More news on nv30 include 256 bus confirmation

[sancheuz]

Maybe it will have 256 bit bus after all, and all the other goodies: http://www.reactorcritical.com/#l1244

Oh, and the Inquirer( which i'm really starting to not take seriously, but i read anyways) said it could confirm that the nv30 will have 1 ghz ddr2 memory.
http://www.theinquirer.net/?article=5833
Side note, if this is true, 256 bit bus memory, adn 1 ghz ddr2 , then what kind of transfer rate can we expect from this sucker.

I don't see why people are being specific with things like memory speed. There will likely 2 or 3 versions of the card, like a Ti5200 with 600 mhz ram, a Ti5400 with 800 mhz ram and a Ti5600 with 1 ghz ram. Though I think 1ghz is unlikely.

[Joe DeFuria]

I don't believe anything I read on NV30 anymore. Every time there's "confirmation" that it's 256 bit bus, there's "confirmation" from another source that it's 128.

All I know is, if it is 256 bit bus, with 1 Ghz effective DDR-II, that's going to cost an arm and a leg....

Right. Isn't the choice of memory speed up to the board manufacturers anyway?

[SurfMonkey]

Maybe the 256bit bus rumour AND the 128bit rumour are both correct. nVidia maybe releasing a whole lineup, the high end *may* have 256bit memory buses and the mid to low end *may* have 128bit buses. Just like ATi are doing now.

Though getting a 256bit bus to run at 1Ghz without EMI and stuff crapping on your signals will be an achievement.

[Cotita]

why stop at 400mhz core 1ghz memory?

since these are just rumors then lets make one up

lets go for 3ghz dual core and quadband gddr3 512 bit bus 2ghz SGRAM +64mb embedded ram.

I think he has a point. You may be right.

[koneill]

the truth is that no one who counts has ever "confirmed" a 256-bit memory bus; rather, they have confirmed just the opposite in saying that a 256-bit bus is too expensive and unnecessary.

I just can't stand the inq. for being so uber-confident.

Actually, i think you got a point.
I'm really wondering if we aren't going to get a little IDRAM ( Integrated DRAM ) , maybe 2-4MB or something and 128MB normal DRAM.

I'm no expert in this, and this could be a completely ridiculous idea. However, i'm wondering if this couldn't be very efficient in static meshes cases.

What's making me think this? Well, look at that:
http://www.graphicshardware.org/previous/www_1998/presentations/kirk/sld063.htm

It's a presentation from the 9/17/98, by David Kirk. The very same man who said 256 bit bus is still too expensive.

Why am i thinking that problem is maybe resolved? Because 99% of other problems he talks about there are resolved: Aniso, AA, ...

Also, another page of that presentation is very interesting:
http://www.graphicshardware.org/previous/www_1998/presentations/kirk/sld062.htm

That proofs that according to Kirk, the future IS integrated DRAM. Too bad it seems to be on a list of very future-oriented things. Oh well.


So, in conclusion, it's unlikely they used IDRAM. But maybe they'll use a little of it for things like static meshes. However, i fear it is wishful thinking :(

mmm...idram = edram ?

edram is expensive, 256bit is expensive. obviously 256bit bus is not overkill, ATI's selling the chip at $400, so it can't be overly expensive. of course it might be harder to sell NV30 at that price with a 256bit bus. Kirk's statement was really old, and as i remember, it was not clear that he was actually talking about NV30/DX9 hardware. it may have been more of a reference to something akin to Parhelia, where obviously the bandwidth was "wasted."

That was confirmed?
Wow

Give me a break. I'll wait for the official info and until then, THERE IS NO CONFIRMED.

Agreed.
All that was confirmed is that many months ago, 256 bit memory bus was overkill according to David Kirk.
Maybe it isn't overkill anymore.

What?

[INNOVISION]

He is speaking russian I believe.

But anyway, NOTHING is confirm. The only thing we know that it uses 0.13u, and support DX9.

[borntosoul]

that was a maxwell smart joke

[SavagePaladin]

Hehehe
that was a wierd show

Yes. It was "confirmed" in a Maximum PC interview with David Kirk wherein he clearly states that a 256-bit bus is both unnecessary and too expensive.

What I meant to say is that, given statements such as those, I'd say that we're that much closer to the 128-/256-bit answer being that much more "confirmed."
