I doubt this is real, but since its 2Gb it'd most likely be a GX2 or some kind of dual-chip. There's no other reason they would make a 2Gb card. If it was real I mean. ;)

[nekrosoft13]

2GB GDDR5 512-bit

like capt said, probably two chips with 1gb gddr5 256-bit

Very interesting...

I dont think it will be a dual chip but single chip, GTX 350 was sampled since last month.

GTX 350 spec:

GT300 core
55nm technology
576mm
512bit
DDR5 2GB memory, doubled GTX280
480SP doubled GTX280
Grating operation units are 64 the same with GTX280
216G bandwidth
Default 830/2075/3360MHZ
Pixel filling 36.3G pixels/s
Texture filling 84.4Gpixels/s
Cannot support D10.1 .10.0/SM4.0

http://en.hardspell.com/doc/showcont.asp?news_id=3764

Look like GTX 350 is a 55nm shrink of GTX 280 with enhancements and packed more shaders increased to 480SPs and GDDR5 memory to handle massive 216GB memory bandwidth on 512bit bus. Can you imagine overclocked GTX 350 versions with 256GB and 307GB memory bandwidth? :D

[Xion X2]

Cannot support D10.1 .10.0/SM4.0


Please tell me that this is a false rumor, and that Nvidia's next part will support DX10.1.

If not, then I'll be pissed if they somehow coax developers into staying away from it because they still don't support it. 10.1 brings performance enhancements that could benefit all users.

As much as I'd like to see a card like that this year, the chances of that being real are slim to none. I never remember hearing about hardspell before a few months ago when they started flooding the internet with hardware rumors that mysteriously, no other site reported. I wouldn't even pay attention to those specs unless a more reputable site actually mentions a GTX 350.

I still think its going to be a GX2 if it is real. There is absolutely no need for a 2Gb card at this point, unless they're willing to waste a lot of resources just to compete with the "2Gb Memory" label on the 4870 x2 box.

EDIT: Although the memory size does seem to scale with the number of ROPs on the GTX cards, so I guess its possible they just stuck two chips together to get those specs without using SLI. That'd be ideal, but again, I highly doubt it.

That is a large core 576 mm - squered. almost 2.5cm each side!!!

800 MHz maybe a little aggressive given the die specs even if at 55nm

Well if you think it is a dual chip then it would have called it GTX 350 GX2.

[CaptNKILL]

Maybe, maybe not. :p

For one, nvidia can call a card whatever they want. Second, the rumor mill can say whatever they want. Someone may have gotten some leaked specs or even just a hint at a GTX 3xx card and this info could have been speculation which was then posted as fact on hardspell. We don't know. I just find it very hard to believe that we'll see a card with these specs.

If we do though, I want one. :p

[MUYA]

2 GB ..GDDR5 and at 512 bit? I don't think so. 256 Bit yes..and it would be enough but 512 bit?

[-=DVS=-]

When it's to good to be true - it's not true. :(

Lately we see many rumors about soon coming NVIDIA cards but this is the first time I see rumors for sale, even eBay has more strict rules.

The site has listed for sale GTX 350 (Q4 2008) GT300-GPU 55nm PCI-E2.0 2GB GDDR5 512-bit,
and GTX 280+ (September 2008) GT200b-GPU 55nm PCI-E2.0x16 1GB GDDR3 512-bit
There is only 9 days left in September, I think if GTX 280+ was ready for sale so soon we would see many more rumors about it maybe even some benchmarks and prices.

There are many rumors that GT 206 core, the GTX 260 55nm shrink is first upgrade on the NVIDIA road map. I wonder how come the site doesn't have it for sale yet.:)

Please tell me that this is a false rumor, and that Nvidia's next part will support DX10.1.

If not, then I'll be pissed if they somehow coax developers into staying away from it because they still don't support it. 10.1 brings performance enhancements that could benefit all users.
I think NVIdia will skip DX10.1 completely for simple reason ATI is ahead with the support and it looks good at ATI cards and software.

For the same reason NVIDIA hopes the TWIMTBP advertising supported games wont use it.

I doubt NVIDIA can use dual GTX 280, even with 55nm shrink the chip is going to be still large with 512bit bus, but than why use the 2GB GDDR5 memory.

Also how many GTX 280 55nm shrinks we are going to get, the above AustinComputers has already two for sale.

"Cannot support D10.1 .10.0/SM4.0" so if can't suport DX10.0 what the hell it will support?

Many sites also posted the supposedly NVIDIA road map and there is nothing there about GT300 core.
http://www.hexus.net/content/item.php?item=15388
By the way Hardspell (http://en.hardspell.com/doc/showcont.asp?news_id=4022) also posted the same.

So I'm more confused than ever but I think my best choice before Nehalem comes out is going to be the HD 4870 x2.

[MUYA]

And look at supposed shader clock....2 GHZ! yeah right!

[K007]

if only this is true.

[walterman]

I also think that it could be a GX2 card with 2x GT200b @55nm.

But, after some photoshop with the die area of the GT200, i think that it could be possible to pack 480SPs, 100 Texture processors (84.4/830 = 100 +-), keep the 32 ROPs, redesign the memory controllers to support GDDR5, and expand the thread scheduler & raster setup.

It could raise the transistor count from 1.4B to +1.65B. About the clocks, i think that 830/2075 are too high for this shrink & transistor count. 700/1500 could be more real.

But, how do you mix this rumor with the leaked ELSA roadmap showing the GT212 chip ? :confused:

[slaWter]

Wow those specs are insane! Most likely not true :(

[AngelGraves13]

With this...they'll surely win back the performance crown.

[Monolyth]

I don't think nVidia will win back the performance crown this year.

Vaporware.

55nm is a 18% die shrink. Twice the shaders in 18% more space? Nah.

[walterman]

55nm is a 18% die shrink. Twice the shaders in 18% more space? Nah.

I thought that too, but, check this pic of the GT200 die:
http://realworldtech.com/page.cfm?ArticleID=RWT090808195242&p=11

Make it a 18% smaller in photoshop, keeping the same canvas size, cause the 55nm chip is supposed to have the same die area. Then, duplicate the green areas (shader processors). They fit in the free space. Then, expand the pink areas (texture processors), by a 25% (84.4Gpixels / 830 MHz = 100 Texture processors +-. You have 80 Texture processors in the 65nm GT200. So 100/80 = 25%). After this, there is still free space. You can keep your 32 ROPs, and you still have free space to modify the memory controllers (GDDR5 support), and to expand the thread scheduler & raster setup, and prolly to add more redundant logic.

Now i think that it could be possible, but, the transistor count will grow a 18% too (same area, higher density). Prolly, problems with the yields & frequencies for the core/shader. The same story again.

[jlippo]

I just hope they will finally announce new generation chip and name it properly. (nv60.. ;))
It should come within a year if my calculations are correct, it has always been around or under 3 years to announce a new generational leap.
(nv10-nv20-nv30-nv40-g80-gt300?)

Sigh,I miss old good nvxx naming scheme, it was so easy to see which series the chip actually belongs to.

[cairastravis]

55nm is a 18% die shrink. Twice the shaders in 18% more space? Nah.

I'm not saying that I think this thing is likely, but it's not 18% more transistors in the same die area, it's just under 40% more transistors. You have to square the difference. (65 / 55)^2 = 1.397.

[Monolyth]

You had me at nanometer.

[AthlonXP1800]

55nm is a 18% die shrink. Twice the shaders in 18% more space? Nah.

If you look at Radeon HD 2900 from 80nm to Radeon HD 4870's 55nm, that is 45% shrink from 80nm to 55nm process but not the die size! HD 2900 packed 320 shaders on 700m transistors at 80nm 408mm² die size and HD 4870 packed 800 shaders on 956m transistors at 55nm 260mm² die size that is 56% smaller than HD 2900 die size. If AMD want to make HD 4870 on 55nm at the size of HD 2900 die, they can pack 400 more shaders to make 1200 total shaders on 1434m transistors on 55nm at about 390mm² die size.

GT200 die size is 583.2mm² on 65nm then the same chip die on 55nm will be about 51% smaller at 385.7mm² and have 197.5mm² free space. From GT200 die pic, the 240 shaders fit a quarter of the pic, worked out nearly 350m transistors and less than 145.8mm² space so it have enough space to pack 240 more shaders on 197.5mm² free space.
