This may be true for Intel-based processors, but the progression from
EV4-EV5-EV56-PCA56-EV6-EV67-EV68 is quite radical for Alpha. The addition
of the new instructions on the latter generations (starting at PCA56) have
made a gigantic improvement for some operations. I don't know if this
applies to atlas or not since I don't know if any such optimisations have
been done for Alpha, but I figured I'd mention it from a non-Intel
processor family perspective. I'm sure similar may be true for other
processors as well.
