I tend to agree that Intel (x86) based Macs will be current for some time to come... for instance, the Mac Pro runs on professional grade Intel Xeon processors, and I doubt that will be switched to ARM for some time. I don't think Apple will have an A-series chip that can compete in that space for some time (i.e. longer than 24 months). And as long as there is at least one current Mac being sold with with an Intel CPU, there will be x86 versions of macOS released with all the new goodies.My issue is i need virtualization which isn’t happening so fast with arm and x86 clients. I think Apple may continue to offer intel machines for longer than we think. I’m going to pickup a refreshed intel MBP (hopefully with 10th gen i9) whenever they release them - then i’ll wait out the transition and figure things out from there.
Also, I am not really a tech person, but would it be an easy process for an ARM chip to be mated to a dedicated GPU via traditional PCIE connection? All the talk is about Apple SOC's, but even the famed A-series integrated GPU's are not going to replace the likes of the RP 5600M. To say nothing of the Radeon Pro Vega II GPU's available in the Mac Pro (with 32 GIGABYTES of VRAM per card).
