Let’s delve into the specifications of the Nucbox K6, a powerhouse Mini PC that promises exceptional performance. At its core lies the AMD Ryzen 7 7848 CHS processor, featuring eight Zen 4 cores and 16 threads. With a base clock speed of 3.8 GHz and a boost clock up to 5.1 GHz, this CPU ensures smooth and responsive computing across a variety of tasks.
The built-in Radeon 780M iGPU, based on RDNA 3 architecture and clocked at up to 2700 MHz with 12 compute units, delivers stunning graphics performance for gaming, content creation, and multimedia tasks. The Nucbox K6 supports up to 64 GB of DDR5 SODIMM RAM, offering lightning-fast memory speeds of up to 5600 MHz.
Storage options are abundant with two M.2 NVMe slots, allowing for blazing-fast data access and storage expansion. Connectivity is top-notch with Wi-Fi 6 and Bluetooth 5.2, ensuring seamless wireless connectivity.
Out of the box, the K6 runs Windows 11 Pro, providing a secure and feature-rich operating environment for users. Accessing the internals of the device is a breeze, thanks to the easily removable cover. Underneath, a single fan setup efficiently cools the NVMe SSDs and RAM modules, ensuring optimal performance under heavy workloads.
Before delving into real-world testing, it’s essential to assess the Thermal Design Power (TDP) of the Nucbox K6 out of the box. Using a combination of applications like Core Temp, CPU-Z, and GPU-Z, we can gauge the power consumption across the CPU and GPU.
Upon running stress tests, the TDP peaked at 54 Watts, indicating that the cooling system is effectively managing the thermal output. However, for users seeking even more performance, the X86 Tuning Utility offers customization options. By switching to Extreme mode, we observed a TDP increase to 70 Watts, pushing the system to its limits while maintaining manageable temperatures.
Moving on to benchmarks, the K6 showcases impressive performance across various metrics. In Geekbench 6, the single-core score reached 2,465, while the multi-core score hit 12,774, aligning with expectations for this hardware configuration. Despite the increased TDP in Extreme mode, temperatures remained within acceptable limits during these tests.
