What is it ? > >Mathieu 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...
