Go up one level in this thread
that formula doesn't work for all Xeons though. Xeon's IPC have shown to increase the higher the FSB increases. ie: The 400MHz 2.8 is slower than the 533MHz 2.8. Also, AMD's 760mp chipset is inferior to Intel's MP chipsets, but only in memory management. I would assume that with Junior's insane amount of kn/s, that it access the hash a lot and so therefore would have a slightly larger improvement as the speeds increase. Food for thought...
