The GPU Performance API (GPUPerfAPI, or GPA) is a powerful library to help analyze the performance and execution characteristics of applications using the GPU.

This API is designed to:

  • Support Vulkan™, DirectX™ 12, DirectX 11, OpenGL, and OpenCL™ on GCN, RDNA, and RDNA2-based Radeon™ graphics cards and APUs.

  • Support Microsoft Windows® and Linux®.

  • Provide derived counters based on raw hardware performance counters.

  • Provide a fine-grained way to collect performance data for an application.
