Scumbria,
Each channel of a DRDRAM system gives 1.6GB. Each connection to DDR gives 2.1GB.
sylvester wasn't talking about channels, he was talking about the P4. The P4 uses two RDRAM channels giving 3.2GBs of bandwidth. There have been no reports that I've seen of two-channel DDR systems or chipsets that support two channels of DDR. Likewise, there will not be any single-channel P4s. Therefore, it is misleading, when he's talking about systems that will only have 2 channels of RDRAM, to compare the speed of a single of RDRAM with a single channel of DDR and try to claim that the DDR system will have the greater bandwidth.
You weren't stating an opinion about a new subject, this is about a response to his statement. Either you misunderstood him (and forgot that the P4 had two RDRAM channels), or you were being intentionally misleading in your response. My guess is the former.
Alternatively, if you're going to switch to a new subject, you might want to point that out (to avoid misunderstandings <G>).
In any event, as you've indirectly explained in the rest of your message, from a system point of view, the DDR systems will be 2.1GBs (if they support DDR-II, otherwise 1.6GBs with DDR-I), versus 3.2GBs with P4 systems.
