Once again, there are still transistor density improvements.

I'm not sure what you are trying to say here. Are you going back to saying computers aren't getting faster and then trying to say that moore's law is therefore dead when we've already established that it was never about speed?
Also what is your point about Amdahl's law? I work with lock free concurrency all day every day and if you are trying to say that more cores doesn't mean more speed because of Amdahl's law, that is pretty shaky ground to say the least. For some reason people seem to assume that if the software they use isn't using multiple threads effectively that it must be impossible. This is FAR from the case. Most programmers don't know how to work with concurrency and most software is trapped in legacy architectures that make parallel computations become painful changes.
> But Moore's law is an enabler of more sophisticated processor architecture.
Again, this tangential and not even really true. AMD's CPU architectures suffered while their GPUs performance and manufacturing process has remained competitive.
