Speed & Bandwidth is in reality the exact same thing. Speed could actually mean low bandwidth but a very high speed. Using VOIP for a phone call over the internet is a good example where speed is more important that bandwidth. Even if you only had a 2mb connection over ADSL, that could actually work better than 20Mb connection over 3G.

That detail aside, what matters most is what a change to Fibre could mean in real life:

Say you wanted to download an 800mb file with a 2Mb connection;

-       that would take you (theoretical best case in all examples) approx 55 min’s

If you had Fibre300, then things would be different;

-       that would take you (theoretical best case in all examples) approx 22 seconds

If you have kids that wants to download that fantastic new game from the PlayStation Store,

“Its’ only 10 euro and 7 GB after all, and you can download it directly on the PlayStation.”

With an 8mb connection, you’d be looking, in the best of worlds,

-       that would take you (theoretical best case in all examples) approx 2 hours

If you had Fibre300, then things would be different;

-       that would take you (theoretical best case in all examples) approx 3,5 min’s

In real life, you would probably never obtain any of these max theoretical speeds. This as the speeds on different sites, different download will differ themselves. It is however no denying that it will be noticeably faster than anything you had before and that everyone in the household can be using simultaneously without creating delays and waiting time we all know too well
