What OpenCL-Benchmark is

OpenCL-Benchmark is a small program for measuring peak GPU and CPU performance on Android, Linux, macOS, and Windows. Its compute tests cover FP64, FP32, FP16, INT64, INT32, INT16, and INT8, while memory tests measure coalesced and misaligned reads and writes. PCIe tests measure send, receive, and bidirectional bandwidth, then estimate the PCIe generation on the assumption of an x16 link. You can pass device IDs to limit a run to selected hardware, and the program supports command-line use and automation. Build instructions cover Visual Studio on Windows and make.sh on Linux, macOS, and Android. The software is free. Its license permits educational use, non-military research, and non-military commercial use, subject to attribution and marking modified versions; attribution is required in product documentation when used in a product. The license also disclaims warranties and provides the software as is.

Good

  • Measures seven compute data types.
  • Tests memory reads and writes.
  • Measures PCIe bandwidth in three directions.
  • Supports selected device IDs and automation.
  • Free for permitted uses.

Watch out

  • No free trial is listed.
  • Product use requires documented attribution.
  • Modified versions must be marked.

Who it suits

It suits people comparing GPU or CPU compute and memory performance across supported systems. Users planning to include it in a product should note the attribution and modification-marking conditions.

Verdict

OpenCL-Benchmark covers compute, memory, and PCIe measurements, with device selection and command-line automation. Its license conditions and warranty disclaimer are worth reviewing before use.
