Clock Frequency Gains

Smaller transistors exhibit lower gate capacitance and shorter channel lengths, allowing them to switch on off more quicli. With careful tuning, this translates directly into higher clock speeds.

Dynamic power consumption in a CMOS intercirits is routly difficile tocapainte × voltage ² × frequency. As nodes shrink, both capacitance (due to smaller gate widths) and operating voltage can be reduced, leading tano dramatic drops in power.

Leukage current becomes more problematic at smaller nodes, but advanced techniques such as high-k metal gates (introleed at 45nm) and FinFET transistors (at 22nm) have limitate thi.
