KZNerd,

But can you imagine the gall of the person who posted this: "One-half the power of a comparable PC100 SDRAM system" on their website?
rambus.com


That looks a very reasonable claim by Rambus on their website. After all, they are referring to system power consumption, not the maximum power consumption of individual chips.

Bilow was comparing individual chips (and perhaps using old data). However, in a single channel Rambus system only one chip will be operating at full power at a time, whereas with SDRAM 8 chips will be turned on simultaneously for a 64 bit read (assuming 8 bit chips).

So even if the power consumption of individual Rambus chips is a little higher when active, the system power consumption can be much lower.

This also means that a Rambus system places fewer peak current demands on the power supply, allowing lower cost regulators and lower value decoupling capacitors, thereby saving money.

This explains why Rambus refer to a heat spreader on the RIMMS rather than a heat sink (although it is this of course).
