Bulldozer CPUs
October 2015: A class-action lawsuit was filed against Advanced Micro Devices, Inc. for allegedly misrepresenting the specifications of its Bulldozer line of CPUs. Specifically, plaintiffs claim that the company misleadingly represents that the Bulldozer CPU has eight cores when, according to plaintiffs, it functions as a four core CPU. (A core is an independent processing unit that performs one calculation at a time. Because each core is able to operate independently from the others, a CPU containing multiple cores can perform multiple tasks at the same time. Thus, an eight-core CPU can perform eight tasks at once.) (Plaintiffs filed an amended complaint in 2017.) (Dickey et al v. Advanced Micro Devices, Inc., Case No. 15-cv-4922, N. D. CA.)
