You weren't talking about the amount of cores. You were just wondering why somebody would need so much power.
Faster phone = tasks that you listed can startup / be accomplished better. If you want to bring up your camera quick to take a picture of something that's happening right in front of you, you'd want it to come up as quick as possible. A more powerful phone can do that.
Amount of cores.. power.. whatever, i'm not trying to be technically correct in what i'm saying. I just mean what is the obsession with so much speed on a phone.
I understand that. But apps start up very very quickly anyway, Safari opens up and loads google in under a second, email is loaded up in half a second, mynetdiary diet app is loaded in half a second, the camera app loads ready to take a picture in a second, Dominos pizza app starts up, finds my location, and loads my local restaurant menu in under 3 seconds. And those are from cold launches with the app fully closed. If I leave all the apps in a paused state like I do 99.9% of the time every app bar big games and stuff are up and ready practically instantaneously.
I'm not sure I need it any quicker really. For small <20mb apps which is most, it could physically not be much quicker. It is as quick as leaving a window open on a proper PC and then selecting it.
It's like the old days, I would buy a new processor to make the desktop more responsive. Well now we have reached the point where all top end CPU's matched with SSD's within the last 2 years are basically just as fast as each other on desktop use such as browsing your documents, opening control panel or chrome etc. Upgrading your rig for a more responsive desktop is now essentially impossible, unless you do an insane amount of multitasking their is very little difference between last years top cpu and this years top cpu. This is where smartphones are at now in my opinion. But the difference is desktop PC's are always going to have games and professional level applications that benefit from as much power as you give it, and this is the reason to upgrade. But I don't think this exists on smartphones, people are happy playing Angry Birds and Temple Run. No one wants Crysis 3 on phones. Even if Crysis 3 was on phones people would play it for 5 minutes realise it's awkward as **** and never play it again, and yet again launch temple run which would of worked on any decent smartphone in the past 3 years.
So we have established apps on iOS atleast launch very fast (I don't know about android, i'm sure they launch quick though). It's pretty clear by looking at top games in the app store that every single one of them is not graphically intensive or very cpu intensive, so more power isn't really needed there either. The newest smartphones play 1080P great now as well. What else is left ? barely anything. Higher quality cameras that capture at higher resolutions with less compression (Especially true of video) is actually the only decent thing I can think of where a faster CPU would come in handy.
I think phone manufacturers should focus their efforts now on properly new features, both hardware and software. The speed race was good and definitely necessary for a few years but now we've got very fast phones that do what 99.99% of the population need their phone to do, so it's time to invest and research elsewhere.
