Intel multi core architecture


So this tells me you really don't even know what you are looking for.

"multi-core" is not an architecture. It is something that can be incorporated into the design of a processor. It basically means there are multiple processors on a chip that share some resources that are also on the same chip (not entirely accurate but true enough for a simple explanation)

An architecture is the underlying design. For example, the intel "core" architecture:
