Well, I'm not sure what's non disclosure and what isn't, but I'll
ask. The main benefit of PCIX is that it will allow Myricom to again
double their bandwidth, and it will allow significantly lower
latencies for tiny packets.

It's not clear that the Pentium III "Tulatin" cpus are ever going to
catch up to the Pentium 4 or AMD offerings. Unfortunately the Pentium
III currently has the best PCI bus implementations. However, if you
examine your applications, I suspect that you'll find that you aren't
maxing out communications, and that a mildly faster CPU is better than
a mildly faster PCI bus.

BTW there's a comparison of PCI bus speeds measured by Myrinet cards
