“During the development of the Thunderbolt 3 protocol, the ability to seamlessly interface with a GPU in an external PCI-E breakout box was added, rather than it just being a hack,” Mike Wuerthele reports for AppleInsider. “In theory, an external GPU releases the user from the shackles of lower-performing GPUs typically found in a laptop, and allows the user to leverage desktop units in an external enclosure, benefitting from both an improvement in thermal conditions, as well as no limitations on consumed energy.”

“The vaguely Mac Pro styled Razer Core used in this particular project works without flaw, and needs very little configuration in a Mac running Windows under Boot Camp,” Wuerthele reports. “However, the entire external GPU assembly doesn’t work at all in macOS unless you start modifying the operating system itself. Also, the macOS implementation doesn’t feed the video back to the MacBook Pro’s screen, so an external monitor is mandatory.”

“With almost no fiddling or configuration, AppleInsider testing on a Razer Core and Nvidia GTX 980 in macOS managed 4.5 teraflops, with the two-year old Nvidia 770 pulling down 3.1 teraflops,” Wuerthele reports. “The new Nvidia 1080 in Windows 10 delivers around 9 teraflops, with the GTX 1070 pushing 6.5 teraflops. For comparison, the Radeon Pro 460 in the high-end build-to-order 15-inch MacBook Pro manages 1.6 teraflops, and the custom-build Mac Pro with dual AMD FirePro D700 delivers 3.5 teraflops, per GPU.”
