It's a pretty safe bet the gt200 will roughly double the performance of the original g80. The exact number of individual units isn't really important to me, as long as 1GB of mem is an option, with sufficient bandwidth to go along.

Physx processor? idk.

Shaping up to look like a nice card. Sure will be nice to see a 512-bit interface.

 

[Continuity28]

Ignoring cost, which would have a theoretical performance advantage between 512-bit GDDR3 and 256-bit GDDR5?

What I want to know is... when is the NDA going to lift? Can someone under the NDA disclose the date at which the NDA lifts?

Heh- taltamir FTW!

Can't tell you when NDA lifts either, because it's the same as launch day in the era of hard launch.

All the news of this that's left will get leaked soon enough, just not by me.

Will your PO box, the one where the engineering sample will ship to, accomodate a case of the stuff?

A fair trade, just need to know where to ship to...

Um...I think that you're WAY off base. Both nvidia and amd have been struggling to beat the original g80 at all. The current leader, 9800gx2 is what, 30-40% faster on average than 8800gtx. You really think that gt200 will be 50% faster than 9800gx2??? No offense, but that's plain crazy talk!

That would be short in Canada.

If GT200 isn't 2x faster than G80, then it is a huge failure. 9800GX2 is already ~40-50% faster if not more, and R700 should be considerably faster than the 9800GX2.

By the time GT200 ships, it will have been nearly 2 years since G80 came out... 2x performance after 2 years is actually very bad considering the way the graphics industry usually moves.

Hmm.

I dunno.

X1900XTX>R600>HD3870, are we 2X faster yet? No.

GF3>GF4 2X faster? No.

Seems to me in the NVIDIA world we more often get previous gen SLi performance-
6800GT SLi ~ 7800GTX
7800GTX SLi ~ 8800GTX

I hope the GT200 is twice as fast as a 8800GTX, but personally, I doubt it will be except perhaps in some situations.

You have to remember the GTX is at a level of performance the 4870 might just see now, and personally I doubt the R700 will be significantly faster than a 9800GX2.

Bandwidth has never been the R6XXs problem, and adding another cluster of VLIW shaders and doubling the TMUs isn't going to all the sudden make that core twice as fast across the board.

Likewise if the GT200 rumors are true, going from 24>32 ROPs, 384 bit to 512 bit, etc shouldn't make the GT200 2X as fast across the board. (not that I hope it doesn't)

Personally, I think 9800GX2 level performance on one chip, from ATi or NVIDIA, would be pretty great as I'm loving my GX2s, and I know there are some who won't do multi GPU.

M y $.02, but I think double the performance across the board would be surprising and phenomenal.

P.S. It's been exactly 18 mos (1.5 years) since G80 launched. If the GT200 launches soon, it will be far closer to a year and a half than two years.

The 2900XT is faster than the X1900XTX, but a good margin most of the time, I can personally attest to that, having owned both cards. The benchmarks back me up as well.

The 2900XT and 3870 are within spitting distance of each other most of the time as well. The 3870 just consumes less power and costs AMD substantially less to manufacture.

The gt200 should spank the 9800gx2 across the board, and if it doesn't, then what's the point of releasing such a product? To have yet another g92 derivative? The sandwich card is just a stop-gap solution, as was last gen, to have something faster until a next gen high end card is ready. As impressive as the g80 seemed 18 months ago, based on Moore's Law, it's about time we got double the performace, and so far the trend held up without resorting to sandwich cards as a long term solution. You people need to realize that we now have cards for under $200, sitting uder a pathetic single-slot cooler, which offer performance on par with the old g80, and if you think Nvidia can't make a gpu that comes close to doubling that performance, then I have a bridge to sell you. Whether they will is another question, and hopefully the rv770 will push Nvidia in the right direction.

I think you are misreading what he's saying... It probably should have been:

X1900XTX->R600->HD3870, are we 2X faster yet? No.

He's not using the "greater then" symbol to represent the X1900XTX as being superior to R600. He's showing progression, and stating (correctly) that the HD3870 is not twice the performance of an X1900XTX.

6800GT SLi ~ 7800GTX
7800GTX SLi ~ 8800GTX

This seems about right IMO. I imagine that 9800GTX SLI ~ GT200 up to 1600x1200, and then at 1920x1200+ the increased memory bandwidth and vRAM should make a single GT200 pull ahead of 9800GTX SLI, especially with AA.

Yep- you get me Nitro.

Contrary to popular belief, there's ALWAYS a reason to make a single GPU solution that performs as well as prior gen high end SLi:

You get that level of performance across the board without multi gpu issues.

In any case, I can pretty much guarantee whatever GT200 is, it won't be a "big failure". There are many people looking for a new high end single gpu solution that are going to buy these like crazy, because there probably won't be any single gpu competition.

So, the mechanical drawing if true definitely tells us several things.

-16x64MB of GDDR3 memory (1024MB total), where 2 memory chips are partitioned with a 64bit channel to a combined total of 512bit memory interface + 32 ROPs.
-Separate NVIO chip probably due to the large die size.
-Im guessing its on 65nm process (i.e resulting in the use of NVIO chip), its going to be one monolithic die. Also the return of the IHS. Possibly the NVIO is integrated to the GPU when the 55nm GT200 refresh comes. (similarly with G80+NVIO ->G92)

Im still wondering though. Will this GT200 be radically different to G80/92 architecture, or share the same fundamentals? If they share the same architectural traits, GT200 could still be DX10.

I would agree with your inference on the mechanical drawing. If indeed it is 512bit, 32 ROP separate NVIO chip then I can only dread the power consumption and heat output from such a thing, especially if it is still on the 65nm process. I would think it would make sense for this to be fabbed on 55nm, I mean it is TSMC who fab ATI's 55nm RV670 GPU and TSMC also fab Nvidias GPU's aswell, I would hope the process has matured enough and Nvidia can produce a High end product on 55nm- If not we might have another R600 on our hands in terms of power consumption and heat output.

 

[BFG10K]

Fudzilla are claiming nVidia are trying to tape out both 65nm and 55nm GT200 chips with the 65nm version to be used only if the 55nm version fails.

They're also claiming a June launch.

 

[Cookie Monster]

I dont think nVIDIA will ever risk using a newer process for the next gen products. (Ever since the NV30 fiasco i.e the use of 130nm)

8800 GTX SLI ~ 9800 GX2 "about"
9800 GX2/ 8800 GTX SLI ~ GT200??

SO you can buy a $600 card now and get about the same performance as a new GT200 which will cost abou $500??

 

[Cookie Monster]

The thing is that a multi GPU configuration will always have more drawbacks. They aren't going to reach x2 performance over a single card as the scaling will vary from game to game.

Scaling however isn't the only drawback of a multi GPU setup compared to a single GPU setup.

And id think 8800GTX SLI is abit faster than the 9800GX2. A 9800GX2 is simply 2 8800GTs sandwiched together to work as a single PCI-e slot card. (a 8800GTX is faster than the 8800GT).
