You may not have heard about Sonnet Breakaway Puck. It's the first macOS compatible handheld eGPU enclosure with an MXM graphics card, and I've been looking forward to checking it out in person. I was fortunate enough to receive one of the first production units for an eGPU.io review. My media sample has a Radeon RX 560. Sonnet plans to offer one with an RX 570 as well. Here are some unboxing photos and initial impressions.

You notice right away that the entire package is smaller than most eGPU enclosures on the market. Sonnet also sent the optional VESA bracket and .5m DisplayPort cable for mounting the enclosure behind a monitor.

Inside is the Breakaway Puck itself, a 160W power brick, power cable, and .5m Thunderbolt 3 cable.

This thing is small, really small. I set one of the smallest-size GPUs, an R9 285 mini ITX Compact, next to the RX 560 Breakaway Puck for scale.

Here's the rear port layout: 3x DisplayPorts, 1x HDMI, 1x Thunderbolt 3, and DC power port.

The Sonnet logo lights up in Blue when there's connectivity with a host. The 160W power brick is fairly large. I have no complaints though because it keeps the eGPU enclosure size minimal.

The VESA bracket has rubber padding on top to keep the Breakaway Puck snugly in place while preventing scratches during insertion and removal.


Now it's time to plug it in! A special thank you to Goalque for finding a workaround for unsupported AMD cards in High Sierra. It's easier to enable external graphics functionality in 10.13 with the RX 560 than older AMD cards. Goalque is finishing up a GUI installer and will share his High Sierra automate-eGPU solution soon. After logging out then logging back in, About this Mac showed the RX 560 Breakaway Puck as R9 XXX. It worked with an external monitor as expected.

The enclosure Thunderbolt firmware is version 25.1. Power Delivery is set at 45W.

Here's a quick comparison of Luxmark results between the iGPU, dGPU, and eGPU.

Testing and a full review of this Sonnet eGFX Breakaway Puck RX 560 are under way. In the meantime, please let me know if you have any questions I can answer right away.

Awesome First Impression review.
Could you please do a benchmark with a Game that requires massive power of CPU+GPU together Like Civilization 6 or XCOM 2 with 13" MacBook Pro?
I believe it will be a good way to test any EGPU and give a clear idea to all the gamers like me.
Thank you and please keep making more reviews

Can you please do a side-by-side comparison with Gigabyte AORUS Gaming Box? Thanks!

This is amazing! And just as I bought the larger Sonnet... damn in!
Will have to see if Apple brings a small enclosure option to the table this spring before my next purchase.

Which Sonnet box did you get - 350W or 550W?
