>Does anyone have a graph of recent $/transistor progress?
It wouldn't matter. You can't look at cost / transistor without factoring in Die Size and yield. Not to mention the cost of Higher Performance and Low Power Transistor are different. And the wafer price ( Cost / Transistor ) also exclude all the design cost and tooling around the node.
I'm interested in this as well. Of course from a practical POV, especially with escalating NRE costs at recent nodes, we're clearly at a point where "getting the same core size at lower cost" is not going to be a thing unless you can afford to amortize that NRE over a huge volume of chips.
