Carl, I need a refresher in RDRAM is DEAD, DEAD, DEAD 101. Why is this not an advantage for RDRAM? (From page 9 of the Intel slideshow: developer.intel.com )
----------------------------------------------
 

-- Current Dual Channel RDRAM platforms have cost adders
-- 6 layer boards, memory sockets, termination, etc.
-- Dual Channel RDRAM Platform cost reductions in progress
-- OEMs are already starting to cost reduce 2 channel RDRAM boards


                              PC133         DDR          RDRAM

Peak Memory BW               1 GB/s       1.6 GB/s      3.2 GB/s
# of memory sockets            2             2             2
# chipset pins (mem)         ~180          ~200          ~160
est. board layer count         4             4             4

est. board cost over PC133 sys ~$6 ~$7 (includes 10% PCB Zo)


-------------------------------------------
Also, one could look at Intel's plans for DDR P4 support as just a way to keep the RDRAM manufacturers honest -- as it is, they have Intel over a barrel with P4 requiring RDRAM. They also need the DDR chipset for server platforms and for the value segment.

Or, you could look at Intel's continued lip service to RDRAM as necessary for p4 sales, otherwise people would not want to buy a platform that is headed straight for the scrap-pile. How about sorting things out between these two scenarios?

TIA, wily
