent Mode at 15W, Balanced Mode at 20W, and Performance Mode at 25W, allowing users to prioritize quieter operation or additional processing power depending on their workload. A copper heat pipe and active fan cooling system help manage temperatures inside the compact chassis.
Built-In AI Acceleration: Up to 15 TOPS NPU Performance
Artificial intelligence is becoming increasingly relevant in modern computing, and the GMKtec M3S arrives prepared with a dedicated Neural Processing Unit delivering up to 15 TOPS of AI performance. This integrated NPU is designed to accelerate compatible AI workloads more efficiently than relying exclusively on traditional CPU processing. Combined with Intel Graphics, which offers up to 9 TOPS of INT8 GPU compute performance according to GMKtec, the M3S brings dedicated AI hardware to an accessible compact desktop platform. Actual AI application compatibility and performance will depend on software support, but this is certainly an interesting addition for users who want to explore AI-enhanced productivity tools and emerging local AI workloads.
Fast LPDDR5 Memory and Expandable NVMe Storage
The new GMKtec NucBox M3S features 12GB of LPDDR5 memory operating at 5600MT/s, providing the bandwidth needed for everyday productivity and multitasking. The memory is soldered onboard and cannot be upgraded, which is worth considering for users planning more demanding workloads in the future. Storage options include 256GB and 512GB NVMe SSD configurations. GMKtec also provides two M.2 2280 PCIe 4.0 x2-compatible SSD slots, with one occupied by the preinstalled drive, offering additional storage flexibility and a maximum combined capacity of up to 16TB, according to the manufacturer. With Windows 11 Pro preinstalled, the NucBox M3S is ready for a wide variety of professional, educational, and home computing applications.
Triple 4K Displays, USB4 and 2.5GbE: Impressive Connectivity in a Tiny PC
Despite its compact dimensions of just 114 × 106 × 42.5mm and approximately 430g weight, the GMKtec M3S offers a surprisingly comprehensive connectivity package. Its USB4 Type-C interface supports transfer speeds of up to 40Gbps, while two HDMI 2.0 outputs make it possible to connect up to three 4K displays simultaneously at 60Hz when combined with the USB4 video output. This makes the M3S particularly attractive for multitasking setups, home offices, financial dashboards, content monitoring, and productivity environments where additional screen space can make a real difference. The mini PC also includes three USB 3.2 Gen 2 Type-A ports, one USB 2.0 port, a 3.5mm audio connection, and a 2.5GbE Ethernet port for fast wired networking. Wireless connectivity is equally convenient thanks to Wi-Fi 6 and Bluetooth 5.2, making it easy to connect modern peripherals, wireless headphones, and other compatible devices.
Compact Design, Big Possibilities for Everyday Computing
The GMKtec NucBox M3S is designed for anyone who wants a capable desktop computer without the bulk of a traditional tower. Its small footprint makes it easy to place beside a monitor or integrate into a minimalist workspace, while the included VESA mounting option provides additional installation flexibility. From students and remote workers to professionals managing multiple displays, the M3S could be an interesting solution for office productivity, multimedia streaming, digital signage, remote desktop access, programming projects, and general home computing. Its combination of efficient Intel processing, dedicated AI acceleration, fast connectivity, and expandable storage creates an appealing hardware platform, although demanding gaming and heavy professional rendering are not its primary focus.
