******************

The information on the nVidia GeForce 7800 Gtx videocard, earlier leaked
out, seems to be valid. Tweakers.net have got hold of the G70-core official
specifications and these appear to be the same as the specs in the rumor:
0,11µ-core with a core speed of 430MHz, 24 pixel pipelines and 8 vertex
shaders. Nvidia renewed the shaderarchitecture in the G70-core, bringing
CineFX to version 4.0.

The performance in games which use Shader model 3.0 will are considerably
improved, says Nvidia. They claim that - with the use of certain shaders -
the performance increase could be as high as 2 times, when compared to the
NV45, particularly thanks to a new design of the texture Units. More
specifically HDR-effects (high dynamic range) with 64-bits floating point
textures.
It is said that Unreal Engine 3.0 will use a lot of these effects to render
lights more realistically. According to our information the card will be
approximately 50% faster than the GeForce 6800 ultra, and score between
18,000 and the 20,000 points in 3DMark03.

Beside better performance, the GeForce 7-series will also deliver better
image quality than the current generation. With what Nvidia calls
Intellisample 4.0; a number of relatively small improvements have been
introduced in the field of anti-aliasing (AA) and anisotropic filtering
(AF). Also the video decoder is tweaked for better performances and quality.
Furthermore Nvidia claims that the new architecture is compatible with
Longhorn.
Most likely Nvidia is talking about "Windows Graphics foundation (version
1.0)", which means - among other things - that the chip can do
multithreading.

The card - which the slogan gets "Full Throttle Graphics" - will be shown at
Computex (31 May up to 4 June) by Asus and MSI, but it is unclear if nVidia
will announce the new chip there too. Earlier rumors about Nvidia's official
accouchement spoke of 22 June.

Finally we can present a photograph of the new card. Note the compact
cooler, which seems to take up only 1 slot. Although the information on the
requirement for a 400 watt PSU seems correct, however, the warmth
development possibly turns out better than expected.
