Minisforum UM870 Slim Silver

The Ryzen 7 8745H CPU is a standout in a chassis this small, but the integrated graphics score a brutal 10.5 out of 100. You get 32GB of fast RAM and a 1TB SSD, making it a ready-to-go productivity monster. Just don't expect to play anything more demanding than a 2D indie game, and keep an eye on that 11th percentile reliability rating.

The 8-core, 16-thread Ryzen 7 8745H is the star here, boosting up to 5.0GHz. In our database, this puts it ahead of many bulkier desktops for raw CPU throughput. You're looking at a machine that handles development environments and heavy browser loads without breaking a sweat. The 32GB of DDR5 RAM, sitting in the 73rd percentile, gives you plenty of headroom for VMs and memory-hungry apps. Storage is a 1TB PCIe 4.0 drive, also in the 73rd percentile, so load times are snappy. But the integrated GPU is the bottleneck. It's fine for driving multiple 8K displays via HDMI 2.1 or USB4, but any 3D workload will bring it to its knees. The gaming score of 10.5 out of 100 tells you everything you need to know.

Stacked against the HP Omen 45L or the ASUS ROG GM700TZ, the UM870 Slim isn't even playing the same game. Those towers offer dedicated GPUs that make the Radeon 780M look like a calculator. The Minisforum's CPU is competitive, but the overall performance gap is massive for anyone who games or renders. The Lenovo Legion 34IAS10 is another beast entirely. Where the UM870 wins is size and power efficiency. It sips power and takes up almost no space, while those towers are hulking, power-hungry machines. It's a classic case of picking your priority: raw power or compact efficiency.

At $1079, the UM870 Slim is a bit of a tough sell if you're just looking at raw specs per dollar. You're paying a premium for the tiny form factor and low power draw. A traditional tower at this price, like the HP Omen 45L, will absolutely demolish it in graphics performance. But if your work is purely CPU-bound and desk space is at a premium, the value proposition shifts. The included 32GB of RAM and 1TB SSD sweeten the deal, saving you from immediate upgrades.

The Minisforum UM870 Slim packs a Ryzen 7 8745H and 32GB of DDR5 into a tiny chassis, and for CPU-heavy work, it's a solid little performer. Our benchmarks put its processor in the 67th percentile among all desktops, which means it's comfortably above average for a machine you can hide behind a monitor. The integrated Radeon 780M graphics are a different story, landing in the 11th percentile. So while it chews through compile jobs and office multitasking, don't expect it to run modern games at anything beyond low settings.

Gamers and creative pros should look elsewhere. The GPU score of 10.5 out of 100 is one of the worst we've seen for any modern desktop task involving 3D. If you do any video editing, 3D modeling, or want to play AAA titles, a mini PC with integrated graphics is the wrong tool. The 11th percentile reliability score is also a concern for anyone who needs a machine they can depend on without question. A traditional tower with a dedicated GPU will serve you far better.

The Minisforum UM870 Slim is a niche machine that excels at exactly what it's designed for: being a powerful, tiny workstation for CPU-focused tasks. The CPU and RAM are genuinely impressive for the size, and the connectivity is top-notch. But the abysmal gaming performance and low reliability score are red flags you can't ignore. If you need a silent, space-saving PC for coding or office work and never plan to game, it's a strong contender. For everyone else, a traditional desktop offers far more flexibility and power for the same money.
