I here the death knoll of rdram. Read inside

[Adul]

Well maybe just a slow degrade anycase, it doesn't sound good.

Form anand's article

The first point of discussion was the future of RDRAM with the Pentium 4 platform to which Mr. Siu quickly reaffirmed what we had been hearing from motherboard manufacturers - after the 850E, there will be no more RDRAM based chipsets for the Pentium 4. Although Mr. Siu (as well as most people in the industry) believes that RDRAM is technically superior to DDR, he made it clear that Intel's roadmap was hurt severely by an overly strong commitment to the technology which today still isn't as economically viable as DDR.

The transition in the future will be to dual-channel DDR which can be seen in Intel's forthcoming Granite Bay chipset (see our previous page on Gigabyte). It's too early for Intel to commit to DDR-II but it seems as if that would be the logical step after DDR333 for Intel assuming that they continue to phase out RDRAM on their platforms.

This has pretty much been known for a while sadly. However, I will just wait and see. To be honest, it all is falling on what will be the cost of Granite Bay. The truth is that GraniteBay could be faster than 533fsb+PC1066, but then, the issue is cost of it. I doubt hightly that the performance advantage for Granite Bay (if any) will be significant, so it falls on the price, which as I have stated countless times, am still very concerned about vs 850e. We'll have to wait and see, and as I said in your last thread Adul, I really have high hopes for SiS 658. It will likely be priced cheaper than 850e, and if SiS could suprise us once again like they did with 735, it could be the best chipset for the P4.

 

[Adul]

we shall see.

Bill Siu is a pretty cool guy, by the way. I've heard him speak a couple of times. He knows his stuff and he doesn't mince words.

Via is supposed to have a dual-channel Pentium 4 chipset some time this summer according to a roadmap that I saw back around Christmas. I wonder if that is still in the cards or if there will be licensing issues around that as well. I haven't heard anything about it considering it should be getting close to release.

The "death knoll" of RDRAM sounded right about the time that group of lawyers masquerading as IP specialists stole others' IP and attempted to extort royalties from every Tom, Dick, and Harry. Why are you surprised?

DDR-II is definitely the future. Intel's amazing success with i845-D will undoubtedly spur them to bring Granite Bay forthright and give RDRAM its last kick in the ass. And I say don't let the door hit you on the way out

 

[MadRat]

If DDR-II doesn't have lower latency than PC1200 then I don't see why RDRAM will go away any time soon. Latency is going to be the death toll (think hell's bells) of DDR technology when it gets to the meat of the issue. RDRAM latency drops faster as speeds increase as compared to DDR technology

When it gets down to it we just need larger low-latency caches and can live with either technology. L3 caches featuring 1T-SRAM are the future.

Well I just ordered a

CPU : P4 2.0A ghz (Northwood) 211
Mobo: Abit TH7II-raid 130
Mem : RDRAM 512MB 200


system..

should have I not ordered it since RDRAM IS DEAD????

should have i ordered a DDR board/ram instead?

shoot. ;( i'm feeling sad now.

 

[grant2]

subxeon that's right, at midnight December 31 2002 they are going to flip the switch and turn off your RDRAM.

well, I just ordered:

Mobo: Abit IT7-MAX
MEM: 2x512 DDR

There is nothing wrong with RDRAM, it's damn fast and gets the job done better than DDR with a P4 at the moment. I wish it's future was not so grim, I like RDRAM more than I could ever like DDR, if it werent for the greedy people behind rambus, it might have been different.

 

[Windogg]

Death to Rambust Inc.

May the technology become an open standard for all.

That may be true, but its moot in dual channel which will cut the latency by one half. So if you have 8ns DDR, in dual channel you now have a 4ns latecency not to mention awesome bandwith for that latency.

People will have to get used to buying DDR in pairs and probably from same manufacturer to avoid problems. I'm sticking to rdram, but the dual channel DDR from intel will most likely smoke anything that's already out there. By then which they said around first quarter 2003, we'll have 3gig P4's. It's going to be awesome

 

[Galvin]

I mean i'm sticking with rdram till this comes out.
Dual channel = awesome.

RGN, that sounds like a pretty sweet system, how much did it cost? I am in the market for a new board + CPU (I am still using my trusty celeron 500), and I am considering a similar setup (except with 512 MB ram, not a gig).

 

[MadRat]

<<So if you have 8ns DDR, in dual channel you now have a 4ns latecency not to mention awesome bandwith for that latency.>>

*cough* bullsh!t.... *cough*

You made that up. Its far from the truth. The latency has to do with the way SDRAM memory works, not how many channels it has to the memory banks.

 

[pm]

Galvin, as Madrat so tactfully pointed out, you are mistaken. Dual-channel doubles the amount of data that can be sent in parallel by doubling the number of data wires.

you don't happen to have an article to back that latency claim up, do you?

 

[Bozo Galora]

i wouldn't count rdram down and out so soon

they are talking RIMM 9600 64 bit at PC1200 9.6MB/sec

[neuralfx]

actaully the post said intel did not plan to make further RDRAM chipsets for the P4 .. ah hasn't everyone else caught on .. HAH its so obvious, VIA is going to start developing RDRAM chipsets for their NextGen Cyrix line of processors. This coupled with their new UltraLight bus technology, FAST-Cache access method, and MegaBypass technology VIA will rule the processor world .. muhahaha no one has figured it out yet !

heh .. I'm tired .. actaully what will probably happen is Rambus will read this post and figure out that VIA is stealing their "MegaBypass" technology and sue VIA into the ground .. =)

[MadRat]

ELFenix-

I was kidding around.

neuralfx-

Its SiS thats making the RDRAM chipset, actually, not VIA. If SiS is developing future RDRAM chipsets then Intel has no need to do so, correct?

If the new article at Hardocp.com is right then where is the "death knoll(knell, I think you mean, unless you are thinking of that other conspiracy, the grassy knoll )" ?

Our friends at Anandtech reported yesterday that Mr. Siu had stated that the
current i850E would be the last chipset supporting RDRAM, although upon writing this it seems that the statement has been removed from their website. Mr. Siu explained to us that he had been misquoted. While he would not go into detail, he gave the impression that Intel would continue to support RDRAM in the future. So it seems as though we'll certainly see RDRAM and DDR RAM both stay strong in Intel's current marketing strategies.

While it has been rumored that we would see Intel's Granite Bay chipset supporting dual channel DDR RAM come to the desktop market sometime this year, Mr. Siu set us straight on the matter. While it's probable that Granite Bay will show itself this year, it will not be in a desktop configuration, but most likely in the workstation environment. When questioned further, Mr. Siu did state that we would see Granite Bay on the desktop in 2003 supporting 333MHz DDR for their current Pentium 4 Northwood CPUs. This chipset will be codenamed Springdale, as verified through other sources, and will be capable of dual and single channel DDR support. The Springdale will be coupled with the ICH5 hub that will support wireless LAN and Soft RAID when utilized with Intel's Application Accelerator.

 

[Galvin]

So duak channel DDR doesn't work the same as dual channel rdram where latency gets cut in half then?

So how much latency do you get with dual channel DDR if you had two sticks of 8n DDR ?

 

[ST4RCUTTER]

Uh...I think you have that backwards. Because of the serial nature of RDRAM, the bank farthest from the CPU has the greatest latency. That means that all the banks before it must be "slowed down" by adding wait states so that they all run syncronous. DDR does not have this penalty due to its parallel architecture. So at a given speed, DDR will have less latency than RDRAM. Increasing speed does reduce latency, but RDRAM certainly doesn't "drop faster" than DDR as the Mhz are increased.

yeah, and ken caminiti was misquoted when he said that about half of baseball players were taking steriods, when he actually meant 2 or 3.
