NVIDIA'S flagship G71 won't be able to get to the speeds the firm wanted it to. We reported before that Nvidia needs at least 700MHz to beat ATI's R580 based X1900 XTX. However, according to our sources, the G71 will be nothing more than a 90 nanometre G70 die shrink. It won't have more than 24 pipelines but you never know what Nvidia has exactly up its sleeves.
It will use GDDR 3 memory running at 800MHz, with a 1600 MHz memory clock. In the case it ends up with 24 pipes it won't be enough to touch the R580, Radeon X1900 XTX performance crown. If Nvidia did put 32 pipes in G71 chip this would make its chip as a much better competitor and will make ATI run hard for its crown. We think that Nvidia could win most of the benchmarks with 32 pipes.

If true then it looks like the X1900XTX and the 7900GTX will end up about even with the 1900 being faster in shader heavy games and the 7900 faster in OGL.

Hmmm, looks like the 7900 GTX may not obliterate the X1900 like everyone first thought.
I predict it will still beat it in most benchmarks though.
What I cant wait to see is how much this card ends up costing. If it by some miracle is cheaper then the XTX (unlucky 7800 GTX 512mb owners) then I'll sell the XTX and get one of these. All I know is, Quake Wars is THE game for this year, and thats OpenGL.

Well its the INQ, so im not making any judgements. Im getting more curious day by day what G71 really is. Is it a die shrink? does NV have something up its sleeves? what new features? 24 pipes or 32?

March is coming soon, i cant wait. :)

the article also claims it will sell for $499

Some web pages have contacted nvidia for a preview of the 7900 cards and this is what they could note down after watching the card:
Both the GTX and GT version will be released on 9th of March 2006, being inmediately available on stores.

The 7900 GTX:
Will be released with 256Mb and 512Mb of Ram.
CORE: 90nm, range from 650 Mhz to 750Mhz, not confirmed yet, only nVIDIA knows.
Pipelines: 32 Pixel Pipelines
RAM: Samsung GDDR3 1.1ns chips clocked at a range of 800-900 Mhz, so 1600 to 1800 Mhz effective.
The 7900 GT:
Will be released with 256Mb of Ram.
The PCB layout is different from the 7800GT and the PWM area is slightly different too.
CORE: 90nm, clocked at about 450Mhz.
Pipelines: 24 Pixel Pipelines
RAM: Samsung GDDR3 1.4ns chips, 700Mhz possible, so 1200 to 1400 Mhz effective.

From this specs I think the new 7900 GT will be very similar, if not identical, to a slightly overclocked 256Mb 7800GTX.

Yeah, I can't wait for March either. Speculations all over the place. I hope nVidia will be able to positively surprise us and release a real monster ;) I doubt it though. Even at the upper end of the rumored specs, it probably won't be enough to beat ATi where it really matters, i.e. in shader-loaded games where cards struggle to deliver a playable frame rate in high settings. If the Inq article is correct, it's gonna be even worse for nVidia - it won't reccover much in games like F.E.A.R. and won't be able to beat the XTX by a lot in other games, even in Open GL.

Anyway, the MSRP (if it proves correct) is attractive - 500 bucks for the GTX compared to 650 for the XTX looks nice. SLI action anyone? ;)

You can actually get a 1900xtx for $540 - http://www.monarchcomputer.com/Merchant..._Code=190262&Category_Code=VC-HIS-PCIE

What websites? If Nvidia gave them a preview, they would be under a NDA and couldn't disclose that information. Just like Anandtech

I just knew that 700+ mhz on core was wishfull thinking.
Something also tells me They might try to pull an Ultra again.

I suppose we just have to wait until march. The suspense is killing me. If this is true then perhaps ATI will be king for now, until DX10 at least.

Then that's the most believable rumor so far because it would be just like (I think it was) the X1800XT vs 7800GTX where the shader intensive games (esp w/ AA/AF) ATi won and the OGL games NVidia won.

If I can get a 7900GT for ~$400 in two weeks, that'd be a good deal, assuming it's clocked to give 7800GTX numbers (or better) stock and the core is revised to have stronger shading performance and performance with AA/AF on.

Of course the things that matter most to me would be a fix to get rid of the IQ issues (shimmering and whatnot) that 6800/7800 series cards seem to have in some games, and most of all a quieter stock cooling assembly.

I doubt that the x1900XTX would beat a 24 pipe 650MHZ card from Nvidia.

And some people kept expecting 700+ mhz AND 32 pipelines. :D Its the same case as with the R520, people expected it to be a 32 pipe "monster" which would destroy the competition.

Why not get a 7800GTX now rather than waiting for the 7900GT (same price, same performance like you implied).

If 7900GTX is 24 pipes at 650mhz then 7900GT should be pipe reduced again but at higher clocks putting it at a similar performance level as the 7800GTX.

Nvidia plans to price its Geforce 7900 GTX very aggressively. That?s what you do if you cannot beat your competitor on the performance side. This card should cost $499 only and even the price indicates that the card won't be able to get the performance crown back.
Doesnt sound good .. :confused:

But if all nv have done is a die shrink without upping the pipes then what you've basically got is a 7800GTX 512MB with a 100mhz speed bump. No slouch but probably not a definitive X1900 beater.
Like I said, I reckon NV will hold the OGL crown and ATI will rule the shader heavy games.

Speculation is fun. ;)

Well. I guess it depends on how you look at it... If the 7900GTX is $499 MSRP, and it performs roughly like a 7800GTX 512, that would mean by probably sometime in April you will be able to build the hottest SLI rig around for about $800-900. Considering the cost of a single 7800GTX 512 is still $750, that doesn't sound too bad.

What ATI really, really needs now is a decent Crossfire chipset/motherboard. I've been checking out the current offerings and trying to find info on RD580, and I'm still reluctant to seriously consider CrossFire at this point. Even Asus' new A8R32-MVP Deluxe still uses the ULi southbridge, which doesn't give me much confidence in ATI's chipset.

We need some AEG members to give their "opinion" on what they think G71 is going to be. I'd be interested to hear it.
