I still think it's funny that we're benchmarking phones of all things.
why? the note3 is more powerful than some user's desktops/laptops.
Good luck using all that power. Not only do most app developers design their programs and games for the midrange devices most of the time (unlike the PC world, last I checked there is no Crysis-level game bringing phones to their knees), but right now trying to run your phone at the max will rapidly drain your battery and/or overheat your phone.
The reason why these companies "cheat" - not that I'm justifying it, just explaining - is because their CPU cores run at lower clock speeds most of the time (which is how mobile CPUs are designed to operate) to save battery and minimize heat. So they effectively throttle for most tasks but run at max for benchmarks. Somewhere along the way one of these companies decided to do it, so now a number of them do it. It's a bit misleading and unfortunate, but it is understandable why.
In the desktop space you very well could run your CPU or GPU at max frequencies very happily for video encoding, gaming, or mining, but it's less likely to occur on the mobile side, except in bursts ("race to idle"). I'm not saying there aren't any CPU or GPU intensive apps out there, and more and more phones will in the future be capable of the same types of tasks as desktops, but right now what
most users want is a fluid, smooth experience on smartphones, and software/GUI matters a whole lot more in that area when you are comparing current generation phones. There is a little benefit talking about 2.2 GHz versus 1.5 GHz or whatever comparison you can make, but it is only a little benefit even when all other things are equal. It's not as dramatic as on the desktop side when you can run at full tilt all the time if you really want to.
Benchmarks are useful for comparison to a small degree, and maybe are beneficial for shopping for a device for the sake of longevity (i.e. you want your phone to be good for 3 years or more), but we tend to give them a little too much weight as mobile enthusiasts on the whole.
