yes FGPIO is faster than the GPIO pins because the GPIO ports are accessed or connected to the VHB or VPB buses which has a range of 0-60 MHz clock while the FGPOI ports pins are to be accessed by Local busses nothing but the bus connected to the cclk which is 60 MHz. so the FGPIO are always faster than the GPIO.But when Pclk is 60 MHz, then FGPIO & GPIO are equal.
