Workstations with dedicated GPUs & vram still have the edge. To their credit, this chip is at the top end for an integrated iGPU, but integrated GPU perform worse in general and don’t think the M1 has really changed this outlook. Unlike a system with a dedicated GPU, the higher resolution and FPS fundamentally competes with bandwidth needed for CPU tasks. It’ll be difficult to get better GPU performance due to the M1’s shared memory architecture. “iMac offers two Thunderbolt ports” – somehow I can already guess that these don’t support egpus. Last I heard Arm doesn’t scale up well, while x86 doesn’t scale down well so we’ll see if M1 chips are all typical Apple marketing hype once reviewers get their hands on these. I think it still remains to be seen whether it’s a good processor in the desktop space where power limits aren’t nearly as much as a concern.
