S. Plakhov ; A. I. Shevtsova ; O. O. Ulyanova ; A. A. Skoryk ; V. N. Tkachev // YSF 2015 - International Young Scientists Forum on Applied Physics 29 Sept.-2 Oct. 2015, Kharkiv, - 4 p. DOI: 10.1109/YSF.2015.7333253http://openarchive.nure.ua/handle/document/4692The article shows the limits in the processing speed which are achieved by the modern graphic cards of the NVIDIA type. It also considers the level of the computational errors that registered with FFT and inverse FFT at different plans for their implementation and lack (the absence) of distortion type jitter. A comparison of the speed of the spectral data analysis using different plans and different drivers was carried out on three types of graphic cards NVIDIA GeForce GTX 210, 660M, 680. Also the comparison of the speeds and the processing errors was carried for the mentioned graphic cards and CPU Intel Core I7. Some inconsistencies were found in the recommended technical documentation, which is given on the official NVIDIA website, with parameters of the really (actually) working FFT and inverse FFT plans.enNVIDIAFFTConference proceedings
