We have to be careful as Sandybridge isn't a brand or product name but a
code name, and Intel marketing gets upset if we put the codenames into
user visible strings. (I can understand their need for control over
product image and branding, but the codenames are much easier to
understand!) The popular form for the *bridge, *well, *trail, *view is
as one word with a single leading capital letter. The codenames are,
I believe, or at least once were, the names of geographic features
around the Intel campuses. And different types of features (rivers,
hills, etc) were used to denote different types/combinations of chips.

Wikipedia is the best source for such information as product to code
name to features. Though ark.intel.com has all the information if you
have a glossary (wikipedia) to hand, and have product names to search.
