All we could confirm at this time is that the chip will be DirectX 10 compliant of course but it won't have the full implementation of Shader Model 4.0. It won't do the unified Shader but it will be Vista ready. Most of the chips out today are Vista ready at least the high end ones. This chip has every chance to end up faster than ATI's upcoming R580+ fall refresh chip but this one will get R600 beast to compete with. It is still too early for clocks and final specs but we will start digging this one. µ |

AS we understand it, if a Nvidia DX10 chip ends up with 32 pixel-Shaders, the same chip will have 16 Shaders that will be able to process geometry instancing or the vertex information.
... The Nvidian chippery is limited to 32 pixel and 16 vertex and geometry lines per clock, which might be a wining ratio but it is still too early to say. We don’t know who will win the next generation hardware game and |

IT TURNS that the fancy Nvidia G80 chip taped out, and in working silicon stage it will have 32 pixel Shaders and, as predicted, have 16 vertex and geometry Shaders. Nvidia wants to stick with a two to one ratio and assumes that the games of tomorrow will need twice as many pixels than they will need vertices and geometry information.

We reported that G80 is a 90 nanometre chip with GDDR 4 support and that it is diss-unified marchitecture |

So, it is going to be late, that is not the ugly bit, board partners are telling us that it very well might have an external PSU to power the beast. |

What they will talk about is the odd part. First is the arrangement of the chip, physically we are hearing that it is 2 * 2 cm, or about a 400mm die. Ouch. One of the reasons it is so big is the whole dual core rumor that has been floating around. G80 is not going to be a converged shader unit like the ATI R500/XBox360 or R600, it will do things the 'old' way.
Some people are saying that it will have 96 pipes, split as 48 DX9 pipes and 48 DX10. While this may sound like a huge number, we are told if this is the case, it is unlikely that you can use both at the same time. Think a 48 or 48 architecture. That said, I kind of doubt this rumor, it makes little sense. In any case, NV is heavily downplaying the DX10 performance, instead shouting about DX9 to anyone who will listen. If the G80 is more or less two 7900s like we hear, it should do pretty well at DX9, but how it stacks up to R600 in DX9 is not known. R600 should annihilate it in DX10 benches though. We hear G80 has about 1/3 of it's die dedicated to DX10 functionality. |

This confirms Nvidia's theory that you don’t need unified shaders, at least for the time being. If the Vole doesn’t care about it, why should Nvidia? The big green company decided to do the different approach as its Vertex, Pixel and Geometry Shaders will still be divided in at last two separate function parts and we believe that this will give some additional speed in DirectX 9 games. That is how Nvidia plans to make its G80 chip and Microsoft doesn’t object. Nvidia will be first to launch a DirectX 10 part with ATI to follow roughly two months after Nvidia introduces its G80 baby. µ | 这个阿Q网的消息来源真是丑完一次又次![]() ![]()
