Meet the Radeon™ GPU Profiler, a ground-breaking low-level optimization tool that provides detailed information on Radeon™ GPUs.
| DOWNLOAD - Latest version 1.7
This release adds the following:
- Support for Radeon™ RX 5500 and Radeon™ RX 5300 hardware.
- New Pipelines Overview pane to summarize pipeline usage for the profile.
- Pipelines and Pipeline state views will indicate if a shader was compiled using wave32 vs. wave64 on RDNA hardware.
- In the Barriers pane, additional cache levels (L0/L1/L2) are shown for invalidates on RDNA hardware.
- The Most Expensive Events and Render/Depth Targets panes now have sortable table columns.
- The Frame Summary and Profile Summary panes now show the amount of profiling overhead (the amount of video memory and bandwidth consumed by profile data collection)
- Add Overlays in the Wavefront Occupancy Event Timeline view to view User events, Hardware contexts, Command buffers and Render targets.
- Improved Instruction Timing to increase accuracy of timing data.
- Improved zoom control UI in the various panes that support zooming.
- Improved UI when running at different DPI settings.
- Bug/stability fixes.
Unlike the black box approach of the past, PC game developers now have unprecedented, in-depth access to a GPU and can easily analyze graphics, async compute usage, event timing, pipeline stalls, barriers, bottlenecks, and other performance inefficiencies.
This unique tool generates easy to understand visualizations of how your DirectX®12, Vulkan®, and OpenCL™ applications interact with the GPU at the hardware level. Profiling a game is both a quick and simple process using the Radeon™ Developer Panel and our public GPU driver.
Figure out your frame
Get a bird’s eye view of how your command buffers got submitted to each GPU queue.
Understand how your graphics, async compute, and copy workloads interact and synchronize.
Wade through your wavefronts
Undestand how your wavefronts were pushed through the GPU. We can also correlate between wavefronts and the GPU events which launched them.
The data displayed in this view is highly filterable, groupable, and includes a side panel with added detail about user selections.
Speed up your shaders
Quickly and easily find hotspots in your shaders using the instruction timing view.
Each instruction in your RDNA ISA has a bar showing its average latency, allowing you find the right things to optimize.
Banish those barriers!
Find out which barriers flushed caches, caused a synchronization point or even ran their own, internal shaders.
Burst those pipeline bubbles and claim back your performance.
