GEEKOM A5 Pro 2026 Edition Review – Part 3: Ubuntu 25.10 on an AMD Ryzen 5 7530U mini PC

After checking out the hardware with an unboxing and a teardown of the GEEKOM A5 Pro 2026 Edition mini PC, and testing it with the pre-installed Windows 11 Pro OS in the second part of the review, we will now report our experience with Ubuntu 25.10 to show how the AMD Ryzen 5 7530U mini PC performs under Linux.

The Ubuntu 25.10 review includes an overview of the system, benchmarks, storage and networking (2.5GbE and WiFi 6) performance testing, and measurements of CPU temperature under stress, fan noise levels, and power consumption of the mini PC under various workloads.

Ubuntu 25.10 installation

We decided to install Ubuntu 25.10 in dual boot configuration alongside Windows 11. To do so, we first shrank the Windows partition (C:) to roughly half its original size, before inserting a USB drive with the Ubuntu 25.10 ISO to carry on with the installation.

The installation proceeded smoothly on this mini PC, and we didn’t have to enter the BIOS after installation to change the boot priorities, like we sometimes have to do.

GEEKOM A5 Pro 2026 Edition system information on Ubuntu 25.10

Goingto Settings → About, we can confirm we have a GEEKOM A5 Pro model powered by a 12-thread AMD Ryzen 5 7530U processor with Radeon Graphics, 16GB memory, and a 1 TB drive. The system runs Ubuntu 25.10 64-bit with GNOME 46, Wayland compositor, and Linux 6.17 kernel.

We can get a few more details in the terminal:


And even more using the inxi utility:


Everything looks properly detected. An AMD Ryzen 5 7530U 6-core/12-thread processor clocked up to 4548 MHz, 16GB RAM, a 465.13 GB rootfs on the WPBSN4N8-1TGP SSD (953.97 GB), 2.5GbE using Realtek RTL8125, and Wi-Fi 6 and Bluetooth 5.2 using a Realtek RTL8852BE wireless module. The idle CPU temperature is reported to be 50.1°C, but we will test this in more detail later on.

Ubuntu 25.10 Benchmarks on GEEKOM A5 Pro 2026 Edition mini PC

We’ll start Ubuntu 25.10 benchmarks with Thomas Kaiser’s sbc-bench script:


The 7-zip benchmark started at 38,503 MIPS for the first run, before dropping to 35,443 MIPS for the second, and 35,160 for the third, with an average of  36,370 MIPS. This seems to indicate power limits were reached rather than thermal limits, since the CPU temperature never exceeded 75.9°C as reported in the full log. It’s interesting to note that single-core workloads result in higher CPU temperatures…


… compared to multi-core workloads due to (I assume) power limits kicking in:


Talking about power limits, we installed the ryzenadj script to check those:


Here are the key values:

  • STAPM LIMIT – 15 Watts (TDP)
  • PPT LIMIT FAST – 25 Watts, equivalent to MTP/PL2
  • PPT LIMIT SLOW – 20 Watts, equivalent to PBP/PL1

For reference, the power limits in Windows were the same at 20W (PBP/PL1) and 25W (MTP/PL2).

Geekbench 6.6.0 was used to test the single-core and multi-core performance of the AMD Ryzen 5 7530U CPU.

GEEKOM A5 Pro 2026 Edition Geekbench 6.6.0

The computer achieved a single-core score of  1,980 points and a multi-core score of 7,024 points.

The GPU was tested with Unigine Heaven Benchmark 4.0. The AMD Ryzen 5 7530U mini PC could render the benchmark at 27.2 FPS and a score of 686 points at a standard 1920×1080 resolution.

Time to check YouTube 4K and 8K video playback in Firefox and Chrome web browsers.

A YouTube 4K 60FPS video could play smoothly in Firefox, albeit with some dropped frames: 744 out of 17,761.

It was easier at 4K 30FPS with almost no dropped frames (only 3 over 5 minutes).

Google Chrome performed a little better with the YouTube 4K 60FPS video since there were 82 frames dropped out of 17,533. It’s still hard to visually tell the difference between Firefox and Chrome.

When switching to YouTube 8K 30 FPS, both Firefox (350 frames dropped out of 749)…

… and Chrome (136 frames dropped out of 988) struggled, and the video was choppy and not watchable.

It’s the same experience as in Windows, and means the GEEKOM A5 Pro 2026 Edition mini PC works well with YouTube 4K videos, but is not suitable for 8K YouTube video streaming, even at 30 FPS.

We’ll now evaluate web browsing performance with Speedometer 2.0 on Firefox. The mini PC managed 352 runs per minute.

GEEKOM A5 Pro 2026 Edition Ubuntu 25.10 benchmark results compared to other mid-range mini PCs

Now that we have some benchmark results on Ubuntu 25.10 for the GEEKOM A5 Pro 2026 Edition, we’ll compare it to other mid-range mini PCs we tested with Linux (Ubuntu 22.04/24.04), namely the Beelink EQi13 Pro (Intel Core i5-13500H), GEEKOM A6 (AMD Ryzen 7 5800H), and GEEKOM A5 (AMD Ryzen 7 5800H).

Here’s a summary of the key specifications for the four systems.

All four devices are in a similar $550 – $650 price range. The GEEKOM A5 Pro 2026 Edition features a hexa-core processor, so it’s expected to struggle in multi-core benchmarks against octa-core and 12-core processors. Let’s see if this is confirmed by the benchmark results.

Multi-core benchmarks (7-Zip and GeekBench 6.6 multi-core) are indeed impacted, but we can also see weaknesses in terms of memory bandwidth and 3D graphics performance.  The single-core performance of the GEEKOM A5 Pro 2026 Edition is similar to that of  GEEKOM A5, and the only real positive is the improved web browsing score with Speedometer 2.0, but that could be due to web browser performance improvements over time rather than the hardware. Our conclusion at this stage is the same as in Windows 11: “the earlier GEEKOM A5 looks like a better deal if you can live with a smaller capacity 512GB NVMe SSD”.

Storage and USB performance

We tested the 1TB NVMe SSD using iozone3:


Results were 3,520 MB/s for sequential reads and 3,272MB/s for sequential writes, which compares to 3,720 MB/s and 3,434 MB/s, respectively, using CrystalDiskMark on Windows 11.

We also tested the USB 3.2 Gen 2 Type-A/C ports on the mini PC with an ORICO M234C3-U4 M.2 NVMe SSD enclosure and the single USB 2.0 Type-A port with a Seagate USB HDD, as well as lsusb and iozone utilities.

For reference, here are the results for the front left USB 3.2 Type-A ports:


and the USB 2.0 port:


Summary for all six ports from left to right:

  • Front panel
    • USB-A #1 – USB 3.2 – 10 Gbps – Read speed:  870 MB/s; write speed: 771 MB/s
    • USB-A #2 – USB 3.2 – 10 Gbps – Read speed: 866 MB/s; write speed: 773 MB/s
  • Rear panel
    • USB-C #1 – USB 3.2 – 10 Gbps – Read speed: 900 MB/s; write speed: 798 MB/s
    • USB-A #1 (top) – USB 3.2 – 10 Gbps – Read speed: 910 MB/s; write speed: 794 MB/s
    • USB-A #2 (bottom) – USB 3.0 – 480 Mbps – Read speed: 42 MB/s; write speed: 31 MB/s
    • USB-C #2 – USB 3.2 – 10 Gbps – Read speed: 911 MB/s; write speed: 792 MB/s

The results are mostly as expected/advertised. It looks like the USB 3.2 Type-A ports on the front panels are slightly slower than the ones on the rear panel.

2.5GbE, WiFi 6, and Bluetooth 5.2

We’ll now test 2.5GbE and 5GHz WiFi 6 networking performance on the GEEKOM A5 Pro 2026 Edition running Ubuntu 25.10 using iperf3.  We’ll start with the 2.5GbE port using an UP Xtreme i11 Edge mini PC on the other side.

  • Download
  • Upload
  • Full-duplex (bidrectional)

The results are perfect at 2.35 Gbps in all conditions.

Let’s now switch to 5 GHz WiFi 6 testing, adding a Xiaomi Mi Router AX6000 router to the mix.

  • Download
  • Upload

814 Mbps for downloads and 474 Mbps for uploads is similar to what we got in Windows. Not outstanding, but it should do for most people, especially considering this is a mid-range mini PC.

We also quickly tested Bluetooth 5.2 by successfully transferring a file between the GEEKOM A5 Pro and a Redmi Note 14 Pro 5G smartphone.

Thermal performance of the GEEKOM A5 Pro 2026 Edition

In order to evaluate the thermal performance/cooling efficiency of the GEEKOM A5 Pro 2026 Edition mini PC, we ran a stress test on the 6-core/12-thread AMD Ryzen 5 7530U SoC while monitoring CPU temperature and frequency with Psensor temperature monitor and sbc-bench.sh script.

GEEKOM A5 Pro 2026 Edition Ubuntu stress test

The test results show that the CPU maintains a consistent clock speed of around 2.6 GHz under full load, with the CPU temperature remaining in a 64–66°C range in a room at about 28°C. There’s plenty of legroom, and people wanting to extract a bit more performance may consider increasing PL2, although this should increase power consumption.

Fan noise

Since the GEEKOM A5 Pro 2026 Edition is one of the quieter actively cooled mini PCs I’ve tested. We measured the fan noise with a sound level meter placed around 5 centimeters from the top of the device:

  • Idle – 37.7 – 38 dBA (fan off)
  • Stress test on all 12 threads – 47.7 – 48.1 dBA for the initial ~10 seconds, after which the noise level drops and stabilizes at around 39.3 – 40.5 dBA for ~30 seconds, repeating in cycles.

For reference, the meter measures around 36.6 – 37.0 dBA in a quiet room. During typical everyday use, the mini PC’s fan is practically inaudible.

GEEKOM A5 Pro’s power consumption on Ubuntu 25.10

We finally measured the power consumption with a wall power meter:

  • Power off – 0.7 Watts
  • Idle – 3.8 – 4.4 Watts
  • Video playback – 28.0 – 29.1 Watts (YouTube 4K 60FPS in Firefox)
  • CPU stress test (stress -c 12)
    • First few seconds – 35.9 – 36.7 Watts
    • Longer runs – 24.0 – 24.3 Watts

Note: During the testing, the mini PC was connected to Wi-Fi 6, a USB RF dongle for a wireless keyboard and mouse combo, and a GAOMON PD2200 Pen Display 21.5-inch drawing tablet via one of the HDMI ports.

Conclusion

The GEEKOM A5 Pro 2026 Edition mini PC worked reasonably well on Ubuntu 25.10, and we didn’t encounter any major issues. In other words, it performs about the same in Linux as in Windows 11 Pro, supports multi-monitor setups up to 4 displays via HDMI and USB-C (DisplayPort) ports, handles YouTube 4K video playback well up to 60 FPS, and delivers good network performance through 2.5GbE and WiFi 6.

The mini PC never throttles due to excessive temperature, consumes less power than most other mini PCs we’ve reviewed, and the fan is pretty quiet, even under load. Coolness and quietness are nice, but the mini PC’s performance is on the low side at this price point, especially for multi-core workloads (partially due to the 6-core/12-thread CPU), 3D graphics performance, and memory bandwidth. The system can not handle YouTube 8K videos either, even at 30 FPS, but 4Kp60 YouTube videos play just fine.

The summary for Linux is the same as in Windows. The GEEKOM A5 Pro 2026 Edition is suitable for people wanting a fairly quiet mini PC (bearing in mind it’s not fanless) and care about power consumption and want to avoid thermal throttling even in hotter climates. If those metrics are not important, and you prefer higher performance at a similar price, the GEEKOM A5 looks to be a better option, and we’ve previously seen that it also works well on Ubuntu. (We had an issue with WiFi in Ubuntu 22.04, but it should now be resolved with a more recent Linux kernel).

We’d like to thank GEEKOM for sending the A5 Pro 2026 Edition mini PC for review. It can be purchased for $569 on the GEEKOM US store, or $549 on Amazon ,or 619 Euros on the GEEKOM DE store. You can also use CNXA5PRO coupon to get a 7% discount in the US stores.
