Simple, the module is really the core itself (in other words, a module should be called a core). And inside the core, there's two clusters (AMD's marketing calls them cores, which can be misleading). One cluster is one hardware thread.

On a side note: CPU World: AMD Opteron 6200 alleged benchmarks 

i'd say marketing department need to bear some responsibilities on this "huge" disappointment. they created d hype which made some ppl thought that BD would be Intel slayer. for those who closely follow AMD in recent years, they should know there's no way AMD can close the performance gap (let alone slayin Intel) with Bulldozer, which is something totally new if compared to previous gen. The marketing guys shouldn't labelled BD as FX series thou, coz FX still hold a special status in some AMD fans (or most), & when reality hits, it sure pains more.

undeniably BD is a let down, personally d power consumption (when overclocked) surprised me d most. but d things are here, so either i go blue camp or i just bare with it. no one is committed to use one brand of chip only, so it's always up to d users to choose what suit themselves d most. it amuses me to see some even go to d extent like having breakup with gf (those swearing they'll never buy AMD again) because they feel cheated. for me, i'll just stick around for a 'lil longer (since I've ledi got an 990FX board & doesn't want to go thru d hassle of changin board & chip). whether BD architecture could be foundation for better product lines in future is remain to be seen. fingers crossed & i'll keep reminding myself to stick my feet on d ground regardless what being "advertised" next time. 

With all those bad reviews, it seems on oct 12, AMD stocks still open up higher than previous day lol.

I just realise Intel is practically 4.5x bigger than AMD lol...

The unboxing of the FX-8150 if anyone is still interested in knowing what is inside the box. Looks like it is a special edition with a lot junk freebies that you pay.
