GEEKOM A5 Review – Part 2: Windows 11 Pro tested on an AMD Ryzen 7 5800H Mini PC

After unboxing GEEKOM A5 mini PC, checking out the hardware, and booting the device in the first part of the review, we’ve now had time to further test the AMD Ryzen 7 5800H mini PC with Windows 11 Pro operating system.

The boot-up is quite fast and generally speaking the device performs well for the various tasks we ran on the mini PC. So in the second part of the GEEKOM A5 review, we will provide an overview of the system information, test features, perform benchmarks, check heat dissipation under load, and measure the power consumption of the mini PC while running on Windows 11 Pro.

Software Overview and Feature Testing

Going to System->About in Windows settings, we can confirm that the GEEKOM A5 mini PC is equipped with an AMD Ryzen 7 5800H processor clocked at 3.20 GHz (base frequency)  and 32GB of RAM, and runs Windows 11 Pro 64-bit.

The PL1 and PL2 power limits are set to 42W (PBP) and 60W (MTP) respectively, while the AMD Ryzen 7 5800H processor has a TDP of 45, so it looks like GEEKOM may have lowered the power limit slightly for better cooling in this compact form factor.

The GEEKOM A5 mini PC comes with a 512GB M.2 SSD, but we also added a 128GB SATA SSD (CHUANG JIU CJ225128TC) in the slot under the bottom cover.

SATA SSD installation GEEKOM A5 mini PC

It shows up properly in Device Manager along with the 512GB Lexar NM620 SSD that is preinstalled in the system.

CrystalDiskMark reports 229 MB/s sequential read speed and 160MB/s sequential write speed for the (cheap) SATA SSD, which matches the I/O performance we got with the ODROID-H2 SBC in Ubuntu Linux a few years ago.


The Device Manager’s Network adapters section shows 2.5GbE (Realtek), WiFi 6 (RTL8852BE), and Bluetooth hardware.

We can check the version of Bluetooth in the Device Manager by going to the Advanced tab of the Realtek Bluetooth Adapter Properties window. The “LMP 12” string in the Firmware version looks up to Bluetooth 5.2 as advertised in the specifications.

Geekom A5 Bluetooth Version

Many mini PC manufacturers have unclear specifications and no markings for USB ports, but GEEKOM is quite better because they have clear markings with speeds and features on each of the USB ports. But let’s test all USB ports to confirm the three USB USB 3.2 Gen 2 Type-A ports and two USB 3.2 Gen 2 Type-C ports can indeed achieve 10 Gbps as advertised. We will be using the ORICO M234C3-U4 M.2 NVMe SSD enclosure for testing together with HWiNFO64 to check the USB version and speed, and CrystalDiskMark to confirm the speed.

USB 3.2 Gen 2 Type A speed
USB 3.2 Gen 2 front panel, left side

The two USB ports at the front are USB 3.2 ports with USB 3.1 SuperSpeedPlus speed (10 Gbps) and CrystalDiskMark helps us confirm that with 927.93 MB/s read speed. Both ports on the front have about the same performance.

USB Type-A port GEEKOM A5’s rear panel

The single USB 3.2 Type-A port on the rear panel has the same characteristics (USB 3.2 10Gbps), but the performance is slightly better at 964MB/s, so although the performance difference is not dramatic,  we’d recommend using that port instead of the ones on the front panel with external NVMe storage in order to get the best possible performance.

GEEKOM A5 USB 3.2 Gen 2 Type-C performance

Both USB Type-C ports also support USB 3.2 version with USB 3.1 SuperSpeedPlus (10 Gbps) speed, and CrytalDiskMark results are similar to the Type-A port above with a 964 MB/s read speed.

USB 2.0 test CrystalDiskMark

Finally, we tested the USB 2.0 Type-A port on the back with another USB hard drive, as the ORICO SSD enclosure does not work with USB 2.0 ports (on any machine), and the results are as expected with USB 2.0 High Speed (480 Mbps) and around 44MB/s read speed.

GEEKOM A5 video output USB C HDMI 2.0

The GGEKOM A5 mini PC can support up to 4 independent displays with two USB 3.2 Gen 2 Type-C (8K) ports and 2 HDMI 2.0 (4K) ports.

GEEKOM A5 mini PC with 3 Displays

We did not quite have four monitors for this review, but we successfully used three monitors with the one on the left being the 10.1-inch “RPI All-in-One” touchscreen display (HDMI) and the one on the right being the CrowView 14-inch laptop monitor (USB-C). The VGA monitor in the middle is connected through an HDMI to VGA adapter.

GEEKOM A5 Windows 11 Benchmarks

We’ve set the Power mode to “Best performance” before running a range of benchmarks to test the performance of the GEEKOM A5 mini PC in Windows 11 Pro. Note that the ambient temperature ranged from 28 to 30°C, so the results or results of other reviews may be different especially for multi-core benchmarks due to potential CPU throttling.

Let’s start with PCMark 10 benchmarks.

GEEKOM A5 mini PC PCMark 10 benchmark

The system got 6,554 points in PCMark.

GEEKOM A5 mini PC 3DMark

4,157 points in 3DMark’s Fire Strike.

Geekom A5 Passmark Performance Test 11

The A5 achieved 4,526.8 points in PassMark PerformanceTest 11, but note that this specific benchmark is heavily influenced by storage performance, and the 512GB SSD installed in the system is pretty good. As we can confirm with CrystalDiskMark with 3.4 GB/s and 3.1 GB/s sequential read and write speeds respectively, and good random I/O performance too.

Lexar SSD CrystalDismark

Cinebench R23 was used to test single-core and multi-core performance.

GEEKOM A5 review Cinebench R23 benchmark

GEEKOM A5 got 10,146 points in the multi-core benchmark, and 1,397 points for the single-core benchmark.

We started GPU testing with Unigine Heaven Benchmark 4.0 where the system averaged 41.6 fps at 1920×1080 resolution.

Next, we’ll test 4K and 8K video playback in Google Chrome.

YouTube 4K Chrome GEEKOM A5

YouTube 4K (30 fps) video playback is very smooth but virtually no frame dropped. As the screenshot above shows, that video used the VP9 video codec.

YouTube 8K GEEKOM A5

But that’s another story with YouTube 8K (60 fps). We played the video for about 21 minutes 27,462 frames were dropped out of 77,107 frames. This time around, YouTube did not use VP9, but the newer AV1 codec.

Let’s compare some of Windows 11 benchmark results from the GEEKOM A5 against some other mini PCs we’ve reviewed in recent months, namely the GEEKOM IT11 (11th Gen Core i7-11390H Tiger Lake), GEEKOM AS 6 (AMD Ryzen 9 6900HX), and Khadas Mind (13th Gen Core i7-1360P Raptor Lake). All were tested in similar environmental conditions (28-30°C room temperature). But first a quick summary of the main features of the four mini PCs.

Default OSWindows 11 ProWindows 11 ProWindows 11 ProWindows 11 Home

It’s not quite a fair fight, as the GEEKOM A5 is the cheapest of the lot, and the Khadas Mind and AS 6 mini PC sell for about twice the price, but it’s still interesting to see how much difference throwing more money at a mini PC makes… Now the results:

GEEKOM A5 holds its own and offers a good price/performance ratio, although part of the lower price can be attributed to the smaller capacity SSD and the lack of features such as Thunderbolt/USB4 ports.

Network (WiFi 6 and 2.5 GbE) performance

Let’s test the performance of the 2.5GbE interface with iperf3 and UP Xtreme i11 mini PC on the other side.

  • Upload:
  • Download:

All good. Now let’s test WiFi 6 performance using Xiaomi Mi AX6000 router.

  • Upload
  • Download

WiFi 6 performance using the 5 GHz ESSID averaged 438 Mbps upload and 404 Mbps average download. That’s not outstanding, but still pretty good, and importantly performance was stable during each of the 60-second tests.

Thermal design

We checked the thermal design, or cooling performance, to check CPU Throttling in Windows 11 with HWiNFO64, CPUID HWMonitor, and 3Dmark’s Fire Strike benchmark. The CPU reached 101°C in a room with an ambient temperature of 28-30°C, but somehow no thermal throttling was detected in HWiNFO64 as the junction temperature of the AMD processor is 105°C.

Fan noise

The mini PC has a very quiet fan during idle or lightweight tasks, but it becomes quite louder while playing a YouTube 8K video in Chrome. When stressing the system with benchmarks, the fan is quite loud and can clearly be heard from a few meters away.

We measured the noise with a sound level meter placed approximately 5 cm from the top of the device:

  • Normal work, general web browsing: 39-41.5 dBA
  • 3DMark Fire Strike: 51.0-56.6 dBA

The sound level meter measures 37-38 dBA in the room when everything is quiet.

GEEKOM A5 power consumption

Power consumption was measured with a wall power meter as follows:

  • Power off – 0.5 Watts
  • Boot – 40-70 Watts
  • Idle – 9 – 12 Watts
  • Web browsing – 12 to 31 Watts
  • 3Dmark Fire Strike – 32 to 58 Watts
  • Video playback – 32 to 68 Watts (8K60 YouTube video in Chrome)


The GEEKOM A5 mini PC performed well in Windows 11 Pro in most of your tests, and the mini PC offers plenty of USB ports for expansion with three USB 3.2 10 Gbps Type-A ports, two USB 3.2 10Gbps Type-C ports with DisplayPort alt mode, and a USB 2.0 Type-A port. The mini PC is suitable for a wide range of tasks such as office work, online learning, 4K video streaming, and light gaming. However, it struggles with 8K YouTube videos, which may not be such a big issue for most unless you connect an 8K display over USB-C (limited to 30 Hz). The fan noise may be an issue for some, as while it’s quiet when idle and web browsing, more demanding tasks will make the fan turn much faster and it will become quite noisy. That’s all for today, for we’re not done yet with the GEEKOM A5, as we’ll install Ubuntu 22.04 next in order to test Linux on the AMD mini PC.

We’d like to GEEKOM for sending the A5 mini PC for review. The model showcased here with an AMD Ryzen 7 5800H processor, 32GB RAM, and a 512GB M.2 SSD can currently be ordered on Amazon for $399 but you can use the coupon code X4OCFLPW for an additional $40 discount, or alternatively, the mini PC can also be purchased on GEEKOM online store for $359 when using cnxsofta540 coupon code.

    1. It looks like GEEKOM will use Lexar memory for their more expensive models, and Wodposit memory for cheaper ones. I’m not sure to what extent it matters.

  1. Just a quick heads-up for people wanting to use Ubuntu on the GEEKOM A5. WiFi is not stable. It’s possible to connect to 2.4/5GHz access points but within a few minutes, the connection is lost. There might be a workaround but I haven’t had time to look into it just yet. We’re reviewing the system with Ethernet for now (through a repeater).
