WebJun 6, 2024 · C and C++ use 32 bit int because otherwise there is no 32 bit type available (char = 8 bit, short = 16 bit or you have no 16 bit type, int must be 32 bit or you have no 32 bit type). Swift on 64 bit devices has Int = 64 bit, but also has Int8, Int16, Int32 and Int64 so the problem that C has is avoided. – WebFeb 11, 2024 · 1. The compiler could generate the necessary 32 bit instructions to do 128 bit math on a 32 bit H/W architecture. But, they chose not to. To use 32 bit instructions -> 64 bit math or 64 bit insts -> 128 bit math, consider a multiply: For 32 -> 64, it takes 3 multiplies and two adds. About the same for 64 -> 128.

Generally, even code written for a 64-bit platform uses 32-bit variables where values will fit in them. This isn't primarily because arithmetic is faster (on modern CPUs, it generally isn't) but because it uses less memory and memory bandwidth.
