Minisforum UM790 Pro
The Ryzen 9 7940HS processor and Radeon 780M integrated graphics deliver strong CPU compute in a compact 1.38kg chassis with dual HDMI 2.1 and USB4 connectivity. Its 32GB of fast DDR5 RAM and a 1TB NVMe SSD provide a ready-to-go, high-bandwidth foundation for multitasking right out of the box. This mini PC is best for developers and workstation users who need a space-efficient, quiet node for compiling code or running virtual machines.
Snapshot
The 30-Second Version
The UM790 Pro's Ryzen 9 7940HS CPU is faster than two-thirds of desktops we test, making it a solid productivity workhorse, but its integrated graphics turn in a dismal 11.3/100 gaming score. 32GB of RAM and generous ports are highlights, while reliability sits in the bottom 12%. It's worth a look if you value tiny size and quiet operation over raw power.
Pros & Cons
Pros
- Ryzen 9 7940HS CPU handles development and office tasks with ease, tops 66% of desktops 87th
- 32GB of DDR5-5600 RAM outclasses most desktops in this price tier 83rd
- Port selection is above average with USB4, dual HDMI 2.1, and 2.5Gb Ethernet 74th
- 1TB NVMe SSD delivers fast loads and plenty of space 71st
- Whisper-quiet operation even under full load
Cons
- Reliability sits in the bottom 12%, a major durability concern
- Integrated Radeon 780M GPU is bottom-tier, with a 11.3/100 gaming score
- No dedicated GPU upgrade path locks you out of gaming and graphics work
- Price spread is huge; high MSRP pushes it into gaming desktop territory
- Weight and dimensions unknown, but it's not pocket-sized
The proof
Performance
Under the hood, the Ryzen 9 7940HS runs at a base 4.0 GHz with 8 cores and 16 threads. In our testing, it's faster than two-thirds of all desktops we've benchmarked, chewing through compile jobs and large spreadsheets without breaking a sweat. The 32GB of DDR5-5600 RAM is well above average, so you won't run out of memory even with a dozen browser tabs and a couple of VMs going.
Graphics are integrated, which is where this machine stumbles. The Radeon 780M is a weak link, turning in a gaming score of just 11.3 out of 100. Don't expect to game on it beyond indie titles or older games at low settings. But for day-to-day visuals, it drives up to two 4K displays over HDMI 2.1 without issue. Connectivity is generous with USB4, dual USB-C, quad USB-A, and 2.5Gb Ethernet, more than enough for most setups.

vs Competition
Stacked against tower desktops like the Lenovo Legion Tower 5i or MSI Aegis RS2 AI, the UM790 Pro gets absolutely steamrolled in gaming, our numbers rank it among the bottom 11% of systems while those towers typically land above the 70th. But it's a fraction of the size and power consumption. The Dell XPS EBT2250 often costs more for similar CPU performance but includes a dedicated GPU, so if you never game, the Minisforum undercuts it. The HP OmniDesk M03-0074 is perhaps the closest competitor in the mini PC space, but its CPU options tend to lag behind this Ryzen 9. If you're picking a tiny productivity box, the UM790 Pro is a strong spec leader, just don't compare it to full-fat gaming rigs.

Price
Value & Pricing
Prices range by $276 across vendors, so you'll want to shop around. The $769 low end is a decent value for the specs, especially if you need a compact, silent workhorse. At $1045, you're deep into entry-level gaming desktop territory that would crush this machine's GPU performance. For developer-centric tasks, the CPU and RAM combo shines at the low end, but when the price climbs, the value proposition gets shaky fast.

Overview
The Minisforum UM790 Pro packs a Ryzen 9 7940HS and 32GB of DDR5 into a tiny box. That CPU lands in the 66th percentile among all desktops we track, not chart-topping, but no slouch for productivity. For developers and home office users, it's a capable machine that barely whispers under load. The catch? Reliability and gaming are serious low points, with reliability sitting near the bottom of our database. If raw performance per dollar is your focus, there's a lot to like, but you'll want to weigh the trade-offs carefully.
Our scoring tells a clear story: 66.5/100 for development, 65/100 for home office, and an overall of 60.9/100, dragged down hard by an 11.3/100 gaming score. That Radeon 780M iGPU is fine for video playback but chokes on modern games. For a mini PC that sips power and stays quiet, though, it's a tempting proposition, especially with prices ranging from $769 to $1045 depending on where you shop.
Common Questions
Q: Can this mini PC handle 4K video editing?
The CPU is capable, it lands in the top two-thirds of our benchmarks for raw processing power, but the integrated Radeon 780M GPU struggles with rendering and effects. Light edits are fine, but for heavy workloads you'll want a system with a dedicated graphics card.
Q: How many monitors can I connect?
It supports up to two 4K displays via the twin HDMI 2.1 ports, and you can add a third through the USB4 port with an adapter, though we'd recommend sticking to two for smooth performance.
Q: Is the RAM upgradeable?
Yes, the UM790 Pro uses standard DDR5 SODIMM slots, so you can swap out the 32GB for up to 64GB if needed, but keep in mind the reliability concerns flagged in our testing.
Who Should Skip This
Gamers and anyone needing GPU horsepower should skip this machine without a second thought; the 11.3/100 gaming score is a dealbreaker. Also, reliability ranks in the bottom 12%, so if you depend on your PC for critical work without downtime, this isn't the safest bet. Budget buyers who can use a larger tower will find better price-to-performance elsewhere.
Verdict
If you need a tiny, silent productivity machine with a fast 8-core CPU and tons of RAM, the Minisforum UM790 Pro is a strong contender, especially if you can grab it near the $769 mark. Our database flags reliability as a serious concern, though, so factor in a backup plan. For any gaming or GPU-accelerated work, look elsewhere. It's a specialized tool that nails its niche but stumbles outside it.
