Lawsuit claims AMD lied concerning the variety of cores in its chips
Processor makers often exaggerate the efficiency of their chips (keep in mind Intel’s obsession with clock velocity?), however AMD is studying that there are limits round what you’ll be able to declare. It is dealing with a class motion lawsuit accusing the corporate of deceptive consumers concerning the variety of cores in its Bulldozer-based mostly CPUs. It might promote that a given processor had eight cores, for instance, when it successfully had 4 — every core in AMD-converse was actually half of a module, and could not function independently. As such, that Bulldozer half could not deal with as many simultaneous directions as you’d anticipate in a real eight-core design. That was sure to be a disappointment when you have been a efficiency junkie anticipating eight-means computing in your gaming PC or server.
AMD hasn’t commented on the lawsuit, though it is notable that the corporate is backing away from the modular chip designs on the coronary heart of this authorized battle. Its subsequent structure, Zen, represents a extra typical strategy that focuses on simultaneous code threads inside every core, like Intel’s Hyperthreading. It might result in bigger processors, nevertheless it ought to be quicker and (extra importantly) get rid of any debate about what a core represents. The large concern is that AMD might pay a heavy worth for its advertising mistake. Even within the lawsuit’s house state of California, hordes of individuals purchased Bulldozer-based mostly computer systems — if the plaintiffs win the day, that would result in a hefty settlement payout.
