Now available as part of the Radeon™ Developer Tool Suite.
Radeon™ GPU Analyzer is an offline compiler and performance analysis tool for DirectX®, Vulkan®, SPIR-V™, OpenGL®, and OpenCL™.
Download the latest version - v2.4.1
This release includes:
- Support for DirectX® Raytracing (DXR) in a new mode of the command line tool (
-s dxr):- Compile DXR HLSL code to generate RDNA™ 2 ISA disassembly, hardware resource usage statistics, live VGPR analysis, and control-flow graphs.
- The new mode does not require a raytracing-enabled AMD GPU. Installing the latest Radeon™ Adrenalin Software is sufficient.
- Improved performance in the GUI app to better handle shaders with large disassembly.
- Updated static analysis engine with support for the latest RDNA™ 2 instructions and bug fixes.
- Note: Legacy OpenCL™ mode of the command line tool (
-s cl) was removed in this release. OpenCL support for RDNA™ would be added in the future in a new, offline, mode of the tool.
Inspect your ISA...
Analyze the ISA for your shader stages within a Vulkan® graphics or compute pipeline.
...compile for many products...
Select target GPUs for the compilation process. You can search for available targets by using specific GPU architecture or even retail product names, like “SSG” or “WX 8200”.
...refine your resources...
View register pressure and LDS/scratch memory usage for your target hardware.
...and correlate your code!
For OpenCL™ kernels, the tool provides correlation from high-level source code to the disassembly, and from the disassembly to the high-level source code.
