To which family does intel core i5 processors belong to? x86_64 or i686.

I was installing MinGW. I know it auto selects i686. But i686's are all 32 bit right? and intel i5 is actually a 64bit processor. This sprung up the doubt as to which family does it belong to?

THanks

Both. When running in 64-bit mode, it is x86_64. In 32-bit mode, it is i686.
