I'm afraid that chip is too complicated for me. I'm still trying to figure out the 386 :-)

But I did colorize the A19 die photo with Apple's M1 rainbow gradient, just for fun: https://oldbytes.space/@kenshirriff/115256179526128051

If the Apple A19 could be made in the 386's process (1000-1500nm), it would be about 300-500x bigger than its current size in each dimension.

"too complicated", what an understatement! Even the 386 wasn't exactly simple. The complexity of these modern chips is mind-bendingly immense.
