The Advantage Analysis of GPUs Based on CUDA

The development of computing technology has increasingly exposed the limitations of traditional central processing units (CPUs) and their architectures, especially handling data-intensive and highly paralleled computing tasks. This paper aims to analyze the advantages presented by graphic processing units (GPUs) based on Nvidia compute unified device architecture (CUDA). First, introduce the development background of GPUs, explaining the architecture conversion from specialized graphic processors to general-purposed parallel processors. The core research work takes a deep dive into the CUDA programming model, explaining its layered thread organization, memory structure, and software ecosystem. Then, a comparative analysis is conducted, detailing the outstanding advantages of CUDA-based GPUs over CPUs and other GPU methods in terms of performance, energy efficiency, programming flexibility, and ecosystem. In the end, the paper summarizes that the synergy between GPU hardware and CUDA software is the key driving force to break through modern computing bottlenecks and push forward the development of high-performance computing.
