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.

pfff...
AMD can easily win this. Some losers just trying to make money.

Another frivolous lawsuit that should be summarily dismissed. The cores of a bulldozer CPU do work independently as can easily be seen by running a utility like HWinfo. This shows the speeds of each core changing independently of each other which proves that they do function as separate units.

I would really be shocked if this so called (Dickey) guy actually wins this law-suit,In my opinion just another loser that is looking for a free-ride on someone else back!
I am curious tough as some have Stated Amd already being in trouble,this could be the Final nail in there coffin,Zen cannot come soon enough I tell you.

well i remember pretty clear that at the launch of this cpu's, you, Hilbert, presented some info on this and said something about 7,5 CPU or something like that.
Also how can this lawsuit stand when the performance of the CPU's drastically depends on how a application uses them, and as far as i know amd's 8 core cpu's work as they should in multi threaded apps and use the cores properly.
or maybe i'm missing something, anyway the suit it's pretty shady.
Yes, but AMD themselves market the processors as 8-core processors which is clearly not true. It's not as bad as if Intel would say that the 6700k is an 8-core, but it's still not very accurate.
To expand CPC_RedDawn's answer, AMD's FX-8350 (we'll take this as an example) is not a true 8-core processor. A core needs (among other things) one ALU and one FPU (else it cannot be classified as a full core by today's standards). AMD's cores in the FX-8350 do not have one FPU per core, but one FPU per 2 cores.
If we put this in perspective, the FX-8350 has 8 ALUs and 4 FPUs. You can see how this is misleading. They are not 8 full cores. They are going to have the arithmetic performance of 8 cores, but the floating-point performance of 4 cores.
I believe this is what the lawsuit is referring to but it's quite vaguely explained.
Not good, not good at all..
This is way worse than the 3.5 mem issue vn went through. It's out and out *****ulent and they will certainly take a big hit on this one as that is a lot of cpu's to replace. What is interesting is that the company just shed it's graphics division and now news of this.
Things don't bode well for them and this is the sort of things that ends companies.. I don't think it will be the case with them but it is really going to hurt them.
I can't recall the specs on the PS and X1 but don't both of them use bulldozer cpu?
I don't think it's as big as Nvidia's 3.5Gb issue. At least not in my perspective.
I believe it was common knowledge for the tech enthusiasts, but the average consumer would surely be mislead. Many of us here have known since the beginning that the FX-8350 cannot exactly be called '8-core' due to it's ALU/FPU configuration (see my quote reply above).
Ps:
You might say that the FX-8350 actually has 8 FPUs. That is correct, but it's not how they work. They are 128-bit FPUs, which couple up to perform 256-bit AVX instructions. Making them 4 effective FPUs.
