Q: Is this port only for AMD CPUs?
A: No. "AMD64" is the name chosen by AMD for their 64-bit extension to the Intel x86 instruction set. Before release, it was called "x86-64" or "x86_64", and some distributions still use these names. Intel refers to its AMD64 implementation as "?Intel64" previously named "?EM64T". The architecture is AMD64-compatible and Debian AMD64 will run on AMD and Intel processors with 64-bit support. Because of the technology paternity, Debian uses the name "AMD64".
