As majority of current hardware use some form of dynamic CPU frequency

have the current hw.cpuspeed displayed somewhere in the header lines of

on the display.
Is it safe to plan for 9.999 GHz maximum CPU frequency?
For each core?
Yes. Just the value that hw.cpuspeed reports.
They say that without supraconductivity it hardly can be exceeded, but I
am not an expert. ;-)
My question was if four digits in top(1) for CPU clock frequency in MHz is
enough, or if five digits are needed to be reserved for a foreseeable
future.
