Good post. One thing to note is that the 3090 being 8 times faster is not very correct statement. The author is comparing FP16 3090 with FP32 M1. The difference between them is more like 3-4 times for FP32. Even that is not true FP32 for 3090 as tensorflow uses Nvidia's AI32 by default for convolution.
