Unless that better performance was at the cost of overclocking older designs, making it run hotter and less efficient. I think Intel got into this groove with a lot of their models for a few years doing this. I get what you're saying, and if its clocked lower than its designed for, power savings are incredible (I've gotten 10 hours on an older laptop that did this from the factory)
