System specs:

Late 2016 15″ MacBook Pro – i7-6700HQ/Radeon Pro 450 dGPU/HD Graphics 530 iGPU/16GB RAM/256GB SSD

 

eGPU hardware:

Razer Core V2 + Radeon RX Vega 56 + .5m Thunderbolt 3 cable

 

Hardware pictures:

 

Installation steps:

macOS 10.13.2 – It was plug and play so nothing to report here.

Windows 10 1709 – I performed the same procedure as detailed in my Boot Camp setup guide. With the latest W10 Fall Creator Update, only PCI Express X16 Controller – 1901 to the dGPU needs to be disabled in order to resolve error 12. This is an improvement over older W10 versions which required both PCIe bridges to dGPU and left Thunderbolt 3 ports disabled for AMD eGPU to work.

 

Benchmarks:

I ran AIDA64 with nothing attached to the expansion ports to get a baseline of bandwidth (left). I ran ATTO benchmark on an USB SSD attached to the USB port of the Razer Core V2 then ran AIDA64 at the same time (right). You can see they are sharing bandwidth through a single Thunderbolt 3 cable.

 

Here are some benchmark numbers for this eGPU setup. They were run in internal display (left) and external monitor (right).

 

Comments:

I use this eGPU with my 15″ MBP in internal display mode only. It’s been very reliable booting up with rEFInd. The dGPU remains disabled and iGPU attached to the internal display even when I boot it up without eGPU connected. If you experiencing flickering issues when there’s no power source connected to the laptop, change the Intel Graphics setting to not use power saving.

Radeon drivers in Windows are getting better for external graphics use. With this pairing, I see very minimal loss using the internal display vs. external monitor. If you plan on using an AMD eGPU with an external monitor on a TB3 15″ MBP, instead of disabling the PCIe 1901 – Radeon dGPU, try disabling PCIe Controller 1905 – left TB3 ports instead. This means you’ll only able to use the right TB3 ports for eGPU and other peripherals. What you’ll gain is ease of switching between macOS and Windows.

Have you used this setup in MacOS? Any benchmarks?

Unfortunately I didn’t have time to run benchmarks in macOS prior to sending the media sample back to Razer.
