Lawsuit claims AMD lied about the number of cores in its chips
Processor makers regularly exaggerate the performance of their chips (remember Intel's obsession with clock speed?), but AMD is learning that there are limits around what you can claim. It's facing a class action lawsuit accusing the company of misleading buyers about the number of cores in its Bulldozer-based CPUs. It would advertise that a given processor had eight cores, for example, when it effectively had four -- each core in AMD-speak was really half of a module, and couldn't operate independently. As such, that Bulldozer part couldn't handle as many simultaneous instructions as you'd expect in a true eight-core design. That was bound to be a disappointment if you were a performance junkie expecting eight-way computing in your gaming PC or server.
