Nvidia G80 specs leaked

[Biodoid]

Earlier today some information regarding the possible specs of nVidia's upcoming G80 based boards surfaced on VR-Zone, only to be \"quietly\" removed later. Thankfully X-bit labs managed to collect the information on the new cards and we can now present it to you below.

The most important aspect of the leaked documentation are the specs revealed:

- Unified Shader Architecture;
- Support FP16 HDR+MSAA;
- Support GDDR4 memories;
- Close to 700M transistors (G71 - 278M / G70 - 302M);
- New AA mode: VCAA;
- Core clock scalable up to 1.5GHz;
- Shader performance: 2x Pixel/12x Vertex over G71;
- 8 TCPs & 128 stream processors;
- Much more efficient than traditional architecture;
- 384-bit memory interface (256-bit+128-bit);
- 768MB memory size (512MB+256MB)

The unified shader architecture suggests, what the experts have been saying for a while now, that the cards will be support DX10.

According to the same, leaked, information the G80 will surface in November in two varieties, the GeForce 8800 GTX and GeForce 8800 GT priced at a mere USD 649 and USD 449-499 respectively. The GTX model (higher-end) will feature a 384-bit memory interface, a hybrid water and air cooler and 7 TCPs while the GT will have a 320-bit memory interface, a standard air cooler, and 6 TCPs.

No one has actually explained what TCP actually stands for although Techreport has uncovered an nVidia patent which refers to thread control processors. According to the same patent these TCPs will be used to set the function of the unified shader processors.

I was wondering how many shaders it will have. The new R600 ATI chip will have 64 unified shader.

I am waiting to buy a DX10 card and won't choose until both chips are released. They reckon the new ATI chip will give the graphics card crown back to ATI.

Give it back......... didnt realise they'd lost it.

Still prefer my 7900GS to my x1800xt though.

nVidia has officially named its G80 chip and announced the first two boards to carry its architecture, the GeForce 8800 GTX and GeForce 8800 GTS, revealing their hardware specifications.

The anticipated launch for these cards is November 8, 2006 although the company has not confirmed that date.
The GeForce 8800 GTX will serve as the flagship product for the company and will support DX10 and shader model 4.0 as we expected and will feature a stunning 128 pixel pipelines, a number which becomes even more impressive when considering that the current pipeline peak is the 48 found on ATI's X1950XTX and that the current nVidia peak is the 32 on GeForce 7900GTX.

The full GeForce 8800 GTX specs are:

GeForce 8800GTX
Core clock: 575MHz
Pixel pipelines: 128 @ 1350 MHz
Memory: 768MB DDR3 @ 900 MHz
Memory interface: 384-bit
Memory bandwidth: 86GB/s

The GeForce 8800 GTS will be a lower end model but only when compares to the GTX as it will still feature 96 pixel pipelines. The GeForce 8800 GTS full specs are:

Core clock: 500MHz
Pixel pipelines: 96 @ 1200 MHz
Memory: 640MB DDR3 @ 900 MHz
Memory interface: 320-bit
Memory bandwidth: 64GB/s

The company has also issued recommended power ratings for these new beasts as they will feature two PCI-Express slots in order to receive the juice they require to run; a 450W power supply will be the minimum requirement for a GF 8800 GTX and a 400W for a GF 8800 GTS. If you have more money than sense and decide to run two of these babies in an SLI setup you will need a minimum 800W power supply.

DX10 games are unlikely to surface before 2007 and around Q1 of the same year ATI plans to introduce its own DX10 offering. The Canadians are running a little behind their rivals although this seems to be a repeat of the Shader Model 3.0 support saga. The question now is; how many people will be willing to buy DX10 cards before Vista (the only OS to support DX10) and games featuring the technology are available?

I want 2 8800 GTX's :twisted:

and a small nuclear reactor to power them
