I believe that Apple is effectively doing some binning with the M1: The intro MacBook Air has one less GPU core than the higher-config version or the MacBook Pro.
It would make sense if those were identically-made M1s where one GPU core didn't test well and thus had its fuses blown. Between the CPU and GPU, the GPU cores are almost certainly larger anyway; the GPU cores would therefore have higher probability of defects.
