VkFFT

VkFFT is a Fast Fourier Transform (FFT) Library that is GPU accelerated by means of the Vulkan API. The VkFFT benchmark runs FFT performance differences of many different sizes before returning an overall benchmark score.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark vkfft.

Performance Metrics

VkFFT 1.3.4

Test: FFT + iFFT C2C 1D batched in single precision

OpenBenchmarking.org metrics for this test profile configuration based on 242 public results since 18 February 2024 with the latest data as of 24 January 2025.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.

Based on OpenBenchmarking.org data, the selected test / test configuration (VkFFT 1.3.4 - Test: FFT + iFFT C2C 1D batched in single precision) has an average run-time of 4 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.

Notable Instruction Set Usage

Notable instruction set extensions supported by this test, based on an automatic analysis by the Phoronix Test Suite / OpenBenchmarking.org analytics engine.

This test profile binary relies on the shared libraries libvulkan.so.1, libm.so.6, libc.so.6.
