GMKtec K9 Mini PC Review: Versatile Performance

The GMKtec K9 mini PC is perfect for those wanting desktop power in a portable design. Despite its small size, it offers excellent processing and graphics capabilities.

This mini PC is ideal for creative tasks like video editing, photography, intensive office applications, and even gaming. Its expandability stands out, with the ability to boost internal storage and RAM far beyond most competitors.



One notable feature is its expandability. It has dual LAN ports and a USB4 port, perfect for adding an eGPU or extra storage. However, it faces competition from the GMKtec K8, which features the AMD Ryzen 7 8845HS and Radeon 780M. The K9, on the other hand, is powered by the Intel Core Ultra 5 125H CPU and Intel Arc Graphics.

The K9’s build quality is decent, with a silver-coated plastic finish that feels a bit cheap. However, it does have large cooling grates and nice button detailing. Inside, it offers dual M.2 slots and dual-channel RAM for easy upgrades. The base model comes with 1TB storage and 32GB RAM, but you can upgrade to 4TB SSD and 96GB RAM.

Upgrading the K9 involves removing the top plate and fan plate, which requires some effort. Once open, it’s easy to add or replace components.

The Intel Ultra 5 125H processor ensures impressive everyday performance. Office tasks run smoothly, and creative software like Photoshop and Da Vinci Resolve perform well. However, like most mini PCs, the K9 struggles a bit with gaming and doesn’t match the graphics power of full desktop PCs.

When choosing between the K9 and K8, it boils down to Intel vs. AMD preferences. The K8 slightly outperforms in graphics, while the K9 excels in processing speed. Both are powerful and capable, making either a great choice depending on your needs. In summary, the GMKtec K9 is a powerful, expandable, and versatile mini PC, making it a strong contender in the market.

GMKTEC NUCBOX K9 Review: Design

The GMKtec NUCBOX K9 shares the sleek aesthetics of the K8 but has similar design drawbacks. While visually appealing, its metallic-finished plastic casing feels less premium than expected for its price range. The overall look is attractive but slightly cheaper compared to some competitors. The main difference between the K9 and K8 is the switch from an AMD to an Intel chipset.

Accessing the inner hardware is straightforward. You can pry off the top plate without tools, revealing a small cooling fan secured by four screws. Removing this plate requires some effort, and you’ll need to unplug the fan’s mainboard connector to reach the internal components.

Inside, the layout is spacious and neat, allowing good airflow through two large vents. On one side, you’ll find two PCIe 4.0 M.2 slots and SODIMM DDR5 memory slots. Our review unit featured two 16GB Crucial DDR5 5600 modules, totaling 32GB and upgradeable to 96GB—one of the highest capacities among mini PCs. The Dual M.2 slots, one occupied by a 1TB M.2 2280 PCIe 4.0 SSD, are expandable to two 2TB modules. Beneath the RAM is the WiFi 6 (2.4GHz/5.0GHz) and Bluetooth 5.2 card, allowing future upgrades.

The K9 features a standard array of ports. The front includes a USB4 port, two USB 3.2 Gen 2 ports, and a 3.5mm audio jack. The rear has a DisplayPort 1.4 (4K@144Hz), HDMI 2.0 (4K@60Hz), two USB 3.2 Gen 2 (10Gbps) ports, two 2.5Gbps Ethernet ports, a Kensington lock, and a DC power socket.

Overall, the design is neat but doesn’t fully showcase the chipset’s power, with only one USB4 port and a somewhat cumbersome upgrade process.

GMKTEC NUCBOX K9 Review: Components

The GMKtec K9 Mini PC is ideal for power users who need a compact and expandable computing solution. It features the latest Intel Core Ultra 5 125H processor with 14 cores and 18 threads, reaching speeds up to 4.50 GHz.

This mini PC also includes Intel Arc Graphics 112EU iGPU, based on the Meteor Lake GT1 graphics processor. It supports DirectX 12, making it perfect for demanding tasks like video and image editing. Additionally, Intel’s AI Boost technology enhances performance by optimizing the use of both CPU and GPU based on the workload. This technology supports OpenVINO, Windows ML, DirectML, and ONNX RT.

The K9 comes with 32GB of DDR5 dual-channel RAM running at 5600MHz, expandable to 96GB with new 48GB RAM modules. It includes a 1TB M.2 2280 PCIe 4.0 SSD, with dual slots allowing up to 4TB of internal storage.

Connectivity options are extensive. The front features a USB4 port, Thunderbolt 4 compatible, with transfer speeds up to 40 Gbps. Although positioned on the front, it remains functional. Additionally, there are two USB 3.2 Gen 2 ports on the front and two more on the back.

Networking is strong with dual 2.5Gbps LAN ports, WiFi 6, and Bluetooth 5.2. You can connect up to three displays via the USB4 port (up to 8K@60Hz), DisplayPort, and HDMI options. The placement of the USB4 port on the front is a bit unusual, but it works well.
