Minisforum UM890 Pro Review – Ryzen 9 Mini PC Power
If you’ve been watching the mini PC space closely, you already know things have changed dramatically. What used to be a niche market dominated by Intel’s NUC line has exploded into a thriving ecosystem of powerful, compact machines that punch well above their size. And right at the top of that conversation sits the Minisforum UM890 Pro — a flagship mini PC that has been turning heads since its release and continues to be one of the most talked-about compact desktops heading into 2026.
So what exactly is the Minisforum UM890 Pro, and why does it deserve your attention? In short, it’s a palm-sized powerhouse built around AMD’s Ryzen 9 8945HS processor, wrapped in a premium aluminum chassis, and loaded with connectivity options that rival many full-sized desktop systems. Whether you’re a developer, a content creator, a casual gamer, or just someone who wants a clean and capable desktop without the bulk, the UM890 Pro makes a compelling case for itself at every turn.
This review will walk you through everything you need to know — from the hardware specs and real-world performance to cooling, gaming, benchmarks, pricing, and how it stacks up against the legendary Intel NUC. Let’s dig in.
Design and Build Quality Minisforum UM890 Pro
First impressions matter, and the Minisforum UM890 Pro does not disappoint when you take it out of the box. The UM890 Pro maintains Minisforum’s understated and professional style, with a brushed aluminum chassis that helps dissipate heat and gives a premium feel to the touch.
The mini PC exterior measures 127 x 130 x 67 mm (5.0 x 5.1 x 2.6 inches). If you’re familiar with other mini PCs, one of the first things you’ll notice is that it’s a bit taller than most NUC-like models. But that extra height isn’t wasted space — it’s what allows Minisforum to pack in a more sophisticated cooling system and a richer port selection.
The mini PC consists of a black aluminum case with a detachable plastic top and a plastic bottom. The left and right sides both have large grills to allow airflow. This design choice is deliberate — proper airflow management means the system stays cool even when pushed hard.
One particularly thoughtful detail is the way you access the internals. You can access the storage and memory by removing the top panel, which is held in place by magnets. The magnets are strong and require you to lift the top off with some force, either using your fingernails or a tool like a guitar pick. It’s a clean solution that avoids the typical screwdriver-only approach seen in many competitors.
The UM890 Pro is compact in size, supports wall mounting, and offers various placement options, effectively saving space and enhancing portability. Whether you mount it behind a monitor with the included VESA plate or set it on your desk, it fits neatly into any workspace. In terms of the Minisforum mini PC 2026 lineup, the UM890 Pro sits firmly at the premium end — it looks serious, feels solid, and gives you the sense that real engineering went into every millimeter of its compact frame.

These numbers place the UM890 Pro firmly ahead of Intel-based mini PCs in the same price category, particularly when it comes to graphics and sustained multi-core workloads. The Radeon 780M integrated GPU is among the most capable iGPUs available in any mini PC today, and the gap between it and Intel’s Iris Xe graphics is wide and consistent across every test.
Minisforum UM890 Pro Gaming Capabilities
Let’s be straightforward — the Minisforum UM890 Pro gaming experience is not going to replace a dedicated gaming rig with a discrete GPU. But for what it is, the integrated Radeon 780M does a genuinely solid job, especially in esports and well-optimized AAA titles.
The Radeon 780M GPU handles 1080p gaming comfortably — titles like CS:GO run at around 120 fps and GTA V runs at approximately 60 fps on Medium settings. Those are very playable frame rates for competitive titles and open-world games. The Radeon 780M has a peak GPU frequency of 2800 MHz, offering excellent integrated graphics performance for multitasking and gaming needs alongside AI-assisted features.
Where things get genuinely exciting is the OCuLink port. Minisforum redesigned the UM890 Pro to include an OCuLink interface, which allows you to connect an external GPU enclosure directly via PCIe 4.0 x4. This means if you want to turn your UM890 Pro into a more serious gaming machine, you can attach an eGPU and enjoy a massive performance leap — without sacrificing the compact form factor of the system itself.
The OCuLink interface supports high-speed data connection and transmission, aiding in boosting system performance and expanding device functionality, unleashing the full potential of the mini PC for faster data access and gaming performance. For casual and esports gamers, the UM890 Pro is a great all-in-one solution right out of the box. For those who want more horsepower, the OCuLink upgrade path makes this one of the most future-proof mini PCs in its class.
Cooling System Analysis
Cooling is where many mini PCs fall apart — cramped chassis lead to thermal throttling, loud fans, and shorter hardware lifespan. Minisforum clearly put serious engineering thought into the Minisforum UM890 Pro cooling solution, and the results speak for themselves.
The UM890 Pro is equipped with an active DDR and SSD cooler that reduces DDR temperature by 60% and SSD temperature by 40% compared to passive solutions. It features a new improved 6 cm fan designed for longer operational life and lower noise levels. With a TDP of up to 70W in performance mode, the noise level reaches only 43 dB — 5 dB quieter than the previous generation of Minisforum products.
Beyond the CPU cooling, the system includes a separate fan and dedicated heat sink positioned to keep the PCIe Gen 4.0 NVMe drives in the two M.2 slots cool, as well as a dedicated heat sink for the DDR5 memory modules. This kind of holistic thermal management — covering not just the CPU but also storage and RAM — is rarely seen in a mini PC at this price point.
The advanced cooling system allows the UM890 Pro to run more quietly than many other mini PCs powered by AMD Ryzen 8040 series processors. In practice, it’s nearly silent even under heavy load, with the fan noise only becoming noticeable if you get very close to the machine.
It’s worth noting that Performance mode in the BIOS increases the TDP ceiling to 70 watts. This does increase noise emissions noticeably. The factory Balanced settings offer a very good equilibrium between performance and acoustics, and for most users — those working in home offices, studios, or living rooms — the default mode is the right choice. You get strong performance without any distracting fan noise in the background.
Ryzen 9 Power Explained
The heart of the Minisforum UM890 Pro is the AMD Ryzen 9 8945HS, and understanding what makes this chip special goes a long way toward explaining why this mini PC stands out from the crowd.
The Ryzen 9 8945HS is built on AMD’s Zen 4 architecture with 8 cores and 16 threads, reaching a maximum boost clock of 5.2 GHz. It integrates the AMD Radeon 780M graphics unit with a peak frequency of 2800 MHz — making it one of the most capable APUs AMD has ever produced for compact systems. The chip is part of AMD’s Hawk Point generation, representing AMD’s focused push into ultra-efficient, high-core-count processors designed specifically for laptops and mini PCs.
AMD’s strategy with the 8945HS is clear: more cores, more speed, less heat, and better value. The Zen 4 architecture delivers improved instructions-per-clock efficiency over previous generations, and DDR5 support unlocks significantly higher memory bandwidth — a key factor in integrated GPU performance since the Radeon 780M shares system memory.
The processor operates at 65 watts during short burst loads, settling to a sustained 54 watts in long-term workloads. This power envelope is ideal for a compact chassis — the chip is efficient enough to avoid thermal runaway in a small case, yet powerful enough to match or beat many higher-power desktop-class chips in real-world sustained workloads. In single-core tasks like web browsing, office applications, and code compilation, the 5.2 GHz boost clock ensures snappy, responsive performance. In multi-core tasks like video rendering, compression, and virtual machine operation, the 8-core configuration handles everything with headroom to spare.
Compared to Intel alternatives at similar price points, the 8945HS consistently delivers better multi-threaded performance and dramatically superior integrated graphics. The gap between the Radeon 780M and Intel’s Iris Xe graphics is significant in gaming and GPU-accelerated workloads — a difference that matters greatly to users who want the best possible integrated graphics experience without adding a discrete card.
Minisforum UM890 Pro Price and Value
When it comes to the Minisforum UM890 Pro price, the picture is clear: this is a premium product that is priced competitively for what it delivers.
The barebones model starts at approximately $479, which includes the chassis and processor but no RAM, storage, or operating system. The most popular configuration with 32 GB of DDR5 RAM and a 1 TB PCIe 4.0 NVMe SSD is priced at around $649 to $650 and includes Windows 11 Pro. A top-tier option with 64 GB of RAM and 1 TB SSD is available for approximately $729, also with Windows 11 Pro included.
| Configuration | Price (USD) | Included |
|---|---|---|
| Barebones | ~$479 | No RAM, No SSD, No OS |
| 32 GB RAM + 1 TB SSD | ~$649–$650 | Windows 11 Pro included |
| 64 GB RAM + 1 TB SSD | ~$729 | Windows 11 Pro included |
For context, a comparably specced laptop powered by the same Ryzen 9 8945HS would typically cost anywhere from $900 to $1,200 or more. Getting that processor alongside DDR5 RAM, fast NVMe storage, and Windows 11 Pro in a desktop form factor for $649 represents genuinely excellent value. The barebones option is particularly attractive for users who already have compatible RAM and storage from a previous build.
The UM890 Pro is an ideal choice for professionals who work with video editing, 3D modeling, or virtualization, as well as players looking for a compact system with eGPU expansion possibilities, and users who want a quiet, powerful, and modern workstation. For basic everyday computing tasks, there are cheaper alternatives available — but for users who need real sustained performance, the UM890 Pro justifies every dollar of its asking price.
Comparison with Intel NUC
The Minisforum UM890 Pro vs Intel NUC debate is one of the most common questions potential buyers ask. Let’s settle it clearly and fairly.
Intel created the mini PC category with its NUC line back in 2013, establishing a roadmap that other manufacturers followed for years. The original NUC format used Ultra Compact Form Factor motherboards measuring 100 x 100 mm, housed in a chassis of approximately 117 x 112 x 39 mm. That compact form factor became iconic. Today, the NUC brand continues under Asus — with high-end products like the ROG NUC — but the philosophy of premium engineering at a premium price remains the same.
Intel NUCs have always been respected for their build quality, precision-fit components, and broad software compatibility. However, they come with real trade-offs. A comparable NUC typically costs 30 to 50% more than an equivalent Minisforum model. For most users, that price premium is very difficult to justify when the performance and features comparison does not favor Intel. Most NUC models also offer minimal internal expansion — you typically get one RAM configuration and one NVMe slot. And of course, Intel does not produce AMD-based NUCs, meaning users who want AMD’s superior integrated GPU performance must look elsewhere.
Minisforum occupies a compelling middle ground — more enthusiast-focused than budget brands, with richer expansion options, a more active community, and consistently innovative designs, all priced well below the NUC tier. The UM890 Pro specifically is the only mainstream mini PC in its class offering two NVMe slots, dedicated DDR and SSD thermal management, USB4 with 100W power delivery, dual 2.5G Ethernet, and OCuLink eGPU support simultaneously.
| Feature | Minisforum UM890 Pro | Intel NUC 13 Pro (i7-1360P) |
|---|---|---|
| CPU Architecture | AMD Zen 4 — Ryzen 9 8945HS | Intel Raptor Lake — i7-1360P |
| CPU Cores / Threads | 8 cores / 16 threads | 12 cores / 16 threads |
| Max Boost Clock | 5.2 GHz | 5.0 GHz |
| Integrated GPU | Radeon 780M — 12 CUs, 2800 MHz | Intel Iris Xe — 96 EUs |
| RAM Type | DDR5 5600 MHz, up to 96 GB | DDR4 / DDR5, up to 64 GB |
| NVMe Slots | 2x M.2 PCIe 4.0 | 1x M.2 PCIe 4.0 |
| USB4 Ports | 2x USB4 — 40 Gbps, 100W PD | 1x Thunderbolt 4 |
| Ethernet | Dual 2.5G RJ45 | Single 1G RJ45 |
| eGPU Support | OCuLink PCIe 4.0 x4 | Not available |
| Display Outputs | Up to 4 screens — 8K capable | Up to 3 screens |
| Wi-Fi | Wi-Fi 6E + Bluetooth 5.3 | Wi-Fi 6E + Bluetooth 5.3 |
| Starting Price | ~$479 barebones / ~$649 configured | ~$700+ configured |
| GPU Gaming Score (3DMark) | 3,395 | ~1,500 |
| Active Enthusiast Community | Yes — forums, BIOS mods, tweaks | Limited post-Intel transition |
The verdict here is straightforward. If raw performance per dollar is your primary goal, the UM890 Pro wins decisively. It delivers a more powerful integrated GPU, more NVMe slots, dual Ethernet, broader RAM support, eGPU expansion through OCuLink, and a lower starting price — all in a single package. The Intel NUC legacy carries genuine quality expectations, but it simply cannot match what Minisforum delivers at this price point in 2026.
For users who specifically need Intel platform compatibility — certain enterprise software environments, Thunderbolt 4 certification requirements, or specific DRM workflows — the NUC remains a valid consideration. But for the vast majority of home users, developers, content creators, and creative professionals, the UM890 Pro offers dramatically more value, more expandability, and more raw performance per dollar than any comparable NUC-style system on the market.
Final Verdict
The Minisforum UM890 Pro is not trying to be everything to everyone. It’s trying to be the best possible compact desktop for users who need real, sustained power in a small, quiet, well-connected package. And by nearly every measure, it succeeds.
You get AMD’s Ryzen 9 8945HS with Zen 4 architecture and the powerful Radeon 780M integrated GPU. You get DDR5 memory that scales to 96 GB, dual NVMe storage slots running at PCIe 4.0 speeds, dual 2.5G Ethernet, two full-featured USB4 ports with 100W power delivery, Wi-Fi 6E, Bluetooth 5.3, and an OCuLink port for external GPU expansion. The cooling system — with dedicated thermal management for the CPU, DDR5 memory, and both NVMe drives — keeps everything running quietly and stably. The build quality is premium. And the price, starting at $479 barebones and $649 fully configured with Windows 11 Pro, is genuinely competitive for everything on offer.
Outstanding performance, dual PCIe 4.0 SSDs, 5600 MHz DDR5 RAM, and excellent connectivity make the UM890 Pro one of the strongest value propositions in the entire mini PC market today. Is it perfect? No machine is. In performance mode it gets louder than some users prefer, it lacks a dedicated GPU out of the box, and users with very specific Intel platform requirements may need to look at other options. But for the target audience — power users, developers, content creators, and anyone who wants desktop-class performance in a compact, quiet, and highly capable machine — the Minisforum UM890 Pro is one of the best choices available in 2026. It earns a strong recommendation without reservation.
