TLDR: CPU power refers to the computational capability and efficiency of a central processing unit (CPU) in executing instructions, performing calculations, and managing system operations. It is influenced by factors such as the number of cores, clock speed, architecture, and the presence of advanced features like hyper-threading or SIMD instructions. The evolution of CPU power has enabled significant advancements in fields like machine learning, gaming, and data processing.

Key determinants of CPU power include clock speed, measured in GHz, and the number of cores, which enable parallel processing of tasks. Modern CPUs, such as those from Intel and AMD, often feature multiple cores and threads, allowing them to handle multitasking and computationally intensive applications effectively. Technologies like turbo boost dynamically adjust clock speeds to optimize performance under varying workloads, enhancing the overall CPU power available to applications.

Architectural advancements like reduced transistor size and optimized instruction pipelines further enhance CPU power. Features such as integrated cache memory, hardware-level virtualization, and dedicated processing units for AI tasks or encryption also contribute to the CPU's capability. While higher CPU power improves performance, it often comes at the cost of increased energy consumption and heat generation, necessitating efficient cooling and power management solutions for sustained operation.
