The CPU is a processor under the von Neumann architecture, where instructions and data must be accessed from the same storage space and transmitted via the same bus, which prevents overlapping execution. This process determines that the CPUis good at decision-making and control, but is less efficient in multi-data processing tasks.

Generally, the improvement of CPU computing power relies mainly on two aspects, namelyclock frequency and core count. The operations of a computer are executed step by step under the control of clock signals, completing one operation per clock cycle. The level of clock frequency largely reflects the speed of the CPU. The CPU core is a single processing unit within the CPU that can execute instructions.

Typically, the higher the clock frequency and the more cores, the stronger the CPU performance, but this also brings aboutexcessive power consumption and overheating, which, if the cooling cannot keep up, may lead to CPU damage.

As CPU computing power gradually reaches a bottleneck, it increasingly fails to meet the exponentially growing demand for computing power. The direction of computing power development is increasingly shifting toward specialization, seeking higher performance, lower power consumption, and cost.

GPU (Graphics Processing Unit), as the name suggests, is primarily responsible for performing image and graphics-related computations.
