AMD faces lawsuit claiming the company lied about number of cores in Bulldozer …

AMD faces Class Action Lawsuit over Bulldozer Based CPU Core Count Claims.

Processor developers commonly overstate the functionalities of their integrated chips–(for instance, Intel’s fixation with clock speed). Still, this could mean big trouble for AMD, as it could be chased for a large amount of money if the plaintiffs emerge victorious and the company is found guilty of willfully deceiving consumers.When AMD (Advanced Micro Devices) had introduced their bulldozer architecture, they had spoken regarding their design being a 3rd way to approach SMT (symmetric multithreading) just like Hyper Threading at Intel and the true multi core processing in which multiple discrete cores reside on just one die.It is nothing new that processor manufacturers regularly exaggerates the performance of their chips, (recall Intel’s obsession with clock speed?) well AMD is finding out the hard way that there hard and fast upper limits to what you can claim and get away with. The complaint stems from claims that AMD overstated the number of cores contained in the chip, the lawsuit says that while AMD advertised Bulldozer as having eight cores, it only really had four, due to the unique design, which combined functions of what would be two discrete cores in to one module.

AMD is mired with a stinging class action lawsuit indicting the company of misguiding consumers about some cores of its Bulldozer-based Computer Processing Units. This lawsuit has been filed by Tom Dickey at the US District Court, San Jose Division, California which alleges that AMD has deceived their customers by overstating the amount of cores in their bulldozer processors.

The company promote that a certain processor comes with eight cores, but in reality it only had four — each core in AMD-speak was just 50% of a module, and couldn’t function autonomously. 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“.

AMD is currently being sued for damages, including statutory and punitive damages, pre and post judgment interest and litigation expenses along with other injunctive and declaratory relief as is deemed reasonable. AMD hasn’t remarked just as yet regarding the lawsuit, though it’s worth noting that the processor maker is pulling back from the modular chip designs at the center of this legal scuffle.

Dickey points out that the average PC buyer do not have the necessary technical expertise to understand AMD’s design of processors because they trust the tech firm to provide accurate specifications on its CPUs. According to the lawsuit AMD is guilty of violating the Consumer Legal Remedies Act, California’s Unfair Competition Law and of committing false advertisement, fraud and breach of express warrant. Its next architecture, Zen, epitomizes a more usual line of attack that concentrates on concurrent code threads inside each core, such as Intel’s Hyperthreading. Because AMD did not convey accurate specifications, the suit argues that tens of thousands of consumers were misled into buying a Bulldozer CPU that can not perform in the same way as a true 8-core CPU.

The definition the lawsuit is looking at is how the core can perform instructions simultaneously or independently without the other cores which the bulldozer apparently cannot do. Since AMD failed to disclose the accurate specifications for Bulldozer, the lawsuit claimed that thousands of buyers were deceived into procuring a product that was unable to perform the way it was promised. In the lawsuit’s bulwark of California, if throngs of people who purchased the Bulldozer-based computers win in the legal battle, they are cinched to receive a whopping settlement amount. In order to do this, AMD has started with a couple of discrete cores and eliminated some of the duplication logic before fusing the pared down cores into a shared, single design. It also alleges that typical consumers don’t have enough technical knowledge to understand how these computer chips work from inside and that is how AMD has misled them.

Dickey’s lawsuit is seeking unspecified damages as well as litigation expenses, interest and various other declaratory and injunctive relief deemed reasonable.
