Nvidia GT300 specs...

Over the past six months, we heard different bits'n'pieces of information when it comes to GT300, nVidia's next-gen part. We decided to stay silent until we have information confirmed from multiple sources, and now we feel more confident to disclose what is cooking in Santa Clara, India, China and other nV sites around the world.
GT300 isn't the architecture that was envisioned by nVidia's Chief Architect, former Stanford professor Bill Dally, but this architecture will give you a pretty good idea why Bill told Intel to take a hike when the larger chip giant from Santa Clara offered him a job on the Larrabee project.
Thanks to Hardware-Infos, we managed to complete the puzzle what nVidia plans to bring to market in couple of months from now.
What is GT300?

Even though it shares the same first two letters with GT200 architecture [GeForce Tesla], GT300 is the first truly new architecture since SIMD [Single-Instruction Multiple Data] units first appeared in graphical processors.
GT300 architecture groups processing cores in sets of 32 - up from 24 in GT200 architecture. But the difference between the two is that GT300 parts ways with the SIMD architecture that dominate the GPU architecture of today. GT300 Cores rely on MIMD-similar functions [Multiple-Instruction Multiple Data] - all the units work in MPMD mode, executing simple and complex shader and computing operations on-the-go. We're not exactly sure should we continue to use the word "shader processor" or "shader core" as these units are now almost on equal terms as FPUs inside latest AMD and Intel CPUs.
GT300 itself packs 16 groups with 32 cores - yes, we're talking about 512 cores for the high-end part. This number itself raises the computing power of GT300 by more than 2x when compared to the GT200 core. Before the chip tapes-out, there is no way anybody can predict working clocks, but if the clocks remain the same as on GT200, we would have over double the amount of computing power.
If for instance, nVidia gets a 2 GHz clock for the 512 MIMD cores, we are talking about no less than 3TFLOPS with Single-Precision. Dual precision is highly-dependant on how efficient the MIMD-like units will be, but you can count on 6-15x improvement over GT200.

This is not the only change - cluster organization is no longer static. The Scratch Cache is much more granular and allows for larger interactivity between the cores inside the cluster. GPGPU e.g. GPU Computing applications should really benefit from this architectural choice. When it comes to gaming, the question is obviously - how good can GT300 be? Please do bear in mind that this 32-core cluster will be used in next-generation Tegra, Tesla, GeForce and Quadro cards.
This architectural change should result in dramatic increase in Dual-Precision performance, and if GT300 packs enough registers - performance of both Single-Precision and Dual-Precision data might surprise all the players in the industry. Given the timeline when nVidia begun work on GT300, it looks to us like GT200 architecture was a test for real things coming in 2009.
Just like the CPU, GT300 gives direct hardware access [HAL] for CUDA 3.0, DirectX 11, OpenGL 3.1 and OpenCL. You can also do direct programming on the GPU, but we're not exactly sure would development of such a solution that be financially feasible. But the point in question is that now you can do it. It looks like Tim Sweeney's prophecy is slowly, but certainly - coming to life.

WOW!!!.... go team green (though im sure it will cost the same as a small country to own one)

sounds awesome. Glad my 9800gtx+ went defunct and got refunded. I need one of these. At last a large step like 7900 to 8800 was!

Also, no mention of whether its on a 40nm manufacturing process. If it is, might be cheaper to run than current gen cards.

Wow, that sounds amazing, but don't even want to think of the price.

Better start saving some money

Ya I've seen this a few days ago and I'm pretty exited. although I'm thinking that even though they say double the performance. it wont be. I'm thinking it will be somewhere between the 285 and the 295 in performance.. think what the 275 is between the 260 and 280. I think the new GT300 series card will be like a 290.

If the GT300 comes out and they can release a card that is a single card that can do what the GTX 295 does.. and all for around $279.99

I'm There.. but if it's over $400. I wont be happy!

I reckon it will have a good price when first released as I'm thinking they'll price it to compete with ATI cards unlike previously where they just priced it at whatever they wanted.

They said the same about the GTX280 when that came out that it was the power of 2 cards in 1.

I'm hoping for around the same price mark as you as well.

it would be nice for them to ''reasonably'' price this new card....:D

IMO its a classic case of ''trickle tech'' they probably created the GT300 initially & then chopped it up into the ...GTX260, GTX280, GTX265, GTX285, GTX275, GTX295...... & then they release the GTX3xx, but in reality its not new tech at all, the GT300 was sent through the ''chop shop'' so they could string out 6 GPU sales rather than 1.....




SK

You could be right, but then it might have been because they didn't want to do the same as the 8 series where they released the GTX and Ultra and the cards were well ahead of their time as any current game out at that time didn't even stress the card a single bit...until Crysis came out

im waiting they make a low power/good performance video card, so i can put some 3d power on my "not so powerful" generic power supply :P

agreed, i simply cant afford to run current gen higher end cards right now.

Those of you who can afford these (this?) cards, do you honestly see a difference in Gaming FPSs or is it more because you want to have the latest and the greatest?

I mean, with games being Console Ports as of late more than Dedicated PC games (aside from Crisis I think), some better than others and some just crappy, I am wondering if we are not just being taken for a ride.

So far, I have not played a game that I can not maxed out with my lowly GTX260 so I am wondering how much better I could play a game with the GTX300?

hm.... if the gt300 is coming out...... does that mean ati fans can expect a HD5000 series? :D haha looks good btw..... and not a small country.... more like....... england :D haha jk....

Inquirer are basically saying Nvidia are going to fail at this A look at the nvidia gt300 architecture - The Inquirer

But the majority of crap that the inquirer come out with is...well...crap.

The author of this posted a similar article back when the R600 was about to be released saying how Nvidia cards at that time weren't going to get anywhere near the same performance of it. He was wrong.

"But the majority of crap that the inquirer come out with is...well...crap."

amen

...infact, a lot of others are the same, claiming they have reliable source who is maybe just some1 who delivers the mail to where they make the chips.

Exactly. He also says in there himself something along the lines of, "...all news about the GT300 is wrong and inaccurate", so where did he get all his stuff from?

I'm quite happy with my GTX280 Superclocked Edition card.

Don't see a reason to upgrade to this one :\
