True, but in terms of memory bandwidth the opteron is very good, and
hypertransport allows them to pop fpga's and other custom logic chips
into cpu sockets and have amazing acess to the main cpus and memory at
quite low cost. After all if you can turn your key calculation into a
hardware operation in an fpga, a general purpose cpu generally has no
hope of competing.
