Well, generally speaking, we, consumers, don't. CPU performance has been stagnating for some time, and nobody has really cared much. In fact, rather than people moving to platforms that offer better performance, there has been been an active migration away from higher power platforms, to laptops, mobiles and ultimately cell phones.We, consumers, do not need faster CPU?
I spoke to an Intel CPU engineer 5 or 6 years ago, relatively new at the company. When questioned regarding the need for higher CPU performance, and the challenges of selling new kit based on performance, he put forth an argument of faith - he assumed that important new software would evolve that justified the effort and expense spent on increasing their x86 performance.
He was wrong. It didn't happen.
As we now start to see cell phones being able to connect to the cloud when asked to do serious computational heavy lifting, client (consumer) side CPU performance is destined to mainly evolve towards lowered expense and less power to allow broader applicability and better ergonomics. In fact it already happened. x86 is a dinosaur driven by market inertia. All of this is not to say that there aren't specific areas where CPU computational power is relevant. My own field, for one, can use as much as anyone can supply for the foreseeable future. But consumers? The killer app never materialized.
