Central processing unit (CPU) is the core component of computer, and its technological breakthrough and innovation plays a vital role in the improvement of computer performance. Over the past few decades, CPU technology has undergone a number of major breakthroughs and innovations that continue to drive computer development. First, the introduction of Moore's Law was an important milestone in the breakthrough of CPU technology.

       Moore's Law states that the number of transistors that can fit on an integrated circuit doubles every 18 months, while the cost stays the same. This means that the performance of the CPU will increase exponentially, providing a powerful impetus for the development of computers. By continuously increasing the integration of transistors, the CPU can accommodate more transistors at the same physical size, thus increasing the computational power.

       Second, the advent of multicore processors was an important milestone in CPU technology innovation. With the gradual failure of Moore's Law, the performance gains of single-core processors have encountered a bottleneck. To continue to improve the performance of computers, CPU manufacturers began to integrate multiple cores onto a single chip, forming multicore processors.

      Multicore processors enable multiple tasks to be executed simultaneously, increasing the parallel processing power of the computer and thus its overall performance. This innovation makes computers better able to handle tasks such as multi-threaded applications and large-scale data processing..Moreover, optimization of instruction set architectures is one of the important directions for breakthroughs in CPU technology.

      The instruction set architecture is the interface between the CPU and the software and directly affects the performance and energy efficiency of the computer. By optimizing the instruction set architecture, CPU instruction execution efficiency can be improved and energy consumption can be reduced. For example, the introduction of techniques such as superscalar, superbly, and out-of-order execution can improve the parallelism and execution efficiency of instructions and thus the performance of the CPU.
