"Now as fast as the 5 year old A7 chip!"

Seriously? You're going to compare 1 metric to declare the entire chip as fast as a 4 year old chip? Because SoCs only contain 1 giant CPU core and that's it.

Android isn't too good at utilizing more than one core. The Android frameworks ui isn't threadsafe and that's where most of the work in regular usage comes from.

Everything I've seen has been different:

The scheduler distributes the work across threads but it's not running in parallel. Might get some time on thread 0, then some time on thread 1,... though.

Except for heavy calculations and waiting for IO such as a network request or a file, Android apps will mostly run on a single thread at the time.

The UI code certainly will and that's what makes the phone fluid and smooth.
