The broadcom cards you mentioned are obsolete.

If so, it's not for any of the supposed reasons you mention above.
This is a completely different market; please take a grain of

The only justification these days I have for crypto is for embedded
devices that need accelerated crypto for VPN, and smart-cards or USB
crypto-tokens that protect RSA private keys from the host computer.

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
talk.  8-)
