I can’t wait for the same efficiencies we’ve seen in mobile CPUs to translate to other areas, like image sensors. The latest Sony a7s III is supposed to have a giant heat sink as one of its flagship features, but just imagine if they were working on TSMC 5nm tech.
Sensors such as CCDs are largely analog devices (up to the A-to-D converter), where thermal noise / shot noise etc. are things that matter. Cooling a CCD via active cooling or a heat sink will help lower the noise floor and improve the signal-to-noise ratio and thus picture quality.
My understanding is that higher density leads to greater noise. The prefer to use larger transistors that produce cleaner images.
