AMD Radeon GPU Profiler vs MicroProfile

AMD Radeon GPU Profiler (RGP) is a free low-level optimization tool for examining workloads on AMD Radeon GPUs. AMD positions it for PC game developers and developers optimizing applications for AMD RDNA hardware. It analyzes graphics and asynchronous compute usage, event timing, pipeline stalls, barriers, and bottlenecks. Frame and queue views show command-buffer submissions and interactions among graphics, compute, and copy workloads. Wavefront analysis links wavefronts to launching GPU events and displays cache information, while instruction timing reports average latency for AMD RDNA instructions to help locate shader hotspots. RGP supports DirectX 12 and Vulkan graphics, plus OpenCL and HIP compute. It runs on Windows 11 and Ubuntu 24.04 LTS, with Linux limited to Vulkan. Version 2.7 is dated June 2026. Older APIs such as DirectX 11 and OpenGL are unsupported.

MicroProfile is a free, embeddable C++ profiler supplied in a few files for adding profiling to a project. Developers mark code with timer macros and include microprofile.cpp. Its live view is opened in Chrome by visiting the profiler host on port 1338, and it can capture the last 30 frames by default. Captures are self-contained webpages that can be saved and shared; profile data can also be written to HTML or CSV. GPU timers support OpenGL, D3D11, D3D12, and Vulkan. Counters appear in live and capture views, and timeline markers cover longer-running unique timers. A detailed view can compare two captures, but not captures made with earlier versions. Experimental dynamic instrumentation supports Intel x86-64 on Windows, macOS, and Linux, with MICROPROFILE_DYNAMIC_INSTRUMENT_ENABLE and distorm required; Linux builds also need -rdynamic. Default per-thread profiling buffers allocate 2 MB, and GPU buffers default to 128 KB each. The project is MIT-licensed and lists Windows, macOS, Linux, and unspecified console support.
