Acham que haverá grandes diferenças de performance entre as 8800 GTS 320mb para a 8900GS 256mb ? Se for possivel digam um exemplo que seja "previsivel" em relaçao as graficas da serie 7 para compreender melhor :P

Tinha na mente comprar a 8600GT mas aqueles 128 bit deve deixar muito a desejar nao ?
 
Olha só, o The Inq a ser surpreendido:

Geforce 8900 GTX has 25 per cent more shaders


Everything is under the curtain. Yeah, curtain


NVIDIA managed to hide some stuff in front of our eyes, under a veil, curtain or purda.

If Geforce 8900 turns out to be using the G80 chip, that will mean that the chip had more Shaders all along. Our sources confirm that Geforce 8900 GTX has more shaders.

We know that this will speed up some of the games and definitely in the "scientific" GPGPU calculations. We heard that the card still has the same G80, 90 nanometre core but Nvidia might be veiling some info. We know you cannot clock the G80 more than 630MHz unless you "goto" water cooling. With that you are still topped at 680+MHz.

We heard that the card will be announced just in time to spoil the ATI's fun with R600 launch. Quel surprise, n'est ce pas? µ



Resta saber que "fontes" são essas que ele cita constantemente nas notícias sobre a Nvidia, que nunca acertam em nada (G71 com 32 Pixel Shaders, G80 não unificada, etc)...

Pois...mas se isso fosse verdade, tá-me a parecer que vendia a minha 8800GTX e comprava uma destas :D

Mais 25% de shaders dá 160 shaders :004:

Sim, 32 shaders de diferença (é o mesmo nº de shaders que separa a 8800 GTS da 8800 GTX).

Suponhamos:
- 160 shaders (mais 32)
- SP's a 1500MHz (mais 150MHz)
- Core a 630MHz (mais 55MHz)
- GDDR4 a 2200MHz (mais 400MHz)

Pode dar uma diferença "potente" em relação à 8800 GTX, e sem ter de mudar de core ou de bus...

Nvidia beavering away on a Geforce 8950 GX2 card

http://www.theinquirer.net/default.aspx?article=37634


CUDA is Nvidia's name for a GPGPU.

The acronym actually stands for Compute Unified Device Architecture). The CUDA marchitecture is apparently a fundamentally new computing marchitecture for the GPU to solve complex computational problems across consumer, business, and technical industries. At least that is what Nvidia says about it. And CUDA demands a dual Geforce 8950 GX2 as this means more computation power.

Nvidia entered this market later than ATI but it still has a lot of success as it has G80 that can do a lot of pixel and Shader operations. G80 is still the fastest graphics chip on the market. It has 128 Shaders and can process a lot of pixels. Therefore it is good for GPGPU or CUDA calculations as these science calculations are run on a graphics card disguised as a small Shader programs.

As G80 has 128 Shaders and apparently Geforce 8900 GTX is supposed to have 25 percent more Shader power, the new Geforce 8950 GX2 card should provide a lot more Shader and Pixel power. The card is demanded and we believe that Nvidia already has the design but we don’t know about any possible announcement.

If Nvidia ever sorts out its quad chip driver this means Quad G80 could be on the horizon - or however they later call this product. Yeah, graphics chips these days are big, hot and crazy. µ
 
Geforce 8900GTX and 8950GX2 details listed

With 8900 GTS and 8900 GS at 80 nanometres


JUST A DAY after we uncovered the existence of Nvidia's Geforce 8950 GTX and Geforce 8900 GTX, our friends in Taiwan confirmed the news. You can read our original stories here and here.

The Geforce 8950 GX2 is a dual-chip card based on a new 80 nanometre G80 chip, probably codenamed something else. Both GX2 GPUs are clocked at 550MHz and the difference is GDDR4. The card comes with 2x512MB of 256-bit GDDR4 memory clocked at 2000MHz. The card has 96 Shaders, per chip. It will be priced at $600.

The second in Nvidia's spring line-up is the Geforce 8900 GTX clocked at 700MHz GPU and 2200MHz memory. The chip still has a 384-bit memory interface and comes with 768MB of memory. The card uses a new 80 nanometre chip and has 128 Shaders. Compared to the Radeon X2800XTX it will end up shorter on clock and memory interface. You can compare them here.

The Geforce 8900 GTX is priced at $550.

Meanwhile, the Geforce 8900 GTS is a new card clocked at 600MHz GPU with 2000MHz GDDR4 memory. It supports the 320-bit memory controller and comes with 640Mb of memory. This card should cost $500 and it is using the 80 nanometre chip. This card will still have 128 Shader units.

The current king of the crop, the 8800 GTX will drop in price to $450, while the Geforce 8800 GTS loaded with 640MB of memory stays up in the $400 price range.

Nvidia has two more 80 nanometre cards. The Geforce 8900GT with 600MHz core and with a 256-bit memory interface comes with 512MB of 1800MHz GDDR3 memory. It has 96 Shaders and is built on a 80 nanometre process and will cost $400.

The 8900 GS will be the cheapest G80-based card. The 80 nanometre based beast is clocked at 550MHz core and 1600MHZ memory. The card has the 256-bit memory controller and comes with 256 or 512MB of GDDR3 memory. It also has 96 Shaders. The 256MB version will cost $200 while 512MB incarnation will end up at around the $250 price mark.

The apparently-leaked document mentions G84 and G86 chips but we have some details to confirm. The original story with document is here. µ

NVIDIA has Five New Cards in the Works


techPowerUp! has already reported on NVIDIA’s 8900GTX, which is essentially an overclocked version of the G80 with 25% more shaders unlocked, but NVIDIA is also planning a dual-GPU card, the 8950GX2, as well as a GTS version and budget GT and GS models. Because there are so many details, here’s a list:


8950 GX2 - this will have two cores working at 550MHz with 96 shaders on each chip, and two sets of 512MB 256-bit GDDR4 memory at 2000MHz and a predicted price of $600.

8900 GTX - this is now being reported to run at 700MHz with 128 shaders and 768MB of 384-bit memory running at 2200MHz, priced around $550

8900 GTS - this version will be similar to the GTX, with 128 shaders but a lower GPU speed of 600MHz and 640MB of 320-bit memory running at 2000MHz. The price should be around $500

8900 GT – this will have 96 shaders and a 600MHz core, with 512MB of 256-bit GDDR3 memory running at 1800MHz, priced around $400

8900GS – this should have a core clocked at 550MHz with 96 shaders and 256-bit memory at 1600MHz in sizes of either 256MB or 512MB. This should cost about $250




All five of these cards will use an 80nm manufacturing process and could push down the price of the 8800GTX to $450 and the 8800GTS to $400.

Isto é tudo muito bonito e quanto mais melhor mas...mas...e jogos para isto? É que honestamente eu só vejo placas a sair, a r600 aì à porta, as novas nvidia na primavera...mas jogos que é bom nada. O crysis cada vez é mais adiado...o bioshock não leio novidades há imenso tempo.

O único jogo que acredito que as novas placas venham ajudar é o Rainbow Six Vegas em widescreen, e especialmente pela má optimização, nem tanto pelo Unreal Engin3.

Ok ok e as gamas mais baratas também são benvindas, para todos poderem ter placas DX10 :x2:

Cumps,

hey... estas gráficas tb são boas em directx9... neste momento jogo fear com tudo no máximo e bem fluído, coisa que não acontecia com a minha anterior 7800gt... o directx10 é só um bonus por enquanto :D
 
NVIDIA Demo: Cascades (GeForce 8800) DX10 DEMO

FEATURES:
Microsoft DirectX 10: Every aspect of the Cascades demo demonstrates next-generation features enabled by DirectX 10, including the generation of content, dynamic particle systems, and the high quality rendering of the scene.
Procedural Geometry Creation: Rock structures are not only rendered, but also constructed by the GeForce 8800. This permits the user to move up or down forever, with the GPU continuously streaming out colossal chunks of rock in a wide variety of random shapes.
Dynamic Particle Physics: The GeForce 8800’s geometry shaders perform all the physics calculations for the water, allowing the waterfalls to collide with the rock surface and to form rivers flowing around the features of the rock. Water particles are generated, propagated, and retired on the GPU, leaving the CPU free to perform other tasks.
Displacement Mapping: Improved displacement mapping techniques use a simple height map in a complex pixel shader to display detailed cracks and bumps that are able to occlude each other, resulting in an extremely high level of realism on the rock surface.

Download - http://downloads.guru3d.com/download.php?det=1580

Explore a fantastic new world of endless rock formations and exhilirating detail. Watch majestic waterfalls cascade down the rock, while buzzing swarms of dragonfly-like inhabitants dive and play. Zoom in close to examine the vibrant surface detail, or move the camera up or down to explore the rock’s infinite outcroppings, cliffs, and caves.

Sit back and watch as the camera follows the water down as it flows over the rock, falls through the air, and crashes back onto the rock below in a cloud of mist. Or, take control and interactively place your own waterfalls on the terrain to create a beautiful personalized dreamscape just the way you want it.

Infelizmente ainda n estou para instalar o vista...mas quem ja o tiver instalado, e tiver uma 8800 ;)
