This had to happen eventually. AMD has been dragged to court for misrepresentation of the number of Cores that make up its line of FX processors under Bulldozer architecture. Tony Dickey, who is representing himself in the Federal District Court for the Northern District of California, accused of AMD misleading advertising exercise in the number of cores in its latest CPUs, and said that the way in which it is structured such architecture, the AMD Bulldozer CPUs 8 cores have actually only 4 cores.

The lawsuit alleges that Bulldozer processors were designed by stripping away components from two cores and combining what was left to make a single “module.” In doing so, since the cores do not work independently. AMD’s workaround tricked software (particularly OS schedulers) into thinking that a “module” was a “core” which had two “threads” so we can say that an eight-core FX-8350 would be seen by software as a 4-core processor with 8 threads.

Because of this, the AMD Bulldozer CPUs can not perform eight instructions simultaneously and independently as claimed, or the way a true 8-core CPU would. Dickey is suing for damages, including punitive damages and legal damages, litigation expenses, pre- and post-judgment interest, as well as other injunctive and declaratory relief as is deemed reasonable. Apparently very offended the guy or just want an extra advantage to pull out ahead of the Christmas play.
