Is there a faster random number generator than the standard rand()?

Question

C++ / C#

I need a faster option than the standard rand function.
I think there must be something faster, whether in C or C++.

Answer 1

I remembered:

But seriously, it depends on the task: you need to get real random numbers, or just create a feeling of randomness in the user.
The fastest will be the non-random random, which simply returns a number and a predetermined sequence.
The slowest is a real random based on some kind of physical effect. (for example, throwing a die)
