Assuming GB makes no system calls, that still leaves any OS background tasks and the way the scheduler handles them. Granted, those may not be significant in any particular benchmark run.You have to understand that the OS is irrelevant for Geekbench. Only the compiler has impact. Of course compiler choice correlates with the OS but the fallacy is to equate performance differences to the OS.
What we do know is, that gcc produces faster code than msvc, therefore we are seeing higher scores under Linux than under Windows.
