Memory on executors

Can an executor with fx 64 gb ram with 4 engines (=16 gb each) handle queries with as large datasets as an executor with 64gb ram with only on engine?
Does it differ whether or not the executors and engines are intalled on k8s or vms?

@humanSupafly K8’s to VM’s should not affect query performance

Having 4 executors will give you more cores and hence more parallel threads
