AMD GPU Performance API (GPUPerfAPI, or GPA) is a powerful library, providing access to GPU Performance Counters. It can help analyze the performance and execution characteristics of applications using a Radeon™ GPU.

GPUPerfAPI is used by Radeon GPU Profiler, as well as several third-party tools including Microsoft PIX on Windows and RenderDoc.

GPUPerfAPI supports Vulkan, Direct3D 12, Direct3D 11, OpenGL and OpenCL on Windows and Linux.

Quote- Add support for additional GPUs and APUs.
- Add support for raytracing counters in Vulkan on RDNA2 (Radeon RX 6000 Series) hardware:
  - RayTriTests, and RayBoxTests: These counters collect the number of ray intersections for triangles and boxes, respectively.
  - TotalRayTests: This counter collects the aggregated number of ray-box and ray-triangle intersection tests.
  - RayTestsPerWave: This counter collects ray intersection test count at a more granular level – per wave.
