Apple released 10.14.4 Developer Beta 3 [18E194d] today. It's not plug-and-play with AMD Radeon VII just yet. I decided to try an older trick when RX 480 first released, borrowing the personality of a supported card. In this case RX Vega10 was the one to use and it worked. The Radeon VII can now function like a natively supported eGPU in macOS 10.14.4 beta. This same trick should allow it to work inside a Mac Pro tower.

I'm pairing the Radeon VII with the original Razer Core which has the unsupported TI82 USB-C controller. First order of business was to run @mac_editor's Purge-Wrangler to whitelist this TI82 block. Once this is done the Thunderbolt 3 connection was working. Next step was to add the Radeon VII's PCI ID into the appropriate kext to allow the drivers to load. AMDXRadeon5000.kext was the one to inject 0x66AF1002. Run permission repair then restart and it should work.
Here are some benchmarks. Luxmark showed all 60 compute units with strong performance.
Even though the drivers are not finalized, this Radeon VII looks to be a computing beast. Not sure why AMD pushed it as a gaming card. Also it does not seem to suffer from power-related crashes like the RX Vega 64. I've used the Radeon VII with ASUS XG Station Pro and Razer Core and no issues so far.
Great!! I’m quite sure 10.14.4 will officially support it!

This is great! Does the Radeon VII works in bootcamp as an XConnect GPU?
Yes it does, I'm using it with my mac mini 2018, and let me tell you with FFXV running at 3440x1440 vsync on and Max settings (wtihout nvidia tech) it runs between 52-60fps (i have an overclock in the card) but before with my vega 64 it was in 33-42 fps
