GMK NucBox M5 mini PC review: AMD Zen 2 is feeling long in the tooth

The NucBox M5 is the latest entry-level mini PC from GMK in contrast to the more expensive NucBox K series. It utilizes older processor options in order to keep costs low.
Our test unit comes configured with the Zen 2 Ryzen 7 5700U CPU, 32 GB of DDR4-3200 RAM, and 1 TB of storage for approximately $470. Barebone SKUs are also available with no RAM or storage starting at $320, but all options otherwise come with the same processor.
Alternatives to the NucBox M4 include other inexpensive mini PCs like the Beelink SER5, BMax B7 Power, or Maxtang MTN-FP750.

Connectivity
Port options are the same as on the NucBox K6 but with two key downgrades. The single USB-C port now lacks USB4 and Thunderbolt support while one of the rear USB-A ports is now 2.0 instead of 3.2.

Maintenance
The top cover pops off to reveal the fan cover underneath and four Phillips screws for easy access to the two DDR4 SODIMM slots, 2x M.2 2280 SSD slots, and WLAN module. Meanwhile, the bottom cover is not removable and so the other side of the motherboard is more difficult to access.
Accessories And Warranty
The retail box includes an HDMI cable and a removable VESA mounting bracket alongside the AC adapter and paperwork. The standard one-year limited manufacturer warranty applies if purchased in the US.
Performance — Zen 2 Ain't Worth It In 2024
Testing Conditions
We set Windows to Performance mode prior to running the benchmarks below. The system comes with no bloatware or manufacturer-specific applications for a clean Windows experience.
Processor
CPU performance is slower than expected. Our Ryzen 7 5700U would run 20 to 25 percent slower than the average laptop in our database equipped with the exact same processor. It still runs laps around any mobile Celeron, Pentium, or Atom solution, but raw performance is still a bit disappointing as we know the Ryzen 7 5700U is capable of much more.
Overall performance is neck-to-neck with the 11th gen Intel Core i7-1165G7 as found on the older 2021 NUC11 series.

Stress Test
When running Prime95 to stress the CPU, clock rates and board power draw would spike to 1.9 GHz and 15 W, respectively. We believe that the processor is capable of higher power envelopes of up to 28 W especially since core temperature is only 55 C under stress, but package power is seemingly limited to 15 W on the NucBox M5 even after double-checking any BIOS settings or Windows power profiles. The low 15 W ceiling also explains the slower-than-expected performance as mentioned in the Processor section above.
Core temperature would stabilize at just 55 C when running Witcher 3 compared to 70 C on the much faster Beelink SER6 Pro.
CPU Clock (GHz) | GPU Clock (MHz) | Average CPU Temperature (°C) | |
System Idle | -- | -- | 43 |
Prime95 Stress | 1.8 | -- | 55 |
Prime95 + FurMark Stress | 1.4 | 200 | 55 |
Witcher 3 Stress | ~0.5 | ~1237 | 53 |
System Performance
PCMark results are behind many current mini PCs running on latest gen processors such as the GMK NucBox K6 or Intel NUC 13 Pro. The Digital Content Creation subtest score is especially lower due to the slow integrated GPU.

Storage Devices
Much like on the NucBox M4, the M5 ships with a Lexar PCIe4 x4 NVMe SSD for steady transfer rates of up to 3600 MB/s. Sequential write speeds are quite good as well at 3100 MB/s to be one of the better midrange PCIe4 SSDs.

GPU Performance — Outdated Radeon RX Vega 8
The integrated Radeon RX Vega 8 predates the Radeon 680M and 780M that now dominate midrange or higher mini PCs and laptops. It's significantly slower than the Radeon 680M by about 50 to 60 percent to be more in line with the Iris Xe Graphics G7 96EUs on 11th gen Intel CPUs. The Radeon RX Vega 8 cannot run most games locally at reasonable frame rates.

Emissions
System Noise
Fan noise is always present at a floor of 33.8 dB(A) no matter the onscreen load or profile setting. The quiet whir is audible in an HTPC environment like the living room, but it's not loud enough to be distracting.
Fan RPM range is thankfully quite narrow and so the difference between maximum and minimum fan noise is relatively small. For example, we're able to record a maximum of just 37 dB(A) compared to over 48 dB(A) on the NucBox K6 or Acemagic F2A.

Power Consumption
Running Witcher 3 to represent typical high loads would draw around 35 W or just under half of what the NucBox K6 demands. The power savings are enough to make the NucBox M5 more efficient than most other mini PCs which also correlate with the low maximum fan noise and TDP ceiling. However, CPU and GPU performance suffer as a result.
The model ships with a much smaller (~6.8 x 6.8 x 3.2 cm) 65 W AC adapter when compared to the 130 W adapter that ships with the NucBox K6. Third-party USB-C AC adapters are supported.

Pros

Verdict — Better Options Are Available
The NucBox M5 currently retails for $300 to $380 with RAM and storage. Meanwhile, the NucBox K6 can be found for $500 while offering 2x to 2.5x the CPU and GPU performance without being any bigger or heavier. Needless to say, it's hard to recommend the NucBox M5 when GMktec already offers an objectively better alternative for not that much more. Even outside of GMK, the Beelink SER6 can be found for under $500 with much faster performance than the NucBox M5.
The NucBox M5 isn't necessarily a bad system, but there are a handful of much faster mini PCs available for the same <$500 price range.
There are some standout features of the NucBox M5 including the dual 2.5 Gbps RJ-45 ports, dual fans, and SSD heatsink all of which are relatively uncommon on budget mini PCs. Nonetheless, the poor performance-per-dollar overshadows any advantages the model might have.
