Good point, but this is based on a price ration. The ratio I am really
interested in is a performance ratio. so...
a quad 1.8GHz opteron ran a 12Gflop linpack. 1.8 is a bit outdated. A
2.4GHz should get ~16 Gflop. Compare this to the advertised 18Gflop for
the Orion box and adjust for marketing and they are about the same. So
your point is even better and the Orion box wins on heat/noise. Now for
On a side note, I have been waiting for something to happen on the low
power/more cpu for a while. It seems like there is a lot of room for
growth in that area.
