Infinity Cache is a high-speed memory technology developed by AMD for its RDNA 2 graphics architecture. It acts as a large, fast cache that sits between the GPU and the main memory, significantly improving data access speeds and reducing latency. This allows for better performance in gaming and graphics-intensive applications. By using a smaller amount of high-bandwidth memory, Infinity Cache enhances the overall efficiency of the graphics card. It enables higher frame rates and better visual quality while consuming less power, making it a key feature in modern graphics cards designed for gamers and content creators.
