ios - How does iPhone with 1GB RAM have similar performance to Android phones with 2GB RAM -


with release of latest iphone 6/6+, have been wondering how iphones compete against competition lower ram. fundamental difference in os lets ios run on less beefy hardware, ram?

the fundamental difference number of layers between application , hardware.

this pure subtraction, in android application running inside virtual machine , kind of abstraction has lot of downsides, including lower performance, promise art runtime improve lot situation (http://developer.android.com/preview/api-overview.html#art).

in ios, there's no such thing, application running directly in operational system, there's huge difference because apple every year tries improve low level apis, sample can use metal api (https://developer.apple.com/metal/).
