eGPUs are kind of a joke. People would be way more likely to use dedicated GPUs with Macs if they had PCIe slots.
The last Mac with good PCIe slots was the 2019-2023 Mac Pro. So that’s almost a decade ago, and sold poorly. It never got a real refresh.
Before that was the pre-trash can Mac Pro in 2006-2012. So that was canceled most of a decade before the 2019 model.
High bandwidth PCIe hasn’t been a thing in Apple world for most of 15 years.
What exactly is the difference between an internal PCIe slot and Oculink or Thunderbolt from an electrical and functional perspective?
