Hi milo_morai; Re power consumption and RDRAM... It ain't so simple.

Problem is that you can arrange for fewer RDRAM chips to be active at any given time.

The issue is really a lot more complicated than would be indicated by most of the people commenting on it. Suffice it to say that RDRAM didn't find its first big use in battery powered equipment.

Another comparison would be the 2Mx32 DDR chips used in graphics with the least power consumption RDRAM chips. The bandwidths per chip are reasonably similar, but I bet that the DDR chips use a less power than any RDRAM chip.

On the other hand, there aren't any next generation 64Mbit RDRAM chips to compare those 2Mx32 DDR chips to. So the comparison is a little unfair.

But overall, I have no doubt that RDRAM uses more power in most systems. That's why they are the first (recent)
DRAM system to have so much literature devoted to cooling.

RMBS just traded through $165. Got to be a good bounce around here somewhere.
