When it was released, Niagara definitely had an edge. I don't know how well it would fare today.

I mean that the benchmark itself is very complex. Simply measuring performance is non-trivial, but measuring performance and power is much much more complicated.

Small things like the # of fans in a system suddenly make a much larger difference.

I agree the results look a little empty, nothing from HP, IBM, Sun or Fujitsu with their proprietary systems.
