Sonnet debuts portable external graphics (eGPU) docks with support for Thunderbolt/USB-C displays — Apple World Today

eGPU systems boost a computer’s graphics performance by connecting a more powerful graphics processor via a Thunderbolt 3 connection and bypassing the computer’s onboard GPU to deliver enhanced graphics performance. Sonnet’s eGPU Breakaway Puck Radeon RX 5500 XT and Radeon RX 5700 systems are designed for professionals who need to run graphics-intensive applications on their Intel-based MacBook Air, MacBook Pro, Mac mini, or iMac with Thunderbolt 3 ports. Currently, M1 Macs don’t support eGPUs.

Both eGPU Breakaway Puck models support up to three 4K @ 60 Hz displays (four with one of Sonnet’s dual-display adapters, sold separately) or one 6K plus two 4K displays at the same time. Through a second Thunderbolt 3 port, the Pucks provide both graphics and data to support all popular Thunderbolt/USB-C displays, including the LG UltraFine 4K and 5K displays sold in the Apple store. 

Both models include two USB Type A ports to enable connection of peripherals — such as a keyboard, mouse, or even a software license authorization key dongle — to the computer without taking up its few onboard ports.
