>>715440120 (OP)Analog gold cables will have a better output assuming they are properly shielded and constructed since gold is a better conductor than the standard copper wires. So composite, component, svideo, or scart.
Digital cables like Hdmi though makes no difference. Unless the better conduction results in a higher bandwidth and whatever the devices are support that higher bandwidth for higher resolutions or bells and whistles like HDR or higher refresh rates. As far as I know the differences in hdmi standards between say 1.0 and 2.1 aren't related to material used, but I could be wrong. Two hdmi cables at 1.0 where one is non-gold and one is gold plated make literally no difference though.
