These are just ES scores,not final.So until you see retail score so bad in memory benchmarks(as in AIDA),don't put so much faith in these results.
As for BD ver2 it's actually Komodo,not ES version 2. Komodo is known as BDver2 in some compiler suit updates as Dresdenboy showed us many months ago. It is a souped up BD(Orochi) with new ISA support and some tweaks(probably similar to Deneb=>Llano ).
