No, you have it correct.  athlon-64 at 2.4ghz is about 10% faster than a single
opteron at 2.2ghz.  Of course, the single opteron 875 actually has two cpus on a
single chip, so it is almost twice as fast as your one processor athlon-64.

See my other post with some actual search speed data from my xeon and opteron
runs...
