uarch names used to be different from that. But looking at wikipedia,
things have gone completely apeshit after skylake :-/

We used to have one microarch and then a laptop,desktop and server sku,
but now each of those has a separately named microarch, so where we had
one new name each year, we now have at least 3. No wonder I've no
sodding clue anymore.

/me stmps off to get a beer to forget all I've seen ...
