Notice these are "small systems" only, i.e., graphics cards.
This is not of much interest until we get real production DDR PC systems. So far we have DDR vaporware from the AMDroids.

Hi Scumbria; Re ratio of RDRAM to DDR systems...

It seems to refer to systems in production and sold with a distinct name to consumers.

The vast majority of the RDRAM systems listed are i820 or i840 motherboards. All the DDR systems are GeForce or GeForce2. If you count by chipset support, the ratio would be considerably below the "7" I gave.

It's kind of a silly way to measure use, as the PS/2 only gets one mention, while the i820 gets 40 or so. Thus the actual use of the product is way out of proportion to how many times a chipset is mentioned in the list. It would be better to show actual chipsets, available in finished form to the consumer, in which case the ratio would be something more like 3 or so. Some graphics houses other than Nvidia are putting out DDR based boards, they should be on the list in a month or so. But among the DDR graphics users, only Nvidia sells lots of chips to other companies, and so they are the only one that generates a lot of line items (i.e 10).

Since DDR is much more suited to low volume production, (for instance, Altera and Xilinx both sport intellectual property support for DDR but not RDRAM,) the metric Dramreview used will show a longer list for DDR than would be proportional to the chip usage. When the DDR systems start shipping in volume to consumers DramReview will drop the product count, or at least modify the metric they are using to keep count. Their website is not intended to provide unbiased information. My guess for them dropping the issue is late 4Q00. When it happens, I will refer back to this post...
