Experience desktop-grade power in an ultra-compact footprint with the GMKtec K12 Mini PC. Powered by the high-performance AMD Ryzen 7 H255 processor and paired with integrated AMD Radeon 780M graphics, this mini PC easily outperforms traditional tower setups while taking up a fraction of desk space. Pre-installed with Windows 11 Pro, equipped with 32 GB of high-speed DDR5 memory, and a 1 TB PCIe 4.0 SSD, the K12 is crafted for demanding professionals, content creators, software developers, and gamers looking for high efficiency without compromise.
Next-Gen AMD Ryzen 7 Power
At the heart of the GMKtec K12 is the 8-core, 16-thread AMD Ryzen 7 H255 processor built on TSMC's 4nm architecture. Reaching clock speeds up to 4.9 GHz with a 16 MB cache, it delivers smooth multitasking and rapid execution for heavy compute workloads. Integrated Radeon 780M graphics based on RDNA 3 architecture deliver discrete-level GPU performance (2600 MHz clock speed), making high-definition video editing, 3D rendering, and smooth e-sports gaming up to 182 FPS a reality.
Quad 8K Display & Dedicated OCuLink Port
Maximize your workflow productivity across multiple monitors. The GMKtec K12 supports up to four simultaneous displays at up to 8K resolution via dual USB4, HDMI 2.1, and DisplayPort 1.4. For graphics enthusiasts requiring desktop-class rendering power, the built-in OCuLink (PCIe Gen4 x4) interface allows seamless connection to an external dedicated graphics card (eGPU).
High-Speed Networking & Massive Expandability
Stay connected with ultra-fast dual 2.5G Ethernet ports alongside Wi-Fi 6E and Bluetooth 5.2. Expansion is remarkably effortless: support for up to 128 GB of DDR5 RAM and up to three M.2 2280 PCIe 4.0 SSD slots allows for an astonishing total storage potential of up to 24 TB.
Custom Cooling & Performance Modes
Featuring a dual-fan copper cooling module, convection airflow keeps the K12 running stably under 70W loads for extended periods. Switch seamlessly between three performance modes (Quiet 35-40W, Balanced 54-60W, Performance 65-70W) depending on your workload while enjoying subtle RGB ambient lighting.
