1. AMD64 is a lot easier to decode than the legacy i86 8/16/32 bit instruction set.

2. Decoding took a significant portion of the chip when they were a million transistors. The m1 has 16 billion resistors, decoding is a much less significant fraction of the chip.

Complexity isn't only about transistors, but also about delay.

And sure, there's pipelining but than your limited by latency.
