M1 from November 2020 has 16 billion on a 5mn process node at 39W TDP.
M4 from November 2024 has 28 billion on a 3mn process node at 22W TDP.
And remember that 5mn process node is just the length in one direction (although it isn't 5mn), so density technically increased by (5^2 / 3^2 = ) 2.7x during that 4 year period.
That is less than the 4x one would expect, but it is far from Moore's law being dead.
For the same cost* was left out of my post, but it is extremely important to Moore's law not being dead.

Mac Mini M4 is cheaper than the Mac Mini m1 and has better base specs. And the MacBook Air M4 is cheaper than the MacBook Air M1 and also has better base specs.
