Actually... it depends! Depends of the application and how it handles the workload.
If the app does multi-thread in a right way, the workload certainly will be divided among CPUs, hence, the CPU frequency will be lower on each one ... so the Voltage will be lower too.
However, if the app. maxes out all four cores on a quad core, it will drain battery faster than a tablet with less cores.
Try to see it like this ... you can go from A to B on a sport car at 100mph or 10mph. You will reach B sooner, at faster speed, but you will consume much more gas as well, so your tank will be empty faster as well.
To be fair, more regular iPad activities won't consume lot of CPU cycles (like browsing), so more cores won't necessary mean less battery.
