@max-vorotnikov, I tried a Razer Core V2 + Pro W5700 with my 2020 13-in MacBook Pro running Win10 1903 V1 just now. The eGPU worked through hot-plug with the disablement of 3x PCI Express Root Ports. In Device Manager, click View > Devices by Connections, then expand PCI Bus to disable three PCI Express Root Ports below the very top one. This top port is the one closet to TAB key.

@melkorstar, in the end, after many attempts, I could not start any other version of Windows, except 1903 V1

In all other versions of Windows, there is a conflict at the level of the UEFI firmware, which cannot correctly determine the Large Memory sector under the eGPU. Also I tried Windows 11, same results

all versions nVidia drivers are installed correctly, but the external display works through the eGPU only if the Intel Graphics adapter is disabled in the Device Manager

@melkorstar, yes, literally the first cumulative updates, including security updates, immediately break the definition of eGPU. Therefore, you need to severely restrict updates through the Local Policy

Hi!

As I am into BootCamp experiments for some time now, I can confirm that there can be quite some differences between machines. I have just bought myself a fairly seldolmly used 2020 MBPro 4TB i5 / 16 / 512, just the same spec like part of this build. There is certainly a chance to get it to run under Win10 1903 V1 by using the "turn it all off before you install anything" method: https://egpu.io/forums/builds/2020-13-macbook-pro-10th4cg-rx-vega-56-32gbps-tb3-razer-core-x-macos-10-15-4-win10-andygev35/ >> confirmed it last night.

But bl**dy hell is it complicated and determined to fail (you really have to stick to every step, otherwise: happy reinstalling). If you look at my 2018 MBPro 4TB config, I have noticed not a single issue in months now running 21H1, updating like on your daily laptop. The only downside which I quite ignore is that the internal Macbook screen is stuck at Windows' boot up logo - well known and I couldn't care less. Coldplugging is mandatory of course.

On the 2020 MBPro, Code 12 is your friend if you don't use the "tab TB port" while TB support turned off on the other 3 on the MBPro 2020 4TB, at least with my Radeon - an several others - anybody I suppose. To me it looks almost like the 2020 has gone back to old days when 2016 / 2017 MBPros hadn't full throttle on 50% of their TB ports which I quite dislike. I thought I would opt for a slight improvement here, but things did rather go downhill. So I am actually thinking about giving the 2020 MBPro back to my dealer as it just rose problems when there weren't any left. I also noticed that even under MacOS the 2020 has poor USB / TB periphal power supply, as my 2.4G mouse dongle got stuck sometimes under heavy load, just as my external SSD broke down a bit in performance figures. Maybe this helps some of you!

@freezerxt, It is on Apple to optimize the firmware of the 2020 13-in MacBook Pro. It's the only Intel Mac with on-die Thunderbolt controller. My guess is their engineering team was already moving on to M1-series systems by the time the 2020 Ice Lake MBP came out. There's performance advantage to having this integrated Thunderbolt connection but as we all learned, it takes a lot of effort to make it work.

In my opinion your guessing is quite close to actual facts. Therefore I am not too optimistic about Apple updating an, thinking of their total shift to M1 processors, outdated machine. Another thing I noticed about graphics perfomance in comparison is that my Radeon on the 2020 MBP performs badly no matter what I am setting up for graphics. The calculation of images seems to be erratic and not consistent, just like the whole system was "in a haste". Difficult to describe actually, I have never seen such a behavior before. That wouldn't be too bad if gaming hadn't become almost impossible (and I am not talking about shooters, but Settlers, the Stronghold series etc).

To be honest, I am done for the moment with the 2020 MBPro. If there is new success, I will possibly come back to buy one, but today just seems like the wrong time doing so. And as I am happy with my 2018 MBPro I will just go on with my setup, although the original plan was of course to double the RAM and the hard drive space and, of course, to benefit from the direct thunderbolt connection. If I didn't care that much about BootCamp and playing my "back in the days games" on the eGPU, I'd just have gone for the M1, I suppose.

Anyway: I appreciate you did a good nVidia build with the 2020 MBPro!
