The only real difference here is the size. All of the int types here are signed integer values which have varying sizes

  • Int16: 2 bytes
  • Int32 and int: 4 bytes
  • Int64 : 8 bytes

There is one small difference between Int64 and the rest. On a 32 bit platform assignments to an Int64 storage location are not guaranteed to be atomic. It is guaranteed for all of the other types.
