CDNA architecture refers to a design framework used in computing, particularly in graphics processing units (GPUs) developed by AMD. It focuses on optimizing performance for data-intensive tasks, such as gaming and machine learning, by enhancing memory bandwidth and efficiency. The architecture incorporates features like Infinity Cache and improved power management, allowing for faster data access and reduced latency. This results in better overall performance and energy efficiency, making it suitable for high-performance computing applications and modern gaming experiences.
