Kap, re:RAMBUS article. Everyone was talking about
how expensive are the chips themselves, testing
expences, etc. However, the biggest caveat only
starts to surface:
"At IDF, system engineers were told that extreme care
is needed in laying out and manufacturing Rambus
motherboards. An NEC executive said PC makers
still don't quite understand where to place capacitors on the motherboard, and
how to deal with emission problems from the
chassis."

Note: an executive said "PC makers", which means
that the makers are at their own in board
development. It seems apparent that even
Intel has no clue how to deal with the
problem of 800MHz data switching while
providing memory expandability and upgradability.
Otherwise why this "problem" would surface
out in the first place if Intel is so smart and
already has a rock-solid solution?

I guess the reduced pin count will come at
a price; it is not the same as XT-PC of the
past: a 32-bit computer with 8-bit memory bus
running at 16MHz. I think there was a "little"
miscalculation on Intel part to jump directly
into 800MHz while failing to master even PC-133.

Also note that proposed solution to the
infamous "memory-bank problem" (reduce number
of banks to 4) will eliminate any theoretical
performance advantages they hoped to get from
on-chip concurrency.

All this talk about DRDRAM advantage to perform
data backup in background is total BS.

In conclusion, it looks like the Rambus creates
more problems than solutions.

Regards,
