It's quiet, it's cool, and it's not upgradeable. Is the eGPU the future of Mac graphics? Apple wants you to think so, and, for the first time, it has worked with an outside firm (Blackmagic Design) to produce a sanctioned eGPU solution for the Mac. Simply titled the Blackmagic Design eGPU, it's available for $699 exclusively through the Apple Store.

It includes a Radeon Pro 580 GPU with 8GB of GDDR5 memory, two Thunderbolt 3 ports, four USB-3 ports, and one HDMI 2.0 port—and it's only compatible with Macs with Thunderbolt 3 ports. When Apple first mentioned this product, it claimed that it's easier to set up, quieter, and smaller than most existing external GPU enclosures.
