Minisforum UM790 Pro Mini PC vs Geekom A8 Mini PC

The UM790 Pro is the faster machine: its Ryzen 9 7940HS boosts to 5.2 GHz and its two USB4 ports support external GPUs, fast storage and 8K output. The Geekom A8 uses the closely related Ryzen 7 8745HS with the same Radeon 780M graphics, but adds Wi-Fi 6E and a smaller 4.42-inch square chassis. Owners of both report solid build for the size; the UM790 Pro runs hotter and louder under sustained load, while the A8 is the quieter, tidier desk box. Buy the Minisforum for CPU-heavy work and eGPU or 8K setups; buy the Geekom for a compact, well-connected everyday desktop.

  • Choose the UM790 Pro if you want the fastest CPU here, two USB4 ports for an external GPU or 8K display, and room for a second M.2 SSD.
  • Choose the Geekom A8 if you want a smaller, quieter box with Wi-Fi 6E and support for up to 64 GB of RAM and 2 TB of storage.

What reviewers say

Minisforum UM790 Pro Mini PC

Reviewers and owners generally praise the UM790 Pro for its strong CPU performance and compact design, often highlighting its value as a small form factor PC. Some complain about fan noise during intensive tasks and note that the integrated graphics are not for high-end gaming.

What people mention
  • PerformancePraisedOwners find the Ryzen 9 7940HS handles multitasking and demanding applications well.
  • Fan noiseCriticisedSome users report the fan becomes noticeable during heavy workloads.
  • GraphicsMixedThe Radeon 780M is fine for casual gaming but not for high-end titles at high settings.
  • Port selectionPraisedReviewers appreciate the two USB4 ports and dual HDMI outputs for multiple displays.

Questions and answers

Which is better for gaming?
Both use the Radeon 780M, so built-in gaming performance is close and fine for esports and older titles at 1080p. The UM790 Pro wins for serious gaming because its USB4 ports let you attach an external GPU, which the A8 cannot do.
Which is better for video editing and 3D work?
The UM790 Pro. Its 7940HS has higher clocks and a second M.2 slot for a fast scratch drive, and USB4 handles fast external storage. The A8 is capable but slower on long renders.
Is the Geekom A8 worth stepping up to over the UM790 Pro?
Only if size, noise and Wi-Fi 6E matter more than raw speed and ports. The A8 is the tidier desk machine; the UM790 Pro is the more expandable one.
Which runs cooler and quieter?
The Geekom A8. Its smaller chassis is tuned for quieter light-load running, while the UM790 Pro's higher clocks make its fans audible under sustained load.
Can I upgrade the RAM and storage on both?
Yes. Both use socketed DDR5 SO-DIMMs and M.2 2280 PCIe 4.0 SSDs. The UM790 Pro adds a second M.2 slot; the A8 is rated for up to 64 GB of RAM.
Do either support multiple 4K monitors?
Yes. The UM790 Pro drives two 4K@60Hz HDMI displays plus USB4 output. The Geekom A8 supports up to four 4K displays across its HDMI 2.0 ports and USB-C output.
