It would be interesting to see how much the low power Intel chipset, that uses DDR2-800 opposed to FB RAM, does with these CPU's. I suspect that close to 25% of idle power is the FB RAM power consumption so the DDR2-800 should help significantly....

I beleive this is the Seaburg chipset.

It's only reasonable that if you buy low power CPU's, at a premium, you also will go with the rest of the low power package....


Neal, can you add a few lines to your comparative analysis of Intel and AMD processors, with Intel using the 5100 chipset that has plain registered DDR2 support?

It would be interesting to include a measure of the energy required to get a particular job done. This should be better at showing power advantages in non-idle situations, I think.

Could you add a line to your table with a 2.0 Ghz AMD based machine?

At what wattage do these quads become eligible for laptop duty? I am very interested as to when that happens. And what the wattage numbers would be in laptop form.
