Generally, a higher compression ratio equals more power. As does an increase in boost. An engine running a higher compression ratio generally must run a lower level of boost (unless it runs on avgas and has water injection!).
I know with the low boost VA setups, they run slightly less boost and power on the standard CR.
Looking at it from a basic level, both a low boost and high boost engine should be able to give the same amount of power; ultimately the power is just pressure in the cylinders isn't it. So say 100bhp equals pressure X inside the cylinders, in the high boost engine it runs say 1bar of boost to generate that pressure, and in the low boost it generates 0.5bar and still generates pressure X because of the higher CR.
Does my waffling make sense, can you see what im getting at?
