The AMD Catalyst Center is a software suite developed by AMD (Advanced Micro Devices) that provides drivers and performance tools for its processors, particularly for NVIDIA GPUs. However, it's important to note that AMD and NVIDIA are two different companies, and Catalyst is a product of NVIDIA.
If you're referring to AMD's software, then the AMD GPU Driver (or AMD Radeon Software) is the equivalent of the Catalyst Center for AMD GPUs.
