All seems to be true. It really does look like everything in the same architecture is built off the same template, just with cores added in or taken out, with cache added in or taken out, with clock speed added in or taken out.
It does seem that its not "that" simple though. Some things like cache and such seem to be a little three dimensional. A sweet article from ars technica shed some light on this. Definitely a good read. ( http://arstechnica.com/gadgets/2002/07/caching/ )
As far as figuring out pipelining, it seems that pipelining was mainly created to allow for superscalar technology and multiple cores to take advantage of multiple threads. So far, what I've gathered is that each pipeline is either A) A core, or B) A virtual core created by superscalar technology (HyperThreading for example). The first big processor to use pipelining and superscalar technology was the P5 architecture by Intel, which oddly enough, also had a very high clock speed and two pipelines due to a single core with HyperThreading. It also had a stupidly deep pipeline (31-stages?! What is this!? Why?!), and it seems that a deeper pipeline allows for a higher clock rate whilst a shorter pipeline demands a slower clock rate.
Why this is? That, I still havent figured out. Though defintiely have learned a lot so far.
