Back in January, Sonnet announced updated versions of its eGPU Breakaway Pucks, offering new options equipped with Radeon RX 5500 XT and RX 5700 graphics processors for Intel-based Macs. The docks connect to a host Mac over Thunderbolt 3 and allow for more powerful graphics capabilities than the included graphics in many Macs while also providing some dock capabilities such as additional USB ports and display connections.

I've been testing out both versions of the Breakaway Puck for a few weeks now, and I've found that they do offer significantly better graphics performance, particularly if you're using an older machine like the 2016 15-inch MacBook Pro with Radeon Pro 450 graphics that I use as my main machine.
