If so, it's not for any of the supposed reasons you mention above.

There are many such embedded/small-CPU devices (not just for VPN, mind
you) that need low power consumption, which is certainly not an
amd64-type-CPU strong suit. A CPU of the power you mention is a *very
very bad* fit here; typically these machines are 486 or Pentium-II
generation at best. It's like comparing pears vs. tangerines, or
something like that.
Now, show me a complete amd64-based machine in the ballpark of the
speed you mention, using less than 2A of current @ 5VDC, and we'll
