Look that this is not true. If one core is not running any task, the idle task (if not polling) does "hlt" and the "what they call Fetch And Deliver" engine will be dedicated to the other core. Also, because the halted core not not issue any op to the execution engine, full resources will be available for the running task. There are many docs available inside the Intel developer web site that explain this.
