Unboxing: Sonnet eGFX Breakaway Puck

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?

Aye, pretty shocking Design wise… I bought the 350w version so can only go up to a 580 if I get another AMD card… would love otl get a Vega 56 but think they draw too much power? Annoyingly a lot of the error 12 fixes have made more sense to me since I have sold the card I had that had the issue (570!). That makes total sense. I hear what you are saying about swappability, I’m on my 4th GPU in as many months (testing/upgrading) but for me the size of most enclosures is a real issue. I… Read more »

I am slightly disappointed. I liked the slim format of the Acer Graphics Dock (and hopefully the upcoming Lenovo dock) much better. This is easy to transport but not exact use-in-a-coffee-shop sized.

Not sure if you are still under NDA, but as always some pictures of the box internal, pcb, components are always welcome!

I’m taking it apart this weekend for the full review. 😀

Nice, thanks you!

If the card is a standard MXM module, and the cooler is reasonably easy to remove/reinstall, then upgrading to a different card should be doable. Of course, finding MXM cards is not trivial, but not impossible, especially if you do not need the latest/greatest. Looking forward to the disassembly.

All MXM performance  is far away than the standard PCIe. Due to the 2 phase power design, Max will be about 150W or even lower. Enjoy the size but dont expect to have a similar standard NV 1050 performance… Base on my experience, logic should be like this:… Read more »

Looks like a standard MXM-A card. That is good. It also looks like a MXM-B should also fit, which is how I guess they plan to get a RX570 class card in there. Overall, this is a very nifty device. Do we have any idea about what the pricing on this is going to be?

Thanks you for the pictures.
Really good looking thunder board, packing, kudo to Sonet and AMD.
I would have liked Sonet extended the thermal pad, cold plate on the TB controller, even if on half of it to make contact with the heatsink, would have been a must!
I think it’s using the newly released AMD E9xxx polaris series boards: https://translate.google.fr/translate?hl=it?sl=auto&tl=en&u=http%3A//www.xfastest.com/thread-201037-1-1.html
Nice piece of hardware!

Super neat idea from the folks at Sonnet Technology! This is a really elegant way to handle multi-monitor systems using existing technology. I hadn’t heard of the MXM format before this, and now I can’t help but marvel at the space-savings that something like Sonnet’s Breakaway Puck could offer ultrabooks if the idea catches on.

Question from the peanut gallery: How does the noise compare to that of a MacBook Pro 13″ or an Aorus Gaming Box?

Not working for me with ASUS Radeon RX 580 ROG STRIX. I’m unable to understand what the issue is. Changed the PSU from 350 to 600 as well but nothing happening. My MacBook Pro 2017 (MacOS High Sierra) crashes as soon as I connect the eGPU to it. Anyone here can suggest me any solution?
