Corsair AI Workstation 300 (Ryzen AI Max+ 395, 128GB)

The Corsair AI Workstation 300 is a 4.4-litre aluminium PC on AMD's Ryzen AI Max+ 395 with 128GB of unified memory, a 2-year warranty and 60-day returns. It is for a buyer who wants Strix Halo from a mainstream brand with US support. The one thing to know: unified memory lets it hold large mixture-of-experts models; dense 70B models are slow and there is no CUDA.

What does the Corsair name add over the boutique mini PCs?
