8 Device vs 16 Device RDRAM?

[Amused]

Googlegear has two different types of Samsung RDRAM. "8-device" and "16 device."

They have both flavors in ECC AND non-ECC.

What is the difference? Well, besides the 16-device being $5.00 more?

8 device is higher density.

16 device is slower, because each additional device adds latency to the RDRAM bus.

Hmmm. I wonder why it costs more?

The lower density RDRAM clocks much higher, however, which more than makes up for any increase in latency. If you want to do 533MHz to 590MHz FSB/RDRAM, get the 16-device RIMMs.
