Limiting the slots will still allow the OS to use the additional threads. And it's still up to the OS where to put each thread. http://gridengine.org/pipermail/users/2016-March/009028.html Switching it off on a BIOS level will also change the internal operation of the pipeline in the CPU as there are no threads to handle any more.
