Who knows?

100 mostly idle users doing small optimized selects is a far cry from 80
users with rapid response requirements doing a constant heavy stream of
inserts and updates to tables with multiple indexes and foreign-key
constraints while the other 20 are doing large reporting and analytics
queries. Both use-cases match the above description.

To get a useful answer you will need to provide lots more detail about
the nature of the workload and expected responsiveness.
