2x4gb is faster as it can operate in dual channel mode which is double the bandwidth.

As for adding RAM later there is always a risk that RAM not purchased as a single kit will not work properly. Usually ok if you get the same make and model or at least speed and timings but it’s not guaranteed. I have had issues mixing same make and model in the past.

Yes, the difference is with 2x sticks you can run dual-channel and essentially double your memory bandwidth. 1x stick will run single channel and gaming performance will suffer. Adding more RAM to what you have now is a gamble on if it will work correctly together or not. RAM is meant to run in a kit.

think of a single stick as a tank of water with 1 opening. no matter how large the tank is the amount that can pss the opening is limited.

dual channel would be having a large container of water and 2 openings for water to exit. the tank will drain faster than if it had one.
