- CPU
- 8 cores / 16 threads (Zen 4), Radeon 780M 12 CU
- Memory
- 32 GB
- GPU memory
- 16 GBNo AMD Variable Graphics Memory on this chip (AMD introduced it with the Ryzen AI 300 series). Windows' documented limit for system memory used by graphics (Microsoft, 'Calculating Graphics Memory') is MIN(80% of RAM, MAX(RAM - 16 GB, 50% of RAM)) = 16 GB on 32 GB of RAM. No BIOS UMA maximum for this box was found, so the Windows figure is used. Tuned Linux GTT is not used: a GMKtec NucBox K8 Plus (same Radeon 780M) with 64 GB ran a 26B model with amdgpu.gttsize=49152 (48 GB) and ttm.pages_limit=12582912 (blog.pastwind.org).

Notes
Same 0.83 L chassis and Radeon 780M as the UM880 Plus with a slightly slower 8745H and no NPU; replaceable DDR5-5600 makes 32 GB cheap, but it is a small-model box at about 90 GB/s.
No review of the UM870 Plus was found (searches returned retailer listings only). Dimensions and ports are the shared Minisforum page table (UM760 Plus column; see UM880 Plus dnote). The 8745H has no XDNA NPU according to a WhatPSU snippet on the UM870 Slim (same chip), read only as a search excerpt, so the NPU figure is blank rather than 0. Release month not read. Memory speed source: Minisforum page: dual DDR5 channels up to 5600 MHz: 89.6 GB/s.
