Given the power of current CPUs, the special instructions some have to
accelerate crypto, and the overheads of getting to & from a crypto
accelerator, those devices may be useless in many cases. Certainly
they are rarely necessary.

The exception is a hardware RNG which is nearly essential in many
applications. Of course it is subject to almost undetectable attack at
the design/manufacturing level, so its output should be mixed with
other entropy.
