It looks like AMD is being taken to court over misrepresentation of the CPU core count on its “Bulldozer” architecture. Tony Dickey, who is representing himself in the U.S. District Court for the Northern District of California has accused AMD of falsely advertising the core count on its latest CPUs. He claims that because of the way they are physically structured, AMD’s 8-core “Bulldozer” chips really only have 4 cores.
The lawsuit says that Bulldozer processors were designed by stripping away components from two cores and combining what was left into a single “module.” In doing this the core no longer work independently. Because of this Bulldozer cannot perform eight instructions simultaneously and independently as claimed. That is how a true 8-core CPU would work. 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.
