1.4 ns or faster than 1400MHz...

Since we are getting closer and closer to the release of the R520 chip codenamed "Fudo", it is time to start wondering what kind of memory this chip might use. It's very easy to get the picture and you can just surf the web and actually see what kind of memory is available now.

What you can get at this moment is Samsung DDR 3, 1.4 ns memory, capable of working at an amazing 1400MHz. At this time the fastest memory clock used in graphic cards is 1180MHz, available for example on X850 XT PE cards. We know that these cards are using DDR 3 600 memory capable of working at up to 1200MHz so ATI is almost pushing the limits here.

Samsung even sampled DDR 3, 800MHz memory working at 1.2 ns to its customers but we doubt that ATI or Nvidia will use this. It will be rare and very expensive but will drive your card up to 1600MHz and some huge amounts of bandwidth.

This memory will be handy to power all the bandwidth greedy pipelines and make the solution as fast as it should be. You need a lot of bandwidth for 24 or even 32 pipelines, so therefore you need to use very fast memory such is this.

We are still unable to give you exact frequency numbers of memory that ATI or Nvidia plans to use but these are details that will be finalised just days before the companies' launch of its next generation latest and greatest cards.
