I heard about this bottleneck a lot, but I just haven't noticed it--I do not have thermal issues. I run in clamshell in a cheap vertical lap top stand. I rarely hear the CPU come on when I'm docked with the standard BM eGPU. I run scaled 'looks like' 2560 x 1440. I run tons of apps and browser tabs in multiple spaces. I only notice the CPU is weak when I'm encoding with something that isn't aided by GPU. One case I do hear the fan come on is near the end of a 200+ step unit test in pycharm on my primary personal web app. But that is just about the only time I can think of it comes on and it shuts back down as soon as my tests complete. (hopefully all passing!) A bit more on my specific setup: - 2018 MBA (maxed out) - Dell P2715Q monitor - Blackmagic eGPU - Edifier S880DB (USB HD Audio) - AT2020 USB+ mic - Logitech C920S webcam - Vertical Laptop stand - Magic keyboard / trackpad This setup is probably the best I've ever had, because the portability is great and the docked situation is just very, very good. All those peripherals off a single connection to the laptop. I am hoping that the ARM mac will have much better graphics, but I think it is likely at least the first two generations of it will still be majorly improved even by the 580 in the current blackmagic. It is worth mentioning that I do try to use the software disconnect of the eGPU and have had that just stall out or not complete. I have not tried the trouble shooting someone suggested here though--and it is so stable w the BM that I don't worry about yanking the cable anymore.
