-However from 2000 to 2010, single-threaded CPU performance growth was more modest compared to the previous decade (approximately 4 to 5 times). Clock speed stagnated due to a combination of power consumption, heat dissipation challenges, limitations in voltage scaling (Dennard Scaling[^3]), and other fundamental problems. Despite slower clock speed improvements, architectural advancements continued, including better branch prediction, deeper pipelines, larger caches, and more efficient execution units.

 From 2010 to 2020, single-threaded performance grew only by about 2 to 3 times. During this period, CPU manufacturers began to focus more on multi-core processors and parallelism rather than solely increasing single-threaded performance.
