Will DDR2 replace DDR anytime soon? its seems so much faster so why isnt is giving DDR2 users advantageS?
When will DDR2 replace DDR?

Systems are being built with DDR2 now, my Dell Dimension 8400 shipped with 1 Gb of DDR2 as does all Dimension 8400 computers. However, at present there is no speed advantage over convensional DDR memory but rather DDR2 was introduced to get "room to grow" from what I"ve read. Perhaps a poor analogy is that the Pentium 4 when introduced had little speed advantage over the Pentium III at the same speed (mhz) but because of architecture, the PIII had reached it's speed limits, but the P4 had headroom. At some point a technology reaches it's limits and a new design has to be introduced to continue the growth trend... DDR/DDR2 is that point. It isn't really an advantage but eventually probably all systems will use it and as the memory bus ramps up, then the advantages will become more apparent.
BTW cybernight, DDR2 isn't that much more expensive. Nothing like RAMBUS RIMMS were! I've looked at prices and right now it is between 50% and 100% more expensive and the price is dropping. Probably in a year it will be close to the same as DDR. I purchased my Dell with 1 Gb so that I'd be in good shape for a while, and eventually when I do want more memory, it shouldn't be any more expensive.
DDR2 is pretty much mainstay in all vid cards now.....I would say in about 2 years most all the mobo chipset will be running with it. You need to have AMD implement changes in memroy controller to have any use for it now..Maybe it will come with dual core chips???
Actually, I'd call SDRAM pretty obsolete at this point. There hasn't been a new chipset/motherboard (excepting a handful of notebooks) using it in, what, 3+ years? Unless you're trying to upgrade an old P3 system or something like that, it's all but useless.
DDR2 will become dominant when it becomes either a) significantly faster than DDR (this will happen probably within a year, as they push up towards 300-400Mhz DDR2), or b) hits a better price/performance ratio than DDR (1-2 years?). Athlon64s with DDR2 support will also be required to really make some progress, but no date has been set yet for their release (possibly Q2 or Q3 2005, but we're talking at least a new stepping and possibly a new socket).
However, that said, DDR SDRAM is not going anywhere for at least a couple of years. Especially given the speed increases that have been managed lately (such as 'PC4000' memory, etc.).
If SDRAM was "obselete", it wouldn't cost as much as it does.
New computers don't use it I know, but it IS still in USE by tons of home PCs.

I stand corrected!!! But clearly vid cards were becomng bandwidth limited and thus the move. Currently the P4 with dual channel are fine at 800fsb but it is clear that a 1066fsb would have tough time we PC4200. When this become more mainstream then maybe the p4s will be bandwidth limited and need the DDR2....Dual coire I think is the first real big push for this, IMO...

I'm a little puzzled about p4, because intel has stated that they will not make 4Ghz p4, which makes me think that there must be some major redesign on it's way, maybe some variant of pentium-M. At the same time it has been shown that the new p4EE 3.46Ghz with 533Mhz FSB doesn't really improve that much over the p4EE 3.4Ghz with 400Mhz FSB.
For dualcore processors it might be a totally different story, it's pretty hard to tell since we know nothing of how they perform. It seems logically that they will hunger for more bandwith, and for that DDR-2 will most likely be the future. There was a story/rumor at the Inq about next generation opterons to haveing 1207 pins, this could be either DDR2 support or maybe a move to a 256-bit memory controller, which is another way to increase bandwith. But when they decide to go DDR2 I can't really say, but as long as they can beat intel systems on DDR1 I think they'll keep doing that.

It's expensive because it's a low volume, obsolete, legacy product (looks sadly at three PCs in plan sight, all using SD
)SDRAM costs a lot because it's obsolete, not the other way around. They hardly make it anymore (there's not much market for it, and all the manufacturers are focused on DDR2 and GDDR3), so they charge a premium for what little is produced/available.
It's simple economics -- low supply = high prices unless demand is also extremely low, and there's enough upgrade demand for older systems to keep what stock remains priced fairly high.
i personally dont think we will see ddr2 around long. when they came out with ddr no one thought it would scale to even pc3200. just take a look at videocards, ddr2 was used for very few generations before being replaced by ddr3. not only that but with the a64s there is not a need for extra memory bandwith at this time. i guess we will just have to wait and see
and the pentium m is a successor to the pentium 3 so in a way the pentium 3 will most likely outlive the p4 by a bunch. pentium m gogo~~
ddr2 is a marketing gimic and please dont say woot newb. intel is not bad right now its just amd is better for gaming but intels can be better for alot of other things.
