And NVIDIA will never make such mistake even on their prototype or A0 silicon cards.
This is 100% fake.
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)â€, 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.
According to our sources, the card is hot, so hot that we did not managed to even perform a live run. The card is obviously damaged due to heat and upon closer inspection, we saw brown burnt marks around the card, near the PCI Express connector and even at the fan plug. The 10-layer PCB which holds the GPU also suffered heat damage and we saw blistering of the PCB at areas near the GPU.
The card will draw, *drumroll*, a total of 150W. That's even more than any regular desktop CPU we know. 75W will be drawn from the PCI Express interface while another 75W will be supplied through an extra power connector on the card. This will pose as a challenge to graphics card manufacturers as they start designing the appropriate cooling solutions for their card. It doesn't look like it's going to work as a single slot solution, but we'll never know for sure. If NVIDIA is going to deliver the G70 in bulk, they'll need to get their manufacturing partner to further refine their manufacturing process and decrease its heat output. Sources tell us that the G70 is manufactured using 110nm process technology and not 90nm as earlier speculated.
