I'm surprised how fast the iPhone CPU is compared to the Xbox One CPU (for this application).

PX4/XB1 use a fairly low-end AMD CPU (Jaguar core, ~1.6GHz). Apparently it also does not quite appreciate heavy use of 64 bit multiplies (as used in xxHash64 for example).

Modern phones (e.g. iPhone 6) in terms of CPU are actually very impressive indeed!
