You're making the assumption that such a chip would reach market at the same time and in the same condition. The existing chip design companies are, in fact, really good at what they do, and they are rushing these things to market about as fast as can be done. Hardware product cycles are much longer than those for software, especially if you are trying to "innovate" like you posit. You can't just rev a new chipset for ever device release.
