ISTR an article comparing Xeons and Athlons with DYNA... ah:
By that report, the Athlon 1800 beat out a 2GHz Xeon by a decent margin.
Of course, we don't know what type of sim that was -- if memory bandwidth
comes into play, the Xeon may take the lead again. Your best bet may be
to contact LSTC and/or find some systems to benchmark.
Note that I only have experience with DYNA on single nodes -- I haven't
played with mpp-dyna yet.
