The lawsuit against AMD for the 'lie' of the FX processors, continues

The class action lawsuit against AMD over the Bulldozer and Piledrive architectures that brought the FX processors to life continues.

We have to go to 2015 when a class action lawsuit was filed against AMD. That lawsuit was based on advertising for the Bulldozer and Piledrive architecture processors. These processors gave life to the FX series that in theory had up to 'eight cores'. The plaintiffs claim that this claim was completely false.

Lawsuit against AMD over FX processors

The Bulldozer architecture is based on central modules, each offering two cores within a singular module, sharing the resources between each of the cores. That lawsuit alleges that the Bulldozers did not actually have eight cores. This lawsuit alleges that it offers four cores and eight 'sub-processors'. Sharing of resources between Bulldozer cores is alleged to cause performance bottlenecks.

According to the plaintiffs, Bulldozer processors technically have four cores. They have alleged that the acquired processors are "inferior to the products represented by the defendant [AMD]"

AMD has refuted this information noting that "a significant majority" of people use the same "core" definition of AMD. American Judge Haywood Gilliam disagrees and the class action lawsuit goes ahead. This trial will begin at the end of the year. This class action lawsuit will see arguments from both sides, which will meet again on February 5. There the timeline of the case will be decided, where AMD plans to defend itself with everything.

It should be noted that the FX processors have been considered a total failure, since the performance was much lower than that of the Intel Core. The bet for the parallelism in Bulldozer was not fruitful, since the thread of the Intel processors was much better. This disaster forced the company to put aside the processor market to reinvent itself and that has been achieved with the current Ryzen.
