Trends in processor count and memory growth

Of late system address space has been growing at a rate of between 1 and 1.5 addressable bits per year. Interestingly, though, we're now adding processors to systems faster than we're adding memory. That is, processors/GB RAM is currently increasing. If that trend holds true and programming models remain the same, then, arguably, synchronization will become even more important as more processors will be coordinating access to a given amount of memory. Proper fine-grained orchestration will become even more critical.

I'm curious - for how long has this trend held?
