Only consumer of DDR2 until 2004 ?

[noko]

That makes sense except you would expect ATI would sell a massive amount more of OEM boards then Retail boards. So I am still wondering? Unless 3.6ns memory is what available and being produced while 4ns memory is not being produced or speed binned.

So what? Big deal.....

You know.. The only point of using DDR-II (especially for Nvidia) is to increase their bandwidth.

AS it is even with their 500mhz DDR-II they only have 16GB raw. 3.8GB lower than the 9700 with 200mhz slower ram. Which proves that you do not need DDR-II in order to sport the best bandwidth. I can easily see a situation where the R350 only uses DDR. AS I dont think Ati has to go to DDR-II. They have better technology under the hood.

After all if the R350 was paired with 400mhz DDR based on a 256bit bus.. they achieve.. 25.6GB bandwidth, and with improved HSR/compression etc.. Could net a nice jump in FSAA performance. (even without improved HSR over the 9700)

For those of us who are severely ignorant, what exactly is GDDR3? I know it's a next generation memory that ATI has been pushing forward, I think, but is it comparable to DDR-II? Or perhaps it's a version of DDR-II, I don't know.... thanks for any info!


edit: nevermind, I looked it up myself. wow... GDDR3 is ment to be twice as fast as DDR-II. I can't wait to for ATI cards to have this stuff.
DDR-II who?

The way I see it, the problem was most likely related to clock speed. It just seems obvious to me that a current R300 board with little/no changes except for the DDR2 memory (anybody know if DDR2 is pin-compatible with DDR?) wouldn't be able to run at much higher clock speeds, if any higher.

Don't forget that DDR-II uses SSTL_18 signalling. A straight switch to DDR-II on the current 256-bit would probably result in much higher clockspeeds from the word go.

MuFu.

P.S. GDDR3 is based on DDR-II, yes. I think details of the spec are hazy at best right now but not doubt it'll scale a lot higher, being specifically designed for use on videocards.

DDR-II is not pin-compatible with DDR - all the packages I've seen have had more pins.

 

[megadrive0088]

Aye. I'm dreaming of a new rig with DDR-II as system memory. A 3.5 Ghz P4 with HT, and R350 with 256 MB of even faster GDDR3.

This whole thing strikes me as highly ironic, seeing as Nvidia has recently shown that they can't predict the future even for themselves. Yet now somehow they are able to know that no other consumer graphics boards will be available from other vendors until 2004?

I guess they splurged and hired the Fabulous Bobo over the past month or so. Either that or maybe they fired him, since the wild-assed inaccuracy they've become known for is quite usual for "fortune tellers".

Funny, someone reminded me on another forum that the guy from ATI who demonstrated the 9700 w/DDR2 on Tech TV was one of the top guys on the JEDEC committee. I'd hope that he would at least know what it was he was demonstrating!

'Sources'....sheeesh!

Um, my understanding is that it was DDRII (noones debating that), but that it was running in a backwards compatability mode with the DDRI complient controller.

That's exactly what the article said. What I'm saying is that I'm not sure that a JEDEC higher-up (ATI employee or not) would go on TV and intentionally misrepresent something like that.

I'm fairly sure that I remember a statement from ATI saying that the R300 supported both DDRI and DDRII memory technology.

Well, THAT certainly puts an end to that! (where's that spelling checker??!!)

 

[Dave Baumann]

His reply to me was:

Yes, we have DDR2 boards running full DDR2 protocols.

 

[Mummy]

I believe ATi has DDR2 running with full protocol, but you guys shouldnt take words coming out from ATi employees (or any other company) like if it was divine speech (its clear why is that right?).

Hmmm... so does that also apply to all other companies? Or are we singling out ATI as liars......

Depends 8) They won't go saying, yeah we used a trick and let the president of JEDEC show it as the first trully DDRII card

 

[martrox]

Well, I guess the whole thing here revolves around IF the R300 is going to make it to the retail market using DDrII. IF the NV30 has a real advantage over the 9700, AND IF using DDR II will give the advantage back to ATI, wouldn't it be to ATIs advantage to produce it?

 

[Evildeus]

For that we will need to wait unfortunately

while i run circles around you with my dual sledge hamer system running at 3ghz with a r350 with 256mbs of gddr3
