Super common though. Everyone from Hetzner to AWS does this, unless you specifically pay for full allocation, which is typically ~2x the price.
Chances are you are using systems that do this and you haven't even noticed.

There's the 't' series of instances that offer burstable CPU. AFAIK still 1:1 on memory though, and there's models that allow you to pay to stay un-throttled when using t family instances vs. getting throttled when out of burst credits.
