This would correspond to a clock speed of 4GHz (billion cycles per second),
since all PICs require 4 clock cycles for each instruction cycle.  To the
best of my knowledge, there is no microprocessor on earth that would clock
that fast.

The fastest PICs are rated at a maximum external clock frequency of 33MHz,
or 121ns instruction cycle time.

All PICs can operate on an internal RC oscillator which has a fixed nominal
value of 4MHz, or 1 usec instruction cycle time.

Hope this helps
