MINISFORUM UM790 Pro Mini-PC with AMD Ryzen 9 7940HS APU tested

Published: Aug 4th 2023, 11:53 GMT

Minisforum flagship Ryzen Mini-PC tested

A smaller computer featuring 8-core Zen4 CPU and capable integrated RDNA3 graphics. 

A few weeks ago, Minisforum has unveiled its most high-performance Mini-PC of the year, at least up to this point. While the company is already developing its Ryzen 7045HX “Dragon Range” series, which will boast twice the number of cores, the Ryzen 7040HS based Mini-PC is the fastest system Minisforum has to offer at the time of writing.

This system packs an AMD Phoenix APU known as Ryzen 9 7940HS, featuring the Zen4 architecture. It holds the position of AMD’s flagship APU in this current generation. It incorporates a powerful 12 CU RDNA3 architecture, representing AMD’s latest and fastest integrated GPU design. This fusion of powerful CPU and GPU architectures results in an energy-efficient answer that proves valuable across a range of applications, including laptops, mini-PCs, and even handheld consoles.

Retail version of UM790 PRO

Given our recent evaluation of a similar system (Beelink GTR7 Pro), we will draw comparisons between the two devices in terms of features and performance. It’s worth mentioning that our original intention was to encompass both systems in a single review. However, Beelink openly rejected this proposition, while Minisforum, a partner we’ve collaborated with for several years, displayed no objection to such comparative assessments.

Noteworthy is the distinction in our pre-release model, featuring a different logo. In the final iteration, Minisforum has included a more streamlined and darker logo design. You can see how the device looks in retail above (featured image has our unit).

The Phoenix APU comes equipped with 8 cores and 16 threads, all following the standard ‘big’ core design. This sets it apart from Intel’s Alder/Raptor Lake series, which features a hybrid design combining Performance and Efficient core types. The maximum boost clock for all cores is 5.2 GHz, and they are initially configured to operate at 45W power.

Notably, Minisforum has chosen to raise the TDP to 54W as the default setting, with the option for further adjustments in the BIOS. For our testing purposes, we will adhere to the default configuration, which also entails maintaining the shared system memory at 2GB for the integrated GPU.

The standout feature is the integrated graphics, boasting 12 Compute Units (768 Stream Processors) with a clock speed of up to 2.8 GHz. This GPU is paired with DDR5-5600 CL46 memory, a factor that significantly influences overall performance, as many are aware.

The system packs Apacer DDR5-5600 memory, in our case two 8GB modules running in dual channel configuration. The system was equipped with two 256GB Kingston PCIe Gen4 M.2 2280 solid-state drives which can be used in Raid 1 or Raid 0.

Another important aspect is the inclusion of two USB4 Type-C connectors, which not only provide compatibility with external GPUs but also support Power Delivery in both directions. This feature eliminates the need for a cumbersome power supply, enabling the system to utilize a compact charger. Nevertheless, it would be even more advantageous if this power setup were the default choice, and the PC was bundled with a smaller GaN charger similar to what the competition offers.

Size comparison Minisforum UM790 Pro vs. Beelink GTR7 Pro

When contrasted with the Beelink GTR7 Pro, which boasts identical AMD hardware, the Minisforum presents a smaller footprint, albeit with a slightly taller design. Additionally, the Minisforum system emits a slightly higher noise level, while the Beelink counterpart incorporates numerous venting holes for enhanced ventilation.

One shared feature between both systems is the utilization of a dual-fan arrangement. The primary fan is dedicated to cooling the APU, while the secondary fan serves to dissipate heat from SSDs and memory modules. This dual-fan configuration seems to be an emerging trend among these devices, driven by the growing need to manage increasing storage temperatures and faster memory performance.

What’s included (accessories)

The system comes with an HDMI cable, VESA mount, charger and region-specific power cable. There are also two extra rubber stands which were added for a good reason.

The primary inconvenience arises from the somewhat bothersome access to the storage and memory components, as the screws are concealed beneath the four rubber feet. It’s possible that over time, the adhesive holding these rubber stands in place might deteriorate. It would be better if four additional stands were added, as a precautionary measure.

Apart from this minor inconvenience, the system otherwise offers straightforward access to its internal components. However, we advise using plastic pry tools for disassembly as the backplate is clipped to the chassis. Furthermore, one should make sure to disconnect the fan header and be cautious not to tear the soldered wireless network cables.

At this point, it’s advisable to conclude the disassembly process as the cooler is outfitted with liquid metal. Continuing further wouldn’t yield significant benefits. This serves as a reminder that reapplying liquid metal is a task that can prove challenging for individuals who are using this method for the first time.

Testing methodology

CPU capabilities, thermals and power consumption are the focus of this short evaluation. Since this is a gaming Mini-PC our primary goal was to test some popular and heavy titles on this device.

Software used for this review

  • 3DMark Professional Edition
  • TechPowerUP GPU-Z
  • CPU-Z 2.06.0
  • HWiNFO 7.46-5110
  • CapFrameX 1.7.1
  • Custom software developed by

For the purpose of comparing GTR7P versus UM790P, we have conducted a retest of the GTR7 Pro using the most recent AMD driver. Despite the testing, no significant changes in performance were observed.

Clocks and thermals

The UM790 Pro tends to exhibit slightly higher noise levels and temperatures in comparison to the GTR7 Pro. While the idle temperature and CPU package power metrics are nearly identical, under heavy load, the UM790 Pro registers temperatures at least 3°C higher and operates at slightly lower clock speeds. However, this outcome was anticipated considering the UM790 Pro’s smaller size and the inherent reduction in its default power configuration.

The UM790 PRO powered by AMD Ryzen 9 7940HS processor boasting Zen4 and RDNA3 architectures, reveals itself as a capable everyday desktop replacement for certain tasks. This processor even showcases an ability to handle some less demanding games, achieving medium to high settings depending on specific game requirements.

The use of liquid metal instead of traditional thermal compound for CPU and active cooling for memory and SSD are definitely worth a mention. As we delve into the comprehensive review of the UM790 Pro, it becomes apparent that its standout feature is the multitude of connectivity options it offers. All that while retaining of a smaller 10th generation Core counterpart from the same company that we tested. This size advantage doesn’t compromise its capabilities, as it accommodates eGPU support through a USB4 port.

Although the internals of the mini-PC are easily accessible, a slight complication arises due to the hidden screws beneath glued stands. This factor introduces a modest level of complexity when it comes to disassembly.

Display connectivity is a point of consideration, with the UM790 Pro exclusively supporting HDMI or USB (DisplayPort) connections. The absence of a native full-sized DisplayPort connector or adapter might present limitations for users reliant on this specific interface. The inclusion of a relatively large and heavy power supply is balanced by the mini-PC’s support for USB power delivery, adding convenience to its feature set.

Additionally, the UM790 Pro stands out for its support of SSD RAID0 and RAID1 configurations, bolstered by the inclusion of dual SSDs in our tested unit. And speaking of users’ convenience, there is also a graphical BIOS with a user-friendly interface, or alternatively complete version with unlocked settings.

The UM790 Pro mini-PC’s combination of AMD’s latest technology, wide connectivity options, innovative cooling, and performance-enhancing features makes it one of the leaders in the world of mini-PCs. However, it has failed to impress us after reviewing the GTR7 Pro, which is also a bit more powerful and even runs at lower temperatures.

At the time of writing, a barebone UM790 PRO system was retailing at $519, with 32GB RAM/512GB SSD option going for $669. There are also options with 1TB SSD ($699) and 64GB memory at $789. Our variant with 16GB configuration was not listed.
