On the manufacturer side the chips are also smaller, which means more chips per wafer (and thus, presumably, more yield/profit), correct?

- dougmwne 4y agoThat is offset some by higher defect rates in newer and smaller processes and ever increasing manufacturing costs per wafer. But the metric that matters is cost per transistor. Historically that was always dropping, but more recently it may be flat for some nodes, increasing temporarily or just not dropping as fast as the historical trend.
