AMD faces Lawsuit over Core Count on Bulldozer
AMD faces a lawsuit over the core count on Bulldozer processors, reports legalnewsline.com In claiming that its Bulldozer CPU had “8-cores”. The suit alleges AMD built the Bulldozer processors by stripping away components from two cores and combining what was left to make a single “module.” In doing so, however, the cores no longer work independently.
As legalnewsline.com describes: AMD allegedly tricked consumers into buying its Bulldozer processors by overstating the number of cores contained in these chips.
Tony Dickey, on behalf of himself and others similarly situated, filed a class-action lawsuit on Oct. 26 in the U.S. District Court for the Northern District of California, San Jose Division against Advanced Micro Devices, Inc. (AMD) for alleged violations of the Consumer Legal Remedies Act, California’s Unfair Competition Law, false advertising, fraud, breach of express warrant, negligent misrepresentation and unjust enrichment.
As a result, Dickey argues that AMD’s Bulldozer CPUs suffer from material performance degradation, and cannot perform eight instructions simultaneously and independently as claimed. He alleges that average consumers in the market for computer CPUs lack the requisite technical expertise to understand the design of AMD's processors and trust the company to convey accurate specifications regarding its CPUs. Because AMD did not convey accurate specifications, Dickey argues that tens of thousands of consumers have been misled into buying Bulldozer CPUs that cannot perform the way a true eight-core CPU would.
Dickey is suing for damages, including statutory and punitive damages, litigation expenses, pre- and post-judgment interest, as well as other injunctive and declaratory relief as is deemed reasonable. He is represented by Samuel M. Lasser from Edelson PC in San Francisco, California; and Rafey S. Balabanian, Alexander T.H. Nguyen and Amir C. Missaghi from Edelson PC in Chicago, Illinois.

The main reason people run 64bit Windows is because it comes pre-installed on their Dell, HP, Compaq, Gateway, etc.... The "enthusiast" market has nothing to do with it.
They don't release PAE drivers because it's a waste of resources to do so for such a small user base. It adds unnecessary complexity to drivers and increases the risk of instability.When I said "people" I was including the PC makers.

Hyper-threading is exactly as Intel describes it is, just 2 threads on one physical core. 2 threads on one core scale the same, if one goes to say 1ghz powerstate then the second thread on the same core will.
Whereas with Bulldozer modules, the two units scale independently. "Core 0" in module 0 can scale down to 1 ghz, while "core 1" can scale down to 600mhz in module 0 at the same time and can act on their own.
Funny thing is about the whole lawsuit is it is only the FX 8 series that is mentioned and being targeted. AMD's module design is used on all of their APU's and cpus now, but there is no mention of the FX 6, 4, A10, A8, or A6 series at all.
Sorry to nit pick but the cores low power mode is 1200MHz next downstep from there is off/parked
