clpeak vs Parkdale

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.

Parkdale measures read and write speeds for hard disks, CD-ROM devices and network servers. Its three access modes offer different ways to run a drive test. QuickAccess checks sequential and random access with 4KB blocks and 32 concurrent threads. FileAccess reads and writes test data in a regular file through the filesystem; BlockAccess works directly with disk sectors and displays transfer rates over time. Users can compare and submit drive results on the Benchmark page. The Windows version has command-line options for the drive, file size, block size and log-file creation, and installation is available through winget and Chocolatey. Parkdale runs on Windows, macOS and Android, with the maker listing operating systems from Windows 11 through Windows 98, macOS 27 through 10.7, and Android 12 through 4.4. The free software is supported by donations. The maker says crash reporting and automatic update checks can be disabled; those functions send a unique non-personal ID and operating-system version, and IP addresses are recorded to distinguish usage countries.
