Re: Which processor exactly has a 9401-150?

It is still the same. You can bet there are only a couple of masks for the
POWER CPUs and that depending on tests and yield you get the 4-6-8-10-12
cores. Even in the announced POWER10 they actually came out and said "The
chip actually has 16-cores but due to yield issues we are certain that at
least 1 core will have something wrong, so we only market it as a 15-core
max CPU".
You can also see that in the list prices. As core per socket count goes up,
so does the price.

Interestingly, the board also hosts a PowerPC 603e (EMPPC603eFE-83) from

Back in the day, IBM would offer systems with CPW ratings that spanned up
to a factor of 10 for the exact same CPU, which was just clocked up or down
in order to meet CPW targets. It kind of rubbed some of us wrong to know
that the CPU was clocked down for "marketing" purposes.
