Boards for Fastest Intel Processors

[Craig Tierney]

Not sure on the availability.  Even if I did know, it would
be NDA.  The serverworks chipset, Grand Champion HE, looks very
promising.  PCI-X, uses DDR-RAM, had 6.4 GB/s memory bandwidth.
The i860 chipset has 3.2 GB/s.  Each P4 and Xeon is said to
drive 3.2 GB/s.  If Supermicro puts the HE chipset on the dual
board which I think is going to happen I am going to drool.

The current Xeon at 1.7 Ghz puts up a great fight with Alpha 
833 Mhz chips when you use the right compiler.  Performance of
the Xeon is only about 20% slower but at 1/4 the cost.  Increased
cache and the increase in the memory bandwidth for the P4 in a dual setup
will be better for my codes than Alpha.  Your codes may vary.
