It's nothing to do with silicon. iOS is a ancient platform that under the covers has very basic capabilities, no background services, very limited multitasking essentially a toy OS. Android has all the needs of a full grown up OS.
If you want performance, write C and compile to NDK, if you want quick development, use SDK and Java syntax which compiles to device targeted, near native execute speed davlik.
This comparison is mostly clickbait nonsense.
