AMD to PCI-E and DDR2

[marclar1104]

Do anyone know when AMD plans to move into the area of PCI Express and DDR2. I'm really on the fence of whether to buy a P4 or an AMD 64. As much asI really want to go with an AMD 64, its hard to ignore the future of PCI express (a buzzword thats overused i know i know) and if it will be incorporated in the near future, I would be more than happy to wait. Thanks for any help.

PCI Express boards will be out soon for AMD. The new NForce 4 boards will have PCI express, they are due to come out in the next few weeks. As far as DDR2, don't hold your breath for AMD DDR2 boards. The memory controller is integrated into the processor itself so unless they overhaul the processor design, DDR is here to stay with amd.

oh, its a nice day. TO EAT CHILDREN!!!

Thanks a lot!! Good to know, I will definately wait then maybe even give it time for price drop. Also from what Ive heard, DDR2 is not necessarily something that will be utilized for quite sometime and DDR is fast enough to last awhile.

it is useful for Intel as the Netburst architecture which the P4's use is very bandwidth hungry, whereas AMD chips are more sensitive to latency of the RAM.

DDR2 provides more bandwidth but at higher latencies.

It is widely accepted that as DDR2 reaches 800Mhz that the speed benefits will outweight the latency drawbacks - that is when AMD can make a successful move to DDR2.

Exactly, you said it very well. DDR2-400 is useless, DDR2-533 is still dubious. DDR2-667 might become the turning point, and might show more of DDR2's strengths, and DDR2-800 will probably put DDR1 to rest at last... That's if DDR3 doesn't interfere... I read it is more promising than DDR2...

I think and hope that AMD Skips DDR2, and go straight to DDR3, cooler running and higher speeds, remember the failure of FX5800?

 

[marclar1104]

Yes that would be nice, but that would take quite some time to come around, Ill wait for PCI-e but DDR3 is a bit iffy.

 

[Mephistopheles]

Well... theoretically, DDR2 shouldn't put out too much heat...

And also, I think DDR2-800 really is everything we'll need for a while. It offers 12.8GB/s in dual channel configurations, and that's more than enough for 2005 and 2006!... I'm thinking DDR2-800 will finally, when developed well, kill DDR1 off.

The memory market has been improving DDR2 steadily... There's even DDR2-533 with 3-2-2 timings, which I find quite acceptable. Once DDR2-667 gets widespread, DDR2 will look much better... I'd expect DDR2-667 to catch on by 1H05.

What's the difference between DDR2 and DDR3?

That... that I do not know. I'd like to know that too.

If it's more bandwidth, then that's pretty much pointless. We already have more bandwidth than sense here. Maybe it's DDR2 without the latency implications?... I have no idea.

Voltages, heat output, densities, and clock signaling. I personally don’t see DDR3 making an appearance for a few more years. Last I checked they needed a mature 0.65u process to make the modules.

Micron NEC and Samsung say they can do it on 0.09u be interesting to see if that’s possible.

I saw a blurb about AMD going to Hypertransport 2 at some point, with bandwidth of 20.4 gigs or something. Anyone know more about this?

 

[AMD101]

DDR3 is just DDR2 with the latencies of DDR1. Dont worry about not having DDR2 in you next system as right now its not fast enough to offset its latencies. When it becomes fast and mainstream and also cost-effective, AMD will start using it.

DDR-3 is having the same interface that DDR-2 2 bit on 2 fetch 1 cell / 4 bus.Due to run start at 200 mghz cell and move up to 400 mghz cell.

i need to change useur name.
