View Full Version : 6800U 16x1, 6x1?

Dumb question (but still like to know the answer ). RivaTuner 2.0 RC15.1 version and Leadtek 6800 Ultra.

What's the meaning of this? Please see attached picture...

When I access nVStrap Driver, and choose Custom graphics processor config, it only shows me 6 vertex units and only 4 pixel units. Does anyone know why? Shouldn't it show me 16 separate pixel units, because it's 16x1? Why does it only display 4 pixel units instead of the whole 16? It's like 4x4 or something?

Although in the main panel it displays the information as should be: 256-bit NV40 (A1, 16x1, 6vp) with 256 MB DDR.

Each Pixel unit in the list represent 4 pixel pipelines (Quad-bumped as MYUA likes to call it :p ) .

4 pixel pipelines are divided into quad architectures on modern GPUs, Quads can be enabled or disabled, But you cant get pipes seperately.

Thanks guys for sharing! So it's "quad-bumped"... like 4x4.

Hey Chris, thanks a bunch for those "old" nVidia AA modes for RivaTuner... Great job! I'm really happy with 4xS AA mode... coupled with 8x AF it really shows some good results with NFS HP2 and NFSU.
