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

Analyze Test Configuration:

VkFFT 1.1.1

OpenBenchmarking.org metrics for this test profile configuration based on 406 public results since 16 December 2020 with the latest data as of 23 July 2023.

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.
