Does anyone know how much of a modern cpu the integer multiply unit takes?

I am working on an argument that uses normal computer
integer unit type primitives to calculate algorithm complexity
such as unit multiply and the ability to index arrays and bit strings.
It changes complexity results. Wide multiply by table
look up can't be a primitive because the table grows as
2**<number of operator bits>. The number I need
is approximate percentage of the silicon (percentage
of transistors or gates) a multiply unit normally occupies
on a modern CPU (X86_64 or Arm).
