Im really wondering how powerful the GPU of a new big iMac is going to be.
The M1X is rumored to have 16 or 32 GPU cores
The Mac Pro is rumored to have 64 or 128 GPU cores.
If we extrapolate the performance by simply multiplying the current M1 8 core GPU , we would get the following Metal scores:
M1 8c - 21.168
M1X 16c - 42.336
M1X 32c - 84.672
M1X 64c - 169.344
M1X 128c - 338.688
The current iMac with 5700XT has a score of 60.000.
So if the new MacBook Pro get a 32core option, it would be more powerful than the best iMac.
So Apple could just put that same M1X in the new iMac, and have better performance than the last, but would it also be possible they put a 64core in it?
Based on your post, I could see the larger iMac having a standard 16 GPU core.
Maybe, the 32 GPU core would be available as a built to order option.
