AMD sued: Number of Bulldozer cores in its chips is a lie, allegedly

Re: A bit of a Dickey move

So the boy didn't read the cut sheet from AMD when he bought it. The question of cores is one that will have to address what kind of cores now that heterogeneous chips are increasingly becoming the norm. What does it mean to say something has X cores when the chip can combine CPUs (x86 and/or ARM), FPUs, GPUs, DSPs or even the occasional FPGA? Do FPUs matter if software is optimized for GPUs?

Of course, such a ruling will be avoided if AMD proves its eight-core Bulldozer processors do not drop to four-core performance in multithreaded FPU benchmark tests.

Another problem entirely as it may well depend on the bit width employed by the benchmark. What happens if it doubles the performance of a four core at 128 bits but not at 256 bits?

Regardless, this kind of "I didn't understand what I was buying" crap needs to be bounced out. Would he sue because he bought a Tegra 4 because the five cores didn't work like they thought?
