Suspend vs lowest freq power usage difference can be significantly larger than between lowest & highest freq. But Suspend transition times are longer, especially with old (x86) processors and they didn’t have as many suspend states.

There are a few old x86 chips where the lower C-states exist but have to be avoided entirely to avoid nasty bugs, which doesn't help matters.
