How has processor speeds changed over the past decade?

Over the past decade, processor speeds have evolved significantly, primarily driven by advancements in semiconductor technology and architecture. While traditional clock speeds have plateaued, leading to a focus on multi-core designs and parallel processing capabilities, improvements in efficiency and performance per watt have allowed processors to handle increasingly complex tasks. Additionally, innovations such as 7nm and 5nm fabrication processes have enabled more transistors to be packed onto chips, further enhancing performance without a proportional increase in power consumption. Overall, the emphasis has shifted from just speed to a combination of speed, efficiency, and overall processing capability.
