According to a Valve Engineer, the Steam Machine specs outclass the most common PC configurations. The company relied on its own hardware surveys to choose the system’s components. Even as an entry-level option, Valve claims that 4K/60 fps performance is realistic, despite a memory-limited GPU.

Ironically, they seemed to figure ‘low end’ is where the sales are at. Yet my guess is most ‘low end’ buyers pick Nvidia by default, and folks who are upgrading from anything aim higher than a B580.
I would’ve killed for a 512-bit Arc card (other than the unobtanium datacenter GPUs), but that’s a fever dream for now…
