AMD sued for misleading with number of cores in Bulldozer series




AMD has sued the manufacturer claimed that the Bulldozer architecture would have eight cores, while there are actually four. The plaintiffs propose include that AMD thereby committed fraud and misled customers.

Bulldozer It writes Legal Newsline on his site. The plaintiffs, led by Tony Dickey, find that AMD customers have been misled by the chip sealing to eight cores, while there are actually four. The cores Bulldozer processors do not use all of its own L2 cache and own execution paths. That is, two cores share L2 cache and floating point unit. By sharing various parts of the modules, which the size remains smaller. How this works exactly, depth Tweakers in 2011 in a background article on the release of the Bulldozer architecture.

Prosecutors believe that by combining different components, there is no question of eight separate cores which individually do their work. The result is that Bulldozer processors would perform less compared to processors with eight “real” cores. Still, AMD claimed according to prosecutors in various manifestations that the processors have eight cores and that consumers could not have the technical knowledge to understand how it really was with the chips. These consumers bought according to Dickey chips that could not perform at the expected level.

Dickey AMD complained to the district court in the Northern District of California for damages after AMD may have to pay a fine. Furthermore, AMD should also pay all legal fees.
