G70 Specs?

[Cheesetogo]

Is it going to be possible to buy an xbox 360 and take the graphics card out to use in a pc? Or is it going to be using some wierd connection?

 

[Amplifier]

If that were possible I'd chop up XBox's for a living and sell the CPUs for $200 each and the GPU for $600.

There seems to be a few rumours in this thread, so here's some more:

Digitimes

0.11 micron.
3rd quarter
$549
2x6800Ultra
Preview end of May

Nvidia will unveil its next-generation flagship chip, the SLI-supporting G70 graphics chip, at the Computex Taipei 2005 show from May 31 to June 4, according to motherboard makers in Taiwan.

Market sources indicated that the Nvidia G70 should deliver twice the performance of the current flagship series, the GeForce 6800. The chips will be built using a 0.11-micron process at Taiwan Semiconductor Manufacturing Company (TSMC), as opposed to ATI?s R520 chip, which will be manufactured using a 90nm process, the sources suggested.

Since the G70 is currently under non-disclosure agreement (NDA) with Nvidia, motherboard makers declined to provide more details about the product. Nvidia also had no comment on the news as it is its policy not to comment on products not yet released.

The makers did say the G70 may begin volume shipments in the latter half of the third quarter at the earliest and will retail for US$549.

Um, please....I mean, really, if you're going to ask ridiculous questions...

Yeah, the current rumor is 24 pipes, 110nm, and at least 450MHz. Not bad, if it debuts at the same price points as the current 6800GT and U (with am ultra-luxury 512MB option for those so inclined).

They say $550, as I posted from Digitimes.

my money is on a 24-pipe design, and very modest clockspeed increases, 450MHz-500MHz sounds plausible. It's possible they will physically be 32-pipe designs, but even if so, it's sounding like they will only use 24 of them in the first generation of parts. For memory, I think they have GDDR3 up to 1400MHz right now, so that's a safe bet for at least some of the parts. Maybe they'll try some 1.8-2.0GHz GDDR4 for the Ultra flavor and 1.4GHz GDDR3 for the GT, and i imagine both will come with 512MB buffers, maybe a 256MB version for the GT or non-ultra if they have one again. And hopefully they'll be WGF 1.0 compliant so they'll run Aero Glass with all its cool features.

I'm just curious about the mainstream market. With prices on 6800GTs and X800XLs dipping below $250, they're gonna need a card that can keep up with these cards for the $200 segment. I'm guessing we'll see a 12-pipe 7600GT @~600MHz or a 16-pipe card @~300-350MHz, and either really fast GDDR4 and a 128-bit interface or a 256-bit interface with slower GDDR3. And i'm sure they'll all be at least 256MB cards.

 

[Munky]

I think for the midrange card they will have to make something that's faster than the x800xl, because otherwise I don't see why anyone would buy it. And I'm sure the x800xl will be selling for about $200 by then. This is only speculation, but I'm thinking 16 pipes @ 400mhz, or 12 pipes @500+ mhz, 256-bit in any case if they're not stoopid . By midrange I mean something like the 6600gt is now, not some turbocache crap or the underclocked 6600 vanilla.

As far as the high end G70 goes, I'll speculate it will be a 32 pipe design, but only 24-pipe versions will be available initially. That way they don't have as much heat dissipation to deal with, and tweak the card further for the mid-year refresh, like a G70 Ultra or something. Unless of course the R520 is released with all 32 pipes functional, in which case they'd better hope to have a 32 pipe card to compete with it.

I feel the need to correct this. The Xbox GPU is a straight GF3 GPU, with a higher clock frequency than the PC flapship GF3 Ti500. While, technically, a faster GPU because of its higher clock speed, the Xbox GF3 was crippled because of its pairing with DDR400 memory; memory that was slower than the memory on the Ti500 models. Feature set wise, they were identical GPU, they just had different clock speeds.

i thought it had an extra vertex shader on it?

going for 24 pipes with a possible further 8 in reserve makes sense

to be fair we dont exactly need anymore than what we got now, but were gettin it anyway, and extra 8 pipes over current should provide a very nice boost....and when the time comes to have more speed, just unlock the other 8 pipes. this gives nvidias engineers more time to work on things and get things right.

 

[Pete]

The 6800U packs about 225M transistors. You're probably looking at 400M+ for 32 pipes. I think we're going to see a native 24-pipe GPU, with partially defective ones sold as 16-pipe cards clocked slightly higher than the current 6800GT or U. 400M transistors just sounds too huge, especially for 110nm.

Edit: a 550MHz core would put a 24-pipe G70 at twice the performance of a 16-pipe, 400MHz 6800U--provided bandwidth wasn't a limitation.

 

[Killrose]

I've read 2x6800 performance for the G70, but are they talking 6800 vanilla, GT or Ultra? no where did I see which 6800 was specified.

 

[Pete]

It really depends on the G70's RAM and clock speeds. Like I said, memory aside, a 550MHz, 24-pipe G70 would be twice as fast as a 400MHz, 16-pipe 6800U--on paper.

Paper and silicon are two different things, though. Without correspondingly fast RAM (meaning, 1GHz GDR3, which ain't gonna happen), I imagine we won't see double the performance in older, simpler games, but we should see it in newer, shader-heavy ones.

Edit: And when IHVs mention a ____ing of previous gen performance, they typically mean the flagship card (and typically mention a doubling of performance).

 

[ddogg]

i still highly doubt it might be 2X+ the performance of the current cards....although i could be wrong...as u said theres a big difference between paper and silicon..i want to see how much performance the G70s in SLI would produce.

this still going around?

the "correction" was WRONG . . . the Xbox GPU is a GF3/4 hybred . . . more "advanced" than the GF3.

this is really goin to be good for all of us....just imagine spending $250 on a card that can run current games like Doom n HL2 at max settings and future games at high settings....

you do make sense mate

DRAM is the stuff that CPU manufacturers use for L2 cache. It is fast as balls.

No, it'll likely be soldered directly to the PCB.

And there's always the obvious reason, that MS isn't going to subsidise cheap GPUs for ppl who aren't going to buy Xbox 360 games--which is where console makers make their money.

 

[Bar81]

Besides the fact that the ATI chip in the Xbox isn't the same one in the Revolution isn't the same one as Fudo. Makes it kind of impossible to use them interchangeably.

I'd Imagine they are talking 6800 standard. After all 6800 standard has 12 pixel pipelines and G70 is rumored to have 24. (edit: Pete was specualting about whether G70 was double 6800 standard performance or 6800 GT/Ultra performance before his entire post changed).

 

[thanasi]

If its 550 or 500 ill def buy it 32 pipes wow ill get over 200 fps in ccs

Is the chip in revoulution going to be mre powerful or less than the one in xbox360?

It depends on other improvements they can make (eg: z-culling etc) as well.
And usually double performance means double in one specific benchmark for one game using certain settings, and not double on average.

 

[ddogg]

well i hope its double on average...although that might be asking for 2 much
