Iron, RAM, and the truth ..?

Question

Iron

For example, there is one computer and 2 sets of RAM:
1 set: 4 sticks of 4GB = 16GB
2 set 1 stick of 16 GB
Both sets operate at the same frequency (let it be 1600 MHz)
Question: is it true that the 1st set will work faster than the 2nd?
It seems to me yes, because the throughput there will be 4 times higher.
The question arose because the one and the bus frequency is 1600, which means the bandwidth of the 1st set (1600 * 4 = 6400 MHz) will not be so important

Answer 1

However, only not in 4 times.
