clpeak vs Geekbench

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.

Geekbench is a cross-platform benchmark for measuring system performance across processors, devices, and operating systems. Its CPU benchmark covers single-core and multi-core performance in everyday application areas, while GPU Compute tests workloads including machine learning, image processing, and video editing. GPU tests support OpenCL, Metal, Vulkan, and CUDA. The free edition includes CPU Benchmark, GPU Compute Benchmark, and Online Results Management. Users can upload results to the Geekbench Browser and share them; accounts let them track results across devices. Benchmark charts aggregate results from real-user environments. Geekbench runs on Android, iOS, macOS, Windows, and Linux. Geekbench 7 Pro costs $99, paid once per user and adds command-line automation, standalone operation from portable storage or a network drive, and local result saving. Pro is licensed for commercial use. Support includes a community, email support, and a knowledge base. It is made by Primate Labs Inc., founded in 2004.
