how did you come up with that conclusion?
It means that two Bulldozer cores will only be 80% faster than a single K10.5 core, not 100% (like a dual core K10.5), or more preferably, over 2.0x as it should be with a new microarchitecture. They are trading off performance in order to add more cores.
It means that Bulldozer core design is tailored in such fashion that achieves 80% of it's full potential 'cos of the shared design. If it didn't used modular/shared approach it would run 100% of it's theoretical performance!

On a side note point me out to the new CPU architecture that was 2x faster than it's predecessor at the launch?

003 here's word of advice: don't be so determined about the stuff that you don't have clue
