Are all cores unlocked?

Unfortunately, Bulldozer doesn’t do conventional SMT (which is what
Intel usually¹ means by hyperthreading). It has two integer cores
sharing a wide floating point engine and level 2 cache. This combination
is what AMD call a “module”, but they will be selling it as two cores.

So a 16 core Bulldozer will have 16 hardware threads.

A module takes more power and area than a traditional core with
hyperthreading, but you should get more performance out of it, too.

Sorry,

James.

¹ Hyperthreading is an Intel trademark, and, as such, means precisely
what Intel wants it to mean at the moment. This can change (it means
something different for the Itanium).
