Basemark GPU vs clpeak

Basemark GPU is a graphics benchmark for comparing performance on mobile and desktop devices. Its proprietary C++ Rocksolid engine runs the same workload across platforms, while the graphics API varies by device: Android supports OpenGL ES or Vulkan, iOS and macOS use Metal, and PC and Linux can use OpenGL, Vulkan, or DirectX 12 when supported. High Quality targets desktop graphics and Medium Quality targets mobile graphics; their official offscreen resolutions are 3840×2160 and 1920×1080 respectively. The game-like scene can generate tens of thousands of draw calls per frame. Results appear in the Powerboard for comparison. The free edition sends results there automatically and provides a single score without breakdown analysis; it requires internet access and is limited to home or private use. Basemark GPU is available for Windows, Linux, macOS, Android, and iOS. Its Corporate edition is for commercial use and adds full test details, custom configurations, automation, data export, and optional result submission. Pricing for that license is available by request.

clpeak is free GPL-3.0 software that benchmarks peak compute throughput, memory bandwidth, and latency on CPUs, GPUs, and NPUs. It runs the same tests through available device APIs so results can be compared between machines. Coverage includes compute, matrix engines, vendor libraries, bandwidth, latency, AI workloads, and CPU-specific operations. GPU backends include CUDA, ROCm/HIP, Metal, oneAPI/SYCL, Vulkan, and OpenCL; AI runtimes include ONNX Runtime, Core ML, and LiteRT. The app detects devices, streams measurements, and keeps renameable run history that can be exported as JSON. Its CLI selects devices, backends, and test categories, describes measurements, saves JSON runs, and compares saved runs. It runs on Windows, macOS, Linux, iOS, and Android. Releases include platform archives, a macOS DMG, Snap distribution, and Google Play availability.
