GMKTec NucBox K8’s Technical Specifications

The GMKTec NucBox K8 is powered by the AMD Ryzen 7 8845HS, an 8-core, 16-thread processor with a base clock of 3.8 GHz and a boost clock up to 5.1 GHz. The processor is paired with integrated Radeon 780M graphics, which delivers robust performance for both productivity and light gaming tasks. The mini PC supports up to 32GB of DDR5 RAM at 5600 MT/s and includes a 1TB NVMe PCI-E Gen 4.0 SSD, ensuring quick data access and smooth multitasking.

GMKTec NucBox K8 Specifications

In terms of connectivity, the NucBox K8 is equipped with Wi-Fi 6E and Bluetooth 5.2 for seamless wireless communication. It also features dual 2.5GB Ethernet ports, providing high-speed wired network options. The I/O ports include one USB 4.0 Type-C port, four USB Type-A 3.2 ports, a DisplayPort, and an HDMI port, supporting up to 4K@60Hz display output.

Build and Design

The GMKTec NucBox K8 has a compact plastic chassis, which might not feel as premium as metal but offers sufficient durability and heat dissipation thanks to its dual-fan cooling system. The device includes a VESA mounting bracket, allowing it to be easily attached to the back of a monitor or TV, making it a space-saving solution for various setups. The power supply is a non-brand HuntKey unit, delivering up to 120W, which is adequate for the mini PC’s power requirements.

NucBox K8 RAM & Storage

Upgrading the NucBox K8 is straightforward, with access to two PCI-E NVMe slots for additional storage. The included Crucial brand DDR5 RAM ensures reliable performance, while the advanced BIOS settings allow users to optimize the mini PC’s power and performance settings, including options for auto power-on and memory configuration.

Benchmark Results and Performance

In benchmark tests, the GMKTec NucBox K8 shows performance on par with the previous generation Ryzen 7840HS. In Geekbench 6, it scored nearly 2500 in single-core and close to 13,000 in multi-core tests, which are impressive results for a mini PC. The Radeon 780M graphics scored around 2600 in 3DMark’s Time Spy, indicating solid graphical capabilities for integrated graphics.

NucBox K8 CPU Specifications

When compared to similar products, the NucBox K8 holds its own, particularly in CPU-intensive tasks. However, its performance is nearly identical to its predecessor, the Ryzen 7840HS, suggesting that the primary improvement in the 8845HS is the inclusion of the new MPU for AI tasks. This makes the NucBox K8 a strong contender in its category but not a significant leap forward from the last generation.

Real-World Performance

In real-world usage, the NucBox K8 excels in various scenarios. It handles 4K video playback smoothly, making it a great choice for media consumption. During gaming tests, titles like “The Last of Us Part I” and “The Witcher 3” performed well at lower settings, maintaining playable frame rates. While not suitable for high-end gaming, it performs admirably in less demanding games and older titles.

The NucBox K8’s integrated Radeon 780M graphics also provide decent emulation performance, running retro games smoothly. The SSD’s read and write speeds are impressive, enhancing the overall system responsiveness and reducing load times in applications and games.

Uses and Benefits of a Mini PC

Mini PCs like the NucBox K8 offer numerous benefits for both home and office environments. Their compact size and VESA mount compatibility make them ideal for space-constrained areas. These devices consume less power than traditional desktop PCs, making them more energy-efficient and environmentally friendly. Additionally, they are great for travelers, offering portable computing power that can be easily carried and connected to external displays.
