It made me wonder: what if I plugged this card into a handheld gaming PC instead? So I did, and let me tell you: itâs a wonder to behold. Itâs enough to make me believe in a rich future where handhelds get more powerful when you dock them at home.
I started with the same $1,999 RTX 5090 FE and 1000-watt power supply from my desktop test, dropping them both onto a $99 Minisforum DEG1. Itâs an open-air external GPU that can connect to the Oculink port thatâs now shipping in a handful of portable gaming PCs, so long as you bring your own desktop GPU and power supply.
