Litwr: most games don't use full time processing that depends on CPU clock speed but - as Gaia mentioned - to avoid screen flickering they sync every action to screen refresh. And that is faster on NTSC machines. For example there is a raster interrupt at the bottom of the visible screen and the interrupt handler queries the controls (either joystick or keyboard) moves the sprites, refreshes the screen, plays music and does everything else that is needed.
