Will depend on the quality
On the best bike I'm currently still using a Campag Super Record Cassette which has @ 8000km on it - through I think 3 KMC XL chains. Cost - exorbitant, prob over £600!
OTOH I get through a fair number of chains and mid priced cassettes on my other bikes, usually in about a 3:1 ratio. My daily commute bike used to get through about a set each year with the abuse that a commuter gets - I expect but don't always get more on my better maintained machines.
