Pack along an RX 570 with a Sonnet Tech eGFX Breakaway Puck
 

Once upon a time, it was fairly common for laptops to have unique docking stations that added capabilities like multimedia or networking functions. Those days are mostly past, but in recent years we've seen the emergence of external GPU boxes. Like the docking stations of yore, these self-powered boxes are large, heavy, and intended to occupy a permanent spot on a desk. There's no reason you couldn't bring along a Sonnet Technologies eGFX Breakaway Puck, though. These little boxes pack a Radeon RX 560 or RX 570 into a one-liter package.
