Keep in mind that with Office apps and no or few background processes that most device idle time is simply showing what is on screen and what is stored in memory for active and background applications. I presume if it is half the cores then it would draw less current overall across the CPU silicon area and thus would have an increase of battery life, if processing loads are consistently the same. Would a Core i3 potentially be better for my brother? He said he would rather have battery life than pure power, so if he could squeeze and extra hour out of the Core i3 it would be worth it.ĮDIT - I see that Core i3 is UHD 48EU's while Core i5 is Iris wit 80EU's which might be worth it itself. I assume everyone will advise to just go Core i5, but I've always made due with the lowest CPU spec (Core i3 SP3, Core m3 SP4, Pentium Surface Go) and they handle office apps just fine. Would the i3 be more efficient? Or would it not matter with "race to finish" compute where quad core would get more work done in less time than dual core? The i3 can maintain higher core clocks since it has half the cores and presumable thermals as well. You can already see the extra power allotted to the core i3 because Intel lists the base clock at 3.0GHz while the core i5 base clock is 2.4GHz. Would the Core i3 maintain better thermals than the quad core i5 (1135G7)? Considering I'm always reading about significant throttling on the Core i5 fanless models due to the heat. I'm actually considering the Core i3 (1115G4) because the new 10nm+ Intel 11th gen CPU's are quite powerful, especially in single core and even though it's a dual core, it benchmarks slightly higher than even the quad core 8th gen Skylake Core i7 sometimes! Which I'm still using for my business work laptop and is plenty fast.Īll he will use it for is Office apps. Buying my brother a college Surface Pro 7+
