Yes, it's different. 32-bit x86 support is for compatibility with older software. x32 is a completely new thing that has nothing to do with compatibility. Basically, it's everything that AMD added to the 64-bit variant of x86, except the actual 64bit pointers. So you get more registers, access to additional instructions, and so on.
