What's the correct Processor Architecture type to pick during Debian Installation?

I am trying to install debian on local computer with Windows 7 OS and intel core i5 processor.

On the download page. I was asked to select my processor architecture with the following options listed

amd64
armel
kfreebsd-i386
kfreebsd-amd64
i386
ia64
mips
mipsel
powerpc
sparc

From my little research, i would say my processor architecture is not listed above as intel core i5 is a processor architecture in itself. am i right?

If so, which do I select for my debian installation?

No, i5 is market name. Architecture is AMD64, with various microarchitectures being sold under i5 brand.

AMD64 is original name for AMD's x86 extension, providing long mode (64bit operating mode), while models of various microarchitectures that Intel sells under i5 brand are implementations of it.

Just select AMD64. See http://en.wikipedia.org/wiki/X86-64 And Intel core i5 is one of its implementations.
