I'm considering the following two cpu models for my next laptop: Intel® Core™ i7-4700mq, i7-4500U processors
I understand that the 4700 mq will give me much more computing power, and that the 4500u should generally give me more battery life
My questions are: is it at all true that the 4500u will give more battery life (in a web surfing scenario let's say)? If yes, roughly how much more? Given all other factors equal.
(I'm reading in several places that having more cores does not create a battery consumption penalty if the additional cores are not actually active. I also understand that the hasswell serries are by themselves very good in power comsumption, even before getting to the U sub-series)
p.s. (The laptop is intended to serve me in various scenarios, the important of which are: 1. Programming. In this scenarion I will be plugged to a power cord, and willing to have maximal computation power. 2. Surfing the web, using office and the like, while being outside and wanting lot's of batterly life)
