It will be more meaningful to test it with the Galaxy Book running the Qualcomm SOC to understand the difference in performance, thermals and battery life. As expected, despite the low power processor, Intel is not quite there yet when competing with the likes of ARM SOC over battery endurance. Even if Lakefield is faster, I don't expect it to be meaningfully faster to the point that the target users will feel a significant difference. The target audience for this sort of laptops are more for people on the go, and needs a laptop for light work, i.e. surfing net, word processing, etc. Running an intensive work is unlikely the use case.
