Impressive performance with Ryzen 7 H255
The AMD Ryzen 7 H255 processor provides high computing power, with performance surpassing the Ryzen 7 8745HS, 7840HS, and 6800H models. Eight cores and sixteen threads, clocked up to 4.9 GHz and 16 MB cache, guarantee smooth operation of demanding applications and multitasking without performance drops. The chip is manufactured with TSMC's 4 nm lithography and, with a TDP of 54 Watts, the computer offers stable operation even under heavy load.
Integrated graphics with the power of a dedicated card
The powerful AMD Radeon 780M chip provides smooth operation for games and graphics programs, offering performance comparable to dedicated GPU cards. The GPU clock frequency is 2600 MHz and the RDNA 3 architecture used guarantees high frame rates – achieving up to 182 FPS in e-sports games and 127 FPS in productions with more advanced graphics. The integrated chip also excels in video editing, 3D design, and high-definition multimedia, making the K12 a versatile computer for work and entertainment.
8K Image on Four Screens
The device supports up to four simultaneous displays with resolutions up to 8K, offering an exceptional visual experience and a large workspace. It features ports such as USB 4.0, USB-C, DisplayPort 1.4, and HDMI 2.1, allowing you to connect a variety of devices—from monitors and graphic tablets to TVs and projectors. It is ideal for creators, analysts, and professionals who need a powerful mini PC for multi-display work and top-quality image editing.
Everything you need for work and entertainment
Create a fully functional workstation for work, gaming, and multimedia. You will have at your disposal 2 USB-C ports, 5 USB-A ports, HDMI 2.1, DisplayPort, 2 LAN 2.5G ports, a CTIA 3.5 mm audio jack, and an OCuLink port (PCIe Gen4 x4) for connecting an external graphics card. This equipment ensures full compatibility with modern devices and guarantees comfortable use in the office, at home, or in the studio.
Support for External Graphics Cards
The OCuLink port allows you to connect an external graphics card, significantly increasing the computer's capabilities in gaming, rendering, and graphic tasks. Such a solution enables you to achieve performance comparable to a full-sized PC while maintaining the compact size of the device. Please note, however, that the OCuLink port does not support hot-plug functionality, so connecting or disconnecting the card should be done with the computer turned off.
Stable connection in every situation
Equipped with 2 Ethernet 2.5G ports, which provide fast and stable data transfer – up to 2500 MB/s. Such a solution guarantees reliability in bandwidth-intensive applications – from office tasks to large file transfers, media servers, or surveillance systems. The computer maintains stable transmission speed and high responsiveness, ensuring smooth operation under all conditions. Using Wi-Fi 6E + Bluetooth 5.2 technology, the GMKtec K12 offers fast and stable connections in all situations. The Wi-Fi standard provides speeds of up to 2,500 Mbps, 37% higher than Wi-Fi 6, which translates to lightning-fast data transfer and low latency for online gaming.
Easy memory and disk expansion
The design of the GMKtec K12 has been developed for upgrade simplicity and maximum flexibility. With easy access to the components, you can expand your computer’s capabilities within minutes by installing up to three M.2 2280 PCIe 4.0 SSDs with a total capacity of up to 24TB (maximum 8TB per slot). In addition, two DDR5 5600 MHz SO-DIMM slots support up to 128GB of RAM (maximum 64GB per slot), allowing you to customize your configuration for the most demanding applications – from working with large files to advanced graphics and computing projects.
Advanced Solutions
The heat dissipation system combines two fans with a copper base to ensure stable operation for up to 72 hours under a 70 W TDP load. The convection airflow design increases cooling performance by up to 200% compared to classic PC Towers, while maintaining a chassis that is just 1/50th of their size. The intelligent system fans and carefully distributed airflow maintain optimal component temperatures, while the rear RGB lighting adds a modern, impressive touch.
Depending on the task at hand, the GMKtec K12 allows you to seamlessly switch between three operating modes, offering the perfect balance between quietness, temperature, and performance. In Quiet mode (35-40 W TDP), the computer operates almost silently, Balanced mode (54-60 W TDP) provides stable power for everyday tasks, and Performance mode (65-70 W TDP) fully utilizes the processor's capabilities for gaming and demanding system applications.
