Detect Apple silicon GPU core count

Question

Similar to this question, I am interested in detecting the exact GPU inside a Mac equipped with Apple silicon.

I am interested in knowing the exact GPU core count.

sysctl -a | grep gpu

or

sysctl -a | grep core

does not seem to provide anything useful.

Answer 1

You can use ioreg like this:

 ioreg -l | grep gpu-core-count

You can also look up an object with class that's named something like AGXAcceleratorG13X and see all of its properties, gpu-core-count will also be there.

Answer 2

To detect GPU core count on Apple Silicon architecture you can use this command:

system_profiler SPDisplaysDataType
