INYUDA Mini PC U9 285H: Strengths & Caveats
✔ Advantages
- 16-core Intel Core Ultra 9 285H processor boosting up to 5.4 GHz with integrated Arc 140T graphics
- Extensive memory expansion supporting dual DDR5 SO-DIMMs up to 7200MHz and 128GB capacity
- Cutting-edge 8K display capability via DisplayPort 2.1 alongside HDMI 2.1 and USB-C video output
- Dual internal storage layout accommodating both M.2 2280 NVMe and 2.5-inch SATA drives
✖ Documented Caveats
- Limited to standard Gigabit Ethernet (Realtek RTL8111H) rather than faster 2.5GbE
- No bundled Wi-Fi or Bluetooth adapter, requiring a user-supplied M.2 2230 E-Key module
GMKtec M6 Ultra: Strengths & Caveats
✔ Advantages
- High-performance 6-core Zen 4 Ryzen 5 7640HS with RDNA 3 Radeon 760M and AV1 hardware decoding
