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.

Analyze Test Configuration:

VkFFT 1.3.4

Test: FFT + iFFT R2C / C2R

OpenBenchmarking.org metrics for this test profile configuration based on 186 public results since 18 February 2024 with the latest data as of 10 September 2024.

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 R2C / C2R) has an average run-time of 3 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.
