Optimal pipelength

Is there anything like an optimal pipelength?
Looking at Pentium it was using 4 steps and 5 on Pentium MMX.
It was not longer on Pentium Pro or AMD K5 and K6.

Now Intel and AMD are on 18-19 but ARM64 only on 11-12.
Converting x86_64 to something better should take some steps- but how many?
