Plus it seems the planet3dnow site has recently discovered the integer DIV unit which is present but disabled for BD is enabled in the PD core. This conclusion was based on a leaked Piledriver/Trinity benchmark and AMD's sw. opt. guides for 15h and 10h/12h families.
The article is written in German so excuse me if I got it all wrong.
