wild guess on performance of dual DDR at 200MHz??

does anyone have a wild guess/est. 'bout the performance of dual DDR at around 200MHz?? say Sandra memroy score. what to expect?? around 4000 mark?? higher/lower??

just need a rough guess of it so i could decide whether to wait for the dual DDR hoping it runs at 200MHz or stick w/ 160 (or so)MHz x 4 RDRAM.

4700-5400mbs in sandra would be my guess for 400ddr speeds.
In theory it could be 6400mbs but that would require 100% efficiency.

4700+?? that's more than a RDRAM at 165+x4!!!

if so, i guess i'd better wait for the dual DDR than go ahead for RDRAM.

Yeah... I mean some overclocked higher quality DDR is beating pc800, so even at 75% eficciency, double that will beat RDRAM.
RDRAM's days are numbered.
