Hexus has posted an DDR Technology article.
However, the advantages of DDR in games and geometry-intensive 3DRead more
applications are less evident. For the present at least, these tend to be more heavily dependent on cache speed and size, and on latency of the entire memory subsystem, than on bandwidth. This doesn't imply that DDR's extra bandwidth yields no improvements, merely that there are other potentially more important factors to consider. Since I believe this latter type of application that will be of more interest to hexus readers, the latency issue warrants further investigation.
