Hi cordob; Re power dissipation. Yeah, I've been following the discussion, some of it is hilarious and I've copied it over to this thread. If RDRAM really did give great power consumption we'd have seen mobile applications from Intel already. Micron did pretty much the final word on this subject here, if you do a search of the net you can eventually locate the audio for the presentation that Micron gave on the subject. Their results are reported at this link from page 47 onward: images.micron.com If you desire to start making calculations from data sheets, (and want them to be taken seriously by the industry) I advise you to review the above to find out what is more or less expected of you. Power consumption in DRAM systems is incredibly difficult to calculate from the data sheets, so you are forewarned. An example of the subtle details is that a SDRAM or DDR memory system of a given size, made of chips of a given size (say 128Mbits, for instance), is more power efficient if the chips are as wide as possible. For this reason, mobile computers frequently use x16 chips while main PC memory (and the only DDR chip so far sold in the spot market) is x8. One should avoid accepting the power consumption figures of a certain company that was recently convicted of fraud, LOL. -- Carl
