This price differentiation actually occurs in all products and companies. Look at SaaS, it's all the same software product but features are selectively enabled for higher-paying customers. Something that's different between software and hardware such as chips are that the chips that have things disabled are done so because those disabled parts actually don't work. If you only yield 2 out of 4 cores, it's easier to just make it a dual-core CPU rather than throw the chip away.
