Sonnet eGPU Breakaway Puck RX 5700 - Key specifications Instead of an enclosure large enough to hold some small Windows PCs, the Breakaway Puck is small enough to be hidden on a desk or behind a monitor using a VESA mount, taking up as little room as possible while still providing the same power. The Sonnet eGPU Breakaway Puck RX 5700 tries to take on the problem by packing all the main functionality of an eGPU enclosure into a compact device. Given the designs of some models, they can also stick out like a sore thumb, as a permanent and unmistakable reminder that you wanted more GPU performance than the Mac could provide on its own.
The PCI-e eGPU enclosures still have one big issue - they are hefty boxes that sit on or near your desk, taking up a lot of desk space, and they perform best with an external monitor, instead of looping back to a MacBook Pro's internal display. It's cost-effective and could potentially result in a higher-performing Mac than Apple could provide for the same price. The eGPU enclosure is a great way to increase the performance of your existing Mac or MacBook without paying to upgrade the unit for a newer model.
The Sonnet Breakaway Puck is very tightly packed, with a fan in the top (iPhone 11 Pro for scale)
