If you want to compare old with new you have to do it with comparable settings otherwise we're into the territory of feeling. As a software developer I have the T-shirt for that one after someone said something took 3 hours that normally took a couple of minutes in an earlier version later admit he'd had a bottle of wine to drink and fallen asleep at the computer! Turned out it was now about 10s faster after log analysis.
Judging from your renders I'm guessing the two are using different atmosphere models? That can be a major player in rendering speed and that tends to balance out speed improvements from one version to the next.
