From the Anand thread:forums2.anandtech.com Bilow Junior Member Date Posted: Dec/23/2000 12:31 AM "PC2100 is a marketing term. Get real. This is 266MHz memory. Look at ANY memory benchmark comparison between RDRAM on an i850 system and any DDR PC266 (aka, "PC2100"), using STREAM, LINPACK, or Sanda Memory benchmark. If you take the marketing at face value, PC2100 should be able to perform within 65% of dual-RDRAM channels (2.1/3.2). It doesn't even come close--maybe 40%. Go read up on DDR-SDRAM as main system memory. Read even the older Anandtech pieced. There is a little piece of information there you need to commit to memory: The data lines are double-clocked. The address lines are not. DDR's inherent latency, and inherent ability to transmit data is the same as SDR-SDRAM. The other thing you overlook is how many pins it would take to implement a dual-DDR chipset. DDR already inflicts a 100-pin penalty (on the northbridge) relative to SDR-SDRAM. And you want to double that? Gigabyte/MicronPC had to halt shipments of their AMD760-based systems while the redesigned the motherboard, going from 4-layer PCB to 6-layer. And you want to double the pin penalty? DDR is simply an attempt to design around patents. It's a pretty bad one--SLDRAM (another Micron initiative) was better, but their lawyers told them that they would lose in court, so SLDRAM is dead. DDR-II will just be the latest attempt to get around the patents, assuming Micron is still in business. I'll make a side bet--when Sledgehammer ships, it will use RDRAM, not DDR. Because RDRAM delivers." This gets curiouser and curiouser. LOL. BP
