UM870 Slim vs AI X1 Specs
Processor
Both mini PCs use an eight-core, sixteen-thread AMD Ryzen 7 processor with up to 4.9 GHz boost speeds and 16 MB L3 cache. The UM870 Slim features the Ryzen 7 8745H, while the AI X1-255 uses the Ryzen 7 255. Both chips rely on Zen4 architecture for multi-threaded computing. This similarity means general productivity tasks and heavy office work will feel comparable on either machine. You get identical core counts and thread counts, so single-core and multi-core performance benchmarks should remain very close. The choice here depends less on raw CPU power and more on how each model manages that power under load.
Memory
The UM870 Slim ships with 32 GB of DDR5 RAM, whereas the AI X1-255 includes 16 GB. Both systems support DDR5 SODIMM modules, with the AI X1-255 explicitly noting speeds up to 5600 MT/s. The UM870 Slim allows expansion up to 96 GB across its two slots. The AI X1-255 supports up to 64 GB. Starting with 32 GB gives you more headroom for multitasking right out of the box. You will not need to upgrade immediately if you run many applications simultaneously. The AI X1-255 may require a RAM upgrade sooner for heavy workloads. This initial configuration difference impacts your immediate usability and long-term upgrade costs.
Storage
The UM870 Slim includes a 1 TB M.2 2280 PCIe 4.0 SSD. The AI X1-255 comes with a 512 GB SSD of the same interface type. Both units feature dual M.2 slots that support expansion up to 4 TB per drive. The UM870 Slim offers double the starting storage capacity. This is beneficial for storing large files, videos, or multiple operating systems without immediate expansion. The AI X1-255 provides adequate space for standard office use but may fill up faster for media editors. You can upgrade either system later, but the UM870 Slim saves you an initial purchase. The dual-slot design on both ensures future flexibility for large data sets.
Networking
Both systems include a 2.5Gbps LAN port for stable wired connections. Wireless capabilities differ significantly. The UM870 Slim uses Wi-Fi 6E and Bluetooth 5.3. The AI X1-255 upgrades to Wi-Fi 7 and Bluetooth 5.4. Wi-Fi 7 offers higher throughput, lower latency, and better congestion handling than Wi-Fi 6E. This makes the AI X1-255 superior for modern wireless networks and future-proofing. If you rely on high-speed wireless transfers or live in a dense network environment, the newer standard provides a clear advantage. The wired 2.5G port remains identical on both, so Ethernet performance will not vary between the two models.
Compatibility
The AI X1-255 features an OCuLink port, allowing direct connection to external GPUs like the MINISFORUM DEG1 dock. This provides a pathway for significantly enhanced graphics performance for gaming or rendering. The UM870 Slim does not list an OCuLink port. Both units support USB4 for high-speed data and display output. The UM870 Slim supports triple displays via HDMI, USB4, and DisplayPort. The AI X1-255 supports four-screen display setups. The OCuLink port on the AI X1-255 offers unique expansion potential that the UM870 Slim lacks. If you plan to use discrete graphics later, the AI X1-255 is the only viable option.
Which Mini PC Fits Your Needs
Users needing maximum out-of-box RAM and storage
The UM870 Slim arrives with 32GB DDR5 RAM and a 1TB SSD. This configuration handles heavy multitasking and large file storage immediately. You avoid the initial cost and effort of upgrading memory or adding drives later. The dual M.2 slots allow expansion to 4TB total storage, ensuring you have ample space for projects without extra purchases.
Users wanting modern networking and eGPU support
The AI X1-255 includes Wi-Fi 7 and Bluetooth 5.4 for faster wireless connections. It also features an OCuLink port, allowing you to connect an external graphics card for better gaming performance. This model supports four-screen displays and includes built-in microphones and speakers, making it ideal for versatile setups and future hardware additions.
Professionals requiring triple display productivity
The UM870 Slim supports three independent displays via HDMI 2.1, USB4, and DisplayPort 1.4. This setup boosts productivity by expanding your workspace. You can connect an 8K monitor and two additional screens simultaneously. The stable 2.5G LAN connection ensures smooth data transfer, making it a reliable choice for office environments requiring multiple active windows.
