Re: <I'll see if I can get a defintive answer to that question.>

If it supported both equally well then we'd finally have a definitive answer on drdram performance in real systems head-to-head against sdram. Wouldn't that be great?

Paul,

The HUB you described would have to fit into a RIMM connector, translate the 400 MHz double pumped DRDRAM protocol into SDRAM protocol, and communicate with 100 MHz SDRAM's.

This device would by necessity be rather complicated, and would have to test at 400 MHz. When did they start designing this hub? The problems Intel will face are:

1. Time to market.
2. Yield with a 400 MHz bus.
3. Performance.

#3 sounds particularly difficult because the DRDRAM banks behave differently from SDRAM banks, meaning that complexity/performance compromises will have to be made.

Intel has a tough row to hoe getting these HUBS into the market.
