apokalipse said:I read today that G80 will actually have 128 unified pipelines
Well, maybe it was only rumor then. I read a while back that the R600 would have something like 64 Pixel pipelines, and the G80 only had 32 Pixel pipelines.
EDIT:
DirectX 10 API, which is also referred to as Windows Graphics Foundation 2.0, solves numerous performance-related problems, particularly, it shrinks overhead time spent by API and driver on execution. Additionally, ATI says its first DirectX 10 graphics processor – code-named R600 – will have unified shader micro-architecture, which will allow to boost performance even further compared to currently existing micro-architectures and . The performance improvements are conditioned by a special built-in arbiter processor, which will “tailor” rendering of every frame across the 64 unified shader pipelines. Such an approach, according to ATI, allows to utilize all execution engines within the chip, while in traditional architectures – where pixel shaders and vertex shaders are calculated by dedicated units – some of the arithmetic processors may stand idle waiting for others to complete their tasks.

T 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.
