Assume that 64 bit CPU performs only 64 bit requiring tasks , and assume
that 32 bit CPU performs only 32 bit requiring tasks . My comparison is
based on this assumption . There are a huge number of jobs that they only
require 32 bit operations . For such jobs , it is not necessary to use 64
bit processors when  there is a need to a large number of processors for
such tasks collection .


For a few jobs , these may not be important , but in a factory using
processors in large numbers , total of such small number of watts may
escalate to a large amount . This means unnecessary cost when a year of
operation is considered .


Thank you very much .
