Im a little confused, apparently the mac pros were updated with penryn processors but apple's webpage still says they have harpertown processors? What am i missing ?
Penryn is the code name, Core is the name of the microarchitecture, Xeon is the brand name, Harpertown is the series name. Confused yet?
You're missing that they aren't "still" Harpertown, they were Woodcrest (4 core) and Clovertown (8 core) before January.
