16 inch MacBook Pro with eGPU
@eightarmedpet The RX Vega 56 eGPU performs better than the Radeon Pro 5500M dGPU. In my build with the 2019 16″ MacBook Pro, I tested the RP 5500M dGPU vs different eGPUs (RX 580, RX Vega 56, RX 5700 XT, and Radeon VII). Of those four eGPUs, the RX 580 through Thunderbolt 3 is not worth it for a 5500M MBP.
Thats some pretty extensive testing! Cheers for sharing (as ever).
I'm really torn what to do atm, dont think 570/580 level would do me so would prob still need an eGPU, I'm actually swinging back towards the mini after some head scratching...
Just installed bootcamp on mine. First potential stumbling block for AMD egpu usage may be that the Radeon Pro 5500M drivers are the actual Radeon Pro versions this time, its been a bit since I used an AMD equipped mac in bootcamp but I remember the drivers being proprietary versions of the non-pro Adrenalin drivers. May need to wait for bootcampdrivers.com to come out with compatible gaming series drivers. At any rate I installed the latest 1909 build with no issues so I don't expect my Radeon VII to work without error 12, gunning for the RTX 2080 for the time being.
Any insights on a working build? I installed 1909 but it was giving me Error 12 on my eGPU (RX580) and Error 43 on my Radeon Pro 5500M
I wiped it out and am downloading a 1903.30 ISO now and just crossing my fingers...
Were you suggesting I'd actually do better to ignore eGPU and just use the 5500M? This would be for gaming. The eGPU itself works great under macOS.
death to self
@ningauble77 Thank you for letting us know. I installed it tonight and got the RX 5700 XT eGPU working in Boot Camp. As you mentioned, the Radeon Pro 5500M needs Pro/blue drivers. The current Gaming/red drivers on Bootcampdrivers.com do not work for the dGPU. That means no internal display acceleration through eGPU. The internal display itself remains working at slower refresh rate, seems about 30Hz to my eyes.
@haoshiro I have only used Windows 10 1903 V1 ISO. The safe OS versions are 18362.30 to .295. You’d also need to uninstall the stock Boot Camp drivers for the Radeon Pro dGPU first to avoid driver conflicts and stuck internal display when eGPU is connected at boot.
Ok I'm up and running with 16" MacBook Pro i9 model, with an RTX 2080 FE in my Razer Core X, and a disabled Radeon VII in a Razer Core v2 with all my periperals I share between MacOS and Windows connected to the Core v2.
Booting with the RTX card attached causes a boot screen hang, so I do not keep it plugged in.
I hotplugged the RTX/Chroma, windows installed its own drivers and the display came to life within a few minutes.
I then installed the DCH 441.20 drivers I had downloaded from nvidia.
I then plugged in the Core v2/RVII/Mouse+Keyboard+ethernet+storage devices.
Windows update installed AMD drivers for RVII, the internal screen went dark.
I went into device manager, disabled Radeon VII
Went into the 5500M entry, rolled back drivers to the Apple provided ones.
Display was still dark, but rebooted with nothing attached and internal display came up fine with Radeon Pro Control panel etc.
Will follow with some benches, but have to run out for a few.
