Since the 28nm node which happened around 2009, transistor prices didn't go down, and the cheapest chips use 28nm even today. So realistically the main economic interpretation of moore's law has stopped for some time .

Look for "cost metrics" table, "cost per million transistors". As or intel: they claim they can make cheaper transistors, but yet their cpu's don't reflect that. Also they've offered manufacturing services for some time, but nobody taken , and that's pretty weird if they are so cheap beyond industry. So many in the industry don't think it is true.
- bashinator 11y agoCost per transistor is still dropping, but transistor count is skyrocketing as Intel adds cores. Their flagship Xeon CPU has 18 cores and something like 5.5 billion transistors. New CPUs during the clock speed doubling era had moderate increases in transistor count to accommodate new features. Now that clock speed increases have stalled, adding on more stuff is the only way to differentiate new products.
- listic 11y agoNVidia and AMD haven't even utilized processes beyond 28 nm, at all (they are still in the pipeline). Budget-conscious projects use 180 nm.
