I disagree, as far as transistor density it's not completely dead. Looking at the following logarithmic graph there's an inflection point around 2005, it slowed down but it still looks like we're on an exponential growth path.

It feels odd that that graph includes some CPUs with integrated GPUs, but otherwise only focuses on CPU transistor count. I wonder what a graph of 'biggest/mean/median retail CPU + dedicated GPU combo transistor count' would look like - presumably the graph would be a decent amount steeper?

I definitely think counting GPU as part of the compute package makes sense given how much of modern computing is now delegated to it outside of just rendering.

There's no cost on your graph, so you don't know what is the most economical package.

The fact that the width of the distribution became so much larger after that inflection is evidence against your point. Your graph points suggestively into Moore's law being dead.

(But we do know it died when fabs started making 3D transistors. No need to look at suggestions.)
