📐 Design and construction quality
The G11's chassis is made of reinforced polycarbonate with a dark matte finish that hides fingerprints well. Despite being plastic, the structure feels solid and creak-free.
Its compact dimensions (just over 12 cm per side) allow it to be placed in any corner of the desk or hidden behind the monitor using the included VESA mount.
The port layout is smart: placing everyday connections (10 Gbps fast USB, audio jack and USB-C) on the front and permanent cables (network, power and HDMI cables) on the back.
📺 Screen and multimedia experience
The device supports up to 3 simultaneous displays in 4K resolution at 60 Hz by combining its two HDMI 2.0 ports and the front USB-C video output.
In multimedia playback tests, the Vega 8 iGPU smoothly handles 4K streaming content (YouTube, Netflix, Prime Video). However, it's important to note that this chip lacks hardware decoding for the AV1 codec, so in modern broadcasts that use this format, the CPU will handle some of the processing.
The 3.5 mm audio jack provides a clean signal, without ground loop interference or background electrical noise.
⚡ Performance and Software
In everyday use (intensive web browsing with dozens of tabs, video playback, editing documents in Office and remote management), the GMKtec Nucbox G11 moves with total agility.
Its factory configuration with 16 GB of RAM in Dual Channel makes the difference compared to other budget mini PCs that include only one memory module.
The 256GB NVMe storage offers read speeds of around 2100 MB/s and write speeds of around 1200 MB/s, far superior to any traditional SATA drive.
In terms of software, it comes with Windows 11 Pro pre-installed, free of bloatware or unwanted software. However, where this machine truly shines is under Linux environments (Ubuntu, Debian, Proxmox VE, OpenWrt), where all drivers (2.5G network cards, Wi-Fi 6E, and graphics chip) are recognized natively and 100%.
🔋 Energy consumption, temperature and noise
The cooling system consists of an aluminum heat sink block assisted by a double copper heat pipe and a turbine-type fan.
-
Power consumption: In idle mode , consumption is around 7W-9W. Under maximum CPU and GPU load, total power consumption is around 28W-32W, making it an extremely efficient device for 24-hour operation without significantly impacting your electricity bill.
-
Thermals: In prolonged synthetic load tests, the CPU reaches maximum peaks of 68°C - 72°C, staying well away from the processor's thermal limit.
-
Noise: During light tasks, it is virtually inaudible. At maximum load, the fan noise stabilizes at around 35 dB, manifesting as a soft, inconspicuous hum.
🔌 Connectivity and extras
Connectivity is the device's strongest point. The inclusion of two 2.5 Gbps Ethernet ports (2.5GbE) gives it a significant competitive advantage, allowing for load balancing, VLAN segregation, or even transforming the Mini PC into an advanced router/firewall using pfSense or OPNsense.
In the wireless section, the integrated card manages Wi-Fi 6E and Bluetooth 5.2 bands, offering stable coverage and high download speeds without cables.
⚠️ USB-C limitations notice: The front USB-C port supports data transfer and DisplayPort video output, but does not support Power Delivery (PD). You cannot power a portable monitor using a single USB-C cable or charge the Mini PC through this port.
🛠️ Expansion and Upgrades
