looking at number alone, its 3x, but alot of time, number like that doesnt mean anything, it really depends on what you are using it for.

ie

if you mainly using it to download big files, then the number matters, it cut down your download time to 33%

if you use it to browse simple webpage, its not going to be matter even its 3 times faster loading like 0.33 second vs 0.31 second (assuming 0.3 second is the bottleneck of speed of light or the fiber cable, even you go 1 billion times faster, you cannot reduce this 0.3 second until we human figure out how to beat speed of light).

then gaming, i havent seen any game need that much bandwidth YET, but it might exists soon after 5g widespread, but if you do stream your game(let other watch), then its another story, you will need high bandwidth for real time streaming, 1080p60 require like 10mbps, 1440p60 require 20mbps, to do 4kp60, you will need like 50mbps. technically more will be better as the streaming wont lag your game(if your game also required internet, playing game while internet is bz will lag)

lastly watching youtube 4K p60 required upto 50mbps, but if you only have fullhd monitor, forget it.

all calculation assume you are the only user using the line, if you have few other ppl that might use the line, do consider them.
