Earlier quoted context omitted.
So Apple would need 16x its GPU Core, or 128 GPU Core to reach Nvidia 3090 Desktop Performance. Or roughly 480mm2 Die Size, 192W TDP excluding memory controller and interconnect. Doesn't look too bad for Nvidia, especially when you consider 3090 is still on Samsung 8nm, which is equivalent to TSMC 10nm, compared to 5nm on Apple M1.
The rumors say they’re going to have a high end of 128 gpu cores by using 4 32 gpu core chiplets.
It would be great if they did it the eGPU route with TB4, in a slick package
