So what I'm hoping to clear up, is the specific situations in which Davinci CAN take advantage of having eGPUs plugged in.
Now the various eGPU tests and benchmarks from the past few years that I've pored over, have presented a whole range of issues, many of which have now been addressed (driver optimisations/general compatibilities etc.) and with the genuinely powerful internal GPUs found in these two models, it appears that for a lot processing situations, the bandwidth limitations of TB3 will actually slow down performance when you incorporate an eGPU, rather than speed things up. The inability to reasonably upgrade RAM in an iMac Pro at a sensible price rules it out for me (the cost would end up equivalent to a Mac Pro), so the two options I'm considering are: I'm pondering an upgrade to an "enthusiast" class Mac for work in Davinci at the moment (due to the extremely high costs of the Mac Pro 7,1) and I have a few questions about the benefits (specifically for Resolve) posed by eGPUs at this stage of the game (August 2020).
