Keep in mind that one of the finer points of making money in the semiconductor industry is yield management, especially when you're cutting larger dies.
These days you don't just toss a chip when it fails a test - you design the tests to exercise different physical regions of the chip to identify the location of a defect. You also design the chip in a way that allows you to power down different regions and behave like a lower priced part.
So a defective quad-core CPU might be sold as a dual-core part, or as a variant with a smaller cache. You have slightly finer grain control on a GPU, and very fine grain control on RAM or flash.
