OpenCL-Benchmark review
A focused, free OpenCL benchmark for compute, memory, and PCIe measurements.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenCL-Benchmark is a free, open-source command-line benchmark for measuring GPU and CPU performance through OpenCL. It is intended for developers, hardware testers, researchers, and technically oriented users who need local measurements of compute throughput, memory bandwidth, or PCIe bandwidth. Its desktop and mobile deployment targets cover Windows, Linux, macOS, and Android, making it suitable for users working across those platforms.
The benchmark’s strongest area is workload coverage within OpenCL. It tests FP64, FP32, FP16, INT64, INT32, INT16, and INT8 compute performance, alongside coalesced and misaligned memory read/write bandwidth. PCIe testing includes send, receive, and bidirectional bandwidth. It also reports device, driver, OpenCL version, compute-unit, memory, and buffer-limit information, so results can include useful runtime and hardware context. Command-line device selection by device ID supports systems with multiple devices.
OpenCL-Benchmark fits users who want a focused, local tool rather than a broad PC benchmarking suite. Its open-source model and support for local compilation on Windows, Linux, macOS, and Android make the project adaptable to technically managed environments. The trade-off is its narrow OpenCL focus: it does not suit workloads that require broader application testing or benchmark coverage outside OpenCL-oriented compute and bandwidth measurements. Users comfortable with compilation, command-line workflows, and device identifiers should find its scope clear; users seeking a graphical, general-purpose benchmarking experience should choose a different type of tool.
OpenCL-Benchmark pros and cons
- Where it wins

- Measures memory and PCIe bandwidth in multiple directions
- Runs on Windows, Linux, macOS, and Android
- Where it doesn't
- Limited to OpenCL-oriented workloads
- Requires local compilation and command-line execution
- Focused on technically oriented benchmarking workflows
