AMD Faces Lawsuit For Allegedly Lying About The Number Of Cores In Bulldozer Chip

9 Nov 2015 | Author: | No comments yet »

AMD sued over Bulldozer core shortage.

Processor developers commonly overstate the functionalities of their integrated chips–(for instance, Intel’s fixation with clock speed). A class action lawsuit, led by a bloke called Tony Dickey, claims AMD tricked punters into buying its Bulldozer processors by overstating the number of cores contained.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. Part of the problem is that AMD’s multi-core Bulldozer chips combine the functions of what would normally be two discrete cores into a single package, which the company calls a module. The lawsuit was filed with the U.S District Court for the Northern District of California’s San Jose division, alleging that AMD intentionally falsely advertised those CPUs as having more cores than they actually do.

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. But the suit said that Bulldozer cores cannot work independently, and as a result, cannot perform eight instructions simultaneously and independently. 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.

The plaintiffs claim that this results in performance degradation, and average consumers in the market for a CPU lack the technical expertise to understand the design of AMD’s processors and trust the company to give accurate specifications regarding 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.

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.
