GMK NucBox K1 vs. Chuwi LarkBox Mini PC Review: Two Birds of a Feather

Unreliable. On paper, the GMK mini PC has the better processor with more RAM, more storage, and faster Wi-Fi than the Chuwi equivalent. Unfortunately, our pre-production unit doesn't always work as intended.

Not to be outdone by the Chuwi LarkBox, the GMK NucBox K1 is yet another ultra-small mini PC designed to fit just about anywhere. It's also notable for being one of the very few PCs shipping with a Gemini Lake Celeron J4125 CPU processor alongside a tiny internal fan to keep it all cool.

The manufacturer is aiming for a price of $209 USD while early backers can get one for as low as $159. Our pre-production test unit should mostly represent what backers will see once the NucBox K1 goes into mass production later this year.

Connectivity

Port options are the same as on the Chuwi LarkBox. Unfortunately, the single USB-C port is used only for power which precludes the use of USB-C accessories. Attempting to expand this port via docking stations will not work.

SD Card Reader

Transfer rates from the integrated MicroSD card are similar to the LarkBox, but real-world performance can be slower depending on the sizes of the files being transferred. A fully inserted MicroSD card sits flush against the edge and can be difficult to eject.

Communication

While the integrated Intel 7265 is capable of transfer rates of up to 867 Mbps, real-world performance is much slower when connected to our Netgear RAX200 test router. We experienced constant random disconnects on our unit. Bluetooth 4.2 otherwise works as intended.

Accessories and Warranty

There are no extras in the box other than the AC adapter and paperwork. Claiming warranty will also be tricky as it may involve overseas shipping for many buyers.

Performance

Processor

The quad-core Celeron J4125 is clocked 200 MHz faster than the Celeron J4115 in the LarkBox (2.0 - 2.7 GHz vs. 1.8 GHz - 2.5 GHz). In practice, benchmarks rank our J4125 slightly slower likely due to the poor implementation by GMK. Overall performance is not all that different from the older Celeron N4100.

See our dedicated page on the Celeron J4125 for more technical information and benchmark comparisons.

Storage Devices

Our unit comes with a 128 GB HIKVISION C100 M.2 SATA III SSD. The drive is removable and can be replaced with another M.2 2242 SSD if desired. Transfer rates are faster than many embedded solutions like the ones in the Chuwi LarkBox or GBox, but copy rates are still very slow.

GPU Performance

Graphics performance is consistently slower than the Chuwi LarkBox even though the NucBox is supposed to be the faster machine. This thankfully has no practical implications, but it shows that just because one model has a better processor on paper doesn't necessarily mean that it's the faster system in practice. Raw GPU performance is still where we expect it to be relative to other laptops with the same UHD Graphics 600 option.

Emissions

System Noise

The fan is constantly pulsing between silent and 46.8 dB(A) with no other speed in between. You can be browsing the web or emailing and the fan will pulse to its maximum speed seemingly for no reason. It's not annoying if in a living room HTPC environment, but it's definitely noticeable and undesirable if in a smaller office or conference room.

Temperature

Surface temperatures are never uncomfortably warm no matter the load. However, be sure to not block any of the ventilation grilles along the top or rear since there is a fan inside.

Stress Test

When running Prime95, the CPU would boost to 2.5 GHz for the first couple of seconds before stabilizing at the 1.9 GHz to 2.2 GHz range. Core temperature plateaus at a worrying 101 C to 102 C which GMK says will be addressed in the final retail model.

Power Consumption

Idling on desktop consumes between 3 W to 4 W to be about 1 W more than the LarkBox. We're able to record a maximum draw of 22.7 W from the small (~5.5 x 5.5 x 2.8 cm) 24 W AC adapter when running extreme loads. However, this maximum only lasts for a few seconds as shown by our graphs below.

Pros

+ integrated HDMI, MicroSD reader, and 2x USB-A ports
+ impressive storage and RAM for such a small design
+ expandable M.2 2242 SSD
+ attractive chassis design
+ 2x2 Wi-Fi 5 connectivity
+ relatively inexpensive

Cons

- dropped frames during 4K60 playback
- unreliable performance and WLAN
- USB-C port is for power only
- slow CPU performance
- fan pulses frequently

Verdict

In review: GMK NucBox K1. Test unit provided by GMK
In review: GMK NucBox K1. Test unit provided by GMK

Based on our time with the pre-production unit, the NucBox K1 is not ready for a wider release. The Wi-Fi constantly drops, the fan pulses frequently, the MicroSD reader will sometimes not recognize the card, USB devices turn on and off inexplicably, and system performance is jittery even when compared to the competing Chuwi LarkBox. The price, design, and overall concept are attractive, but you'd be better off spending a bit more on a larger and more reliable mini PC or even a last generation Intel NUC.

We're hopeful that GMK will fix all of these issues on final retail units. If you still plan on backing the project, then we definitely recommend stress testing your system and making sure all the ports and radios are working as intended.

Allen Ngo - US Editor in Chief
After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
