vkpeak review
A free, open-source CLI for focused synthetic Vulkan device benchmarks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
vkpeak is a free, open-source command-line tool for measuring the peak capabilities of Vulkan devices. It is aimed at developers and technically inclined users who want synthetic measurements of compute and memory-copy performance, rather than a general-purpose PC benchmark suite. The available scenarios cover scalar and vector floating-point arithmetic, integer operations including dot products, matrix operations at multiple numeric precisions, and host-to-host or host/device memory-copy bandwidth. Results are printed in the terminal.
Its workload controls make it useful for targeted checks and scripted runs. Users can select a Vulkan device by ID, then run a single scenario, a comma-separated selection, or all available scenarios; CLI automation is supported. Downloadable executables are provided for Windows, Linux, and macOS, and the source can be built with CMake. The project description says builds target Intel, AMD, NVIDIA, and Apple GPUs, but useful measurements still depend on a system's Vulkan device and environment. This focused scope suits developers comparing specific synthetic Vulkan workloads across supported setups.
The main trade-off is interpretation: vkpeak is a synthetic benchmark, and it does not provide a comparison database, so users must assess results themselves or bring their own comparison process. Its terminal-oriented output and narrow Vulkan focus also make it a poor fit for buyers who want a graphical suite, broad real-world PC testing, or built-in result comparisons. For developers who need selectable arithmetic, matrix, and memory-copy tests across desktop operating systems, its free and open-source model is a straightforward fit; users seeking broader benchmarking should choose a more general tool.
vkpeak pros and cons
- Where it wins
- Tests floating-point, integer, matrix, and memory-copy workloads
- Runs on Windows, Linux, and macOS
- Select a Vulkan device and run chosen or all scenarios
- Where it doesn't
- Focused on synthetic Vulkan workloads, not broader PC benchmarking
- No comparison database is supplied
- Command-line results may not suit users seeking a graphical workflow
