AMD's CrossFire is a technology that allows multiple graphics cards to work together in a single computer system. This setup enhances the overall graphics performance, making it ideal for gaming and demanding applications. By combining the power of two or more AMD GPUs, users can achieve higher frame rates and better visual quality. CrossFire operates by distributing the rendering workload across the connected graphics cards. This means that each card processes a portion of the graphics data, resulting in improved performance. However, compatibility with specific games and software can vary, so users should check for support before setting up a CrossFire configuration.
