clpeak vs Filebench

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.

Filebench is a Linux file system and storage benchmark for generating workloads and measuring I/O behavior. It supports micro- and macro-benchmarking, with random and sequential tests, IOPS measurement, and latency measurement. Its Workload Model Language (WML) lets users describe application I/O by defining filesets, processes, threads, and flow operations. Built-in workload personalities cover mail, web, file, and database servers, and predefined examples include webserver, fileserver, and mailserver workloads. Shipped workloads may not match a particular system's scale, so the documentation recommends copying and adjusting them. Filebench is free: its listed plan is free, with no usage limits stated. It runs on Linux and provides a command-line interface. The README describes building and installing it with configure, make, and sudo make install; yacc and lex are required. Questions, bug reports, and feature requests go to GitHub Issues. The project uses the Common Development and Distribution License (CDDL), Version 1.0.
