If you do them in hardware, they always come bounded. At most n elements of size m bytes and both numbers usually single digit. If you want to lift that limitation, it usually is just as slow as doing it in software.

Unbounded queues are arguably not a good idea (although single digit bounds are possibly too low?), at the very least there would probably need to be some concept of back pressure.
