The MINISFORUM UM890 Pro pairs an AMD Ryzen 9 8945HS with Radeon 780M integrated graphics, dual USB4, OCuLink, dual 2.5GbE, and room for two memory modules and two SSDs. Those features make it a well-connected, upgradeable mini PC on paper. The available information establishes the manufacturer’s specifications, not hands-on results: noise, temperatures, sustained performance, gaming frame rates, and real-world eGPU behavior remain unverified.
What the UM890 Pro offers
MINISFORUM lists the UM890 Pro with an AMD Ryzen 9 8945HS processor, integrated Radeon 780M graphics, and an unusually broad set of expansion and connection options for a compact desktop. The specifications below are manufacturer claims from the MINISFORUM UM890 Pro product page, accessed in 2026; they should not be read as independent test results.
| Component | MINISFORUM-listed specification |
|---|---|
| Processor | AMD Ryzen 9 8945HS; 8 cores and 16 threads; 16 MB cache; boost up to 5.3 GHz |
| Graphics | AMD Radeon 780M integrated graphics |
| Memory | Two DDR5 SODIMM slots; dual-channel operation; up to 5600 MHz and up to 96 GB total |
| Storage | Two M.2 2280 PCIe 4.0 SSD slots |
| Wired networking | Two 2.5G RJ45 Ethernet ports |
| Wireless | Wi-Fi 6E and Bluetooth 5.3 |
A supported maximum of 96 GB does not establish that every 96 GB kit or configuration has been tested. Likewise, the listed CPU boost is a specification, not evidence that the processor sustains that speed under a particular workload.
Ports, displays, and expansion
The official listing names two USB4 ports, one HDMI 2.1 port, one DisplayPort 1.4 port, OCuLink, four USB 3.2 Gen 2 Type-A ports, and two 2.5G Ethernet ports. That combination can suit a desk setup with fast peripherals, wired networking, and multiple display connections, while OCuLink offers a route to investigate external graphics.

MINISFORUM says the UM890 Pro supports up to four simultaneous displays. Its listed video connections are HDMI, DisplayPort, and USB4. That four-display statement does not specify a guaranteed resolution and refresh rate for every combination; check the monitor, cable, adapter, and desired settings before planning a particular multi-monitor layout. TechRadar also calls out the model’s USB4, OCuLink, dual 2.5GbE, and four-screen support in its Windows mini PC alternatives roundup.
USB4 for peripherals and storage
Two USB4 ports provide a connection option for compatible high-speed accessories and displays. The specifications alone do not establish transfer speeds with a particular external SSD, dock, or cable, or whether a specific accessory will work as expected. Confirm the requirements of the device you plan to attach.

OCuLink and external graphics
OCuLink gives the UM890 Pro a potential external-GPU path, but the port is only one part of an eGPU setup. Verify dock compatibility, GPU fit, power supply inclusion and capacity, and cable requirements before buying. No particular dock, graphics card, or eGPU performance result is established here.

What the specifications mean for everyday use
The Ryzen 9 8945HS and Radeon 780M identify the core compute and graphics hardware, while the port selection and upgrade slots define much of the system’s flexibility. These details help narrow whether the machine fits a planned workspace or upgrade path. They do not establish how quickly it completes a workload, how quietly it runs, or how well it performs in a game.
For local AI or LLM use, the relevant questions include the model, quantization, memory use, and inference speed. A community thread asks whether owners are running LLMs on the UM890 Pro, but discussion and questions are not controlled performance evidence. See the r/LocalLLaMA discussion as anecdotal context, not as a benchmark. The integrated graphics specification alone cannot answer how a particular model will perform.
