Accessibility Inspector vs AMD Radeon GPU Profiler

Accessibility Inspector is Apple’s free macOS tool for examining accessibility information in app interfaces. It displays an element’s accessibility properties, available actions, and position in the view hierarchy. Audits identify common issues such as insufficient contrast, clipped text, and missing descriptions. Results can be saved as HTML reports containing summaries, screenshots, issue descriptions, and fix suggestions. Accessibility audits can also run in UI tests through performAccessibilityAudit(for:_:). The target menu includes apps on Mac and selected iOS, iPadOS, watchOS, or tvOS devices. Open it from Xcode through Xcode > Open Developer Tool > Accessibility Inspector. Apple’s listing describes Xcode as Mac-only, requiring macOS 26.2 or later and an Apple M1 chip or later, and labels it Free. Clearing reported issues does not prove complete accessibility; Apple recommends additional checks with assistive apps such as VoiceOver.

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.
