No success with searching 1st for "sandybridge" (one word) :-(, so
official docs have a "space" ("Sandy Bridge")
[1] says:
"Sandy Bridge is the codename for both the Intel microarchitecture
innovation following Nehalem and generally for the associated family
of 32nm processors based upon that microarchitecture."
For the GPU there is "Processor Graphics".
So mine seems to be called "Intel® HD Graphics 3000".
Hmm, I remember darkly intel-ddx uses the latter.
Anyway, somehow all that stuff is still confusing me.
