The Ryzen 5 7640HS in the UM760 is a capable 6-core, 12-thread chip that handles everyday desktop work, browsing, and light multitasking comfortably. The Ryzen 7 8745H in the UM870 steps up to 8 cores and 16 threads with a newer Radeon 780M GPU, and independent benchmarking has shown its multi-core performance landing in the upper third of current mini PCs, without thermal throttling under sustained load.That extra core count and the RDNA 3-based Radeon 780M make the UM870 the meaningfully better pick for anyone doing content creation, code compiling, or casual 1080p gaming — reviewers have measured the 780M hitting 75-123 FPS in popular titles at 1080p, a tier above what the 760M in the UM760 typically manages.Connectivity is another real difference, not just a spec-sheet footnote: the UM870 adds dual 2.5G Ethernet ports and triple display output, compared to the UM760's single display path over HDMI/USB4. If you're setting either of these up as a home server or a multi-monitor workstation, that difference in networking and display support is worth the extra $100 on its own.

And if you plan to run Linux on either, the bundled Wi-Fi cards have had driver support issues reported by some reviewers — a wired Ethernet connection sidesteps that entirely.More mini PC dealsPowered by AMD Ryzen AI 9 HX 370, this Geekom mini PC combines 32GB DDR5 memory, a 1TB SSD, WiFi 7, USB4, 8K output, and 80 TOPS AI performance for demanding workloads.Read our full reviewView DealThe GMKtec K16 mini PC delivers Ryzen 7 7735HS performance with 32GB LPDDR5 RAM and a 1TB SSD.
