Right
Where as on servers, these devices only offer a benefit of the CPU is
saturated and this permits for work offload, allowing the main system to
use CPU for other things.
Unfortunately, its often less expensive to buy more cores on production
servers than to put an $800 crypto card in.
But if you're doing lots of stuff on your AMD Geode appliance ...you may
find it beneficial.
That's why you see crypto card manufacturers getting into things like
HSMs and other products now, because the heyday of helping out a
Pentium-III server with a Crypto Accelerator is over.
