I have a Mac mini Late 2018, Razer Core X, Radeon RX 5700XT, using Big Sur. One monitor, connected through HDMI on the mac and through DP on the Razor. (have to switch input port on the monitor when using the Razor)

Succeeded in getting it to work with Windows10 20H2 (OS Build 19042.631), latest AMD drivers.

I used aa15032261 's automated EFI replacement, and followed his instructions. The TB3 for the Razer is in the leftmost TB3 port now.

There are some peculiar things on start-up. I can't get it to work cold starting the mini and going into boot mode and choosing the bootcamp bootdisk. The modified EFI does start up, and recognizes the RX5700, but Windows still starts with the Intel 630 from the mac-mini (even though I have that disabled in Win10), and the RX5700 doesn't show up in device manager.

It does work when I boot into Big Sur, connect the Razor, then switch the start-up disk to the bootcamp disk, restart and press Spacebar when the automated EFI shows up.

So wanna let you all know that my MacBook Pro 15 2019 is running windows 10 with all updates with my egpu with a sapphire radeon rx 5700 xt nitro+ and the newest driver from bootcamp drivers. Only thing I gotta to is boot to windows with the egpu not connected, the. connect it and restart windows and boom it works perfectly with 2 external 4K display and full driver support and Customization.

Yes, Apple has been busy improving eGPU support in Bootcamp Windows (for Intel Macs).

Thanks for letting everyone know about the 2019 MBP 15” 👍

Hello if anyone could help me that would be great. My build is a late 2016 MacBook Pro with a razer core x and an Amd Radeon RX 580 4 gigs. I’ve been going at it for a week now trying to get the graphics card to work on my windows bootcamp side of things with no luck. Oh I forgot to mention I have windows bootcamp allocated to an external hard drive. So anyways, almost all week long I have been trying to figure out how to get past error 12 and I have not been able to figure it out. The program states that the drivers are installed but there’s an issue with the graphics and I just can’t figure out how to fix it at all. Not to mention every time I leave the egpu connected while windows bootcamp is loading it does the black screen or the stuck windows logo and I don’t know how to get past that either. If anyone has any tips or can send me a video, (I’m a visual learner), or anything to help me that would be amazing. I didn’t think it would be this hard but it’s been nothing but a nightmare. And before anyone asks yes the ports are thunderbolt 3 and yes I’m running off the latest windows update (version 20H2). Please any help would be amazing to get through this.

@Gabe, Which specific model is your 2016 MacBook Pro? Most likely you'd need to do DSDT override in Boot Camp to use an AMD eGPU. Fortunately we have those modified DSDT for the 2016 MBP models that you can use. Look into the build guides with matching components with your laptop and equipment.

Are there extra steps for TB2 MBPs?

@tigerwoods2021, It depends on the particular Mac you have. You'd need at least the Apple Thunderbolt 3 to Thunderbolt adapter. Don't use other brand adapter because we found the Apple adapter to be the most reliable for Thunderbolt detection in Windows.

I know this is quite a bit late, but trying to get an AMD eGPU to run just isn't worth the effort, in my experience. Toss an nVIDIA eGPU into it and you'll be good to go.

Just an FYI, I have a 2018 MacBook Pro connected to a Razer Core with an nVIDIA GTX 1080 Ti in it. I went through countless hours trying to get my AMD Vega 64 to run properly, to no avail. With my current setup:

- Windows recognizes both internal and external GPUs (it prefers to use GTX 980 Ti drivers, but I haven't noticed any issues with performance). I have the Razer Core *and* my monitor connected via different USB-C ports, so the MacBook just farms out video processing to the eGPU while displaying the output to my monitor directly (in other words, I don't have any HDMI/DisplayPort cables connected to my eGPU). I can provide pics if this doesn't make sense. One thing to keep in mind is that the cable for the eGPU has to be on one side of the laptop all by itself; if you try to add other USB-C devices to that same side, it will overload the bus. Put your video output and peripherals into the USB-C ports on the other side of the laptop.

- Mac recognizes the internal GPU, but not the eGPU. Which is just fine for me as I don't really game on the Mac side. The internal GPU does all the video processing and displays the output to my monitor directly. This also allows me to reboot the computer into either Mac or Windows modes seamlessly without having to do anything extra to get the video working.

@Eddie, Nvidia eGPU has always been a better choice in Boot Camp mode than AMD. There are some Macs with iGPU-only that works fairly straight forward with AMD eGPU in Windows, but I agree it's usually a challenge for most Mac users.
