Dead end
Dessau: "the speed of the processor no longer determines the experience of the end user"
This guy is delusional. Just because it costs more than ever to develop a new manufacturing process that makes chips faster does not mean users do not want faster processors. I, for one, want a CPU that is 10 times faster. I do not want 10 slow CPUs on one die as a substitute.
Previously, part of the profit generated by selling older generation chips went to subsidise the development of faster, newer generation of semiconductors. It may seem sub-optimal to a marketing person like Dessau, obviously he wants to concentrate on profit generation, not development, but let us see where this fab-lessness leads.
The costly process development is outsourced to The Foundry. Why would The Foundry want to spend billions upon billions of $ to create a process comparable to the latest Intel or IBM process? It is not where the profit lies. The most profitable are one-generation-older chips, I think. So a design company like AMD would not be able to make a CPU faster than Intel's, unless AMD pays same billions to The Foundry for development. If it does not, it would have to design chips using old technology. This would mean an end of AMD as a competitor to Intel on the "fastest CPU" market. We'll be stuck with Intel's monopoly.
