32-bit

I see talk of CPU's being either 32-bit or 64-bit processors. Information which is often required on download pages

But what is that feature officially called.

i.e What's the inverse of saying "I have a 64-bit processor"?

I want to say: The ??? of my processor is 64 bit

What is the correct term to use for ???

I have looked at a random product on the Intel site and I suspect the correct word for this is "Instruction Set", but I'm not sure.
