The OP was asking if the a 100 CPW machine was running at 50%
CPU utilization, does that mean he's only using 50 CPW?


The CPW workload does not consume 100% CPU, so no a direct
comparison of 50% CPU equating to 50% of the CPW cannot be made.
The targets for CPU utilization vary based on the number of
processors and queuing theory.

Or for example, if I've got a 1000 CPW machine I run at 80%
usage, so I'm using 800CPW and I upgrade to a 8000 CPW
machine, can I expect to see CPU usage at 10%?

I really wish it were that simple! Things like quantity of
processors, L2 and L3 caches, memory card speeds, partitioning,
etc. can have a huge impact to the relationship between CPW
rating and measured CPU utilization.
