Doom 3 Benchmarks at [H]

[BFG10K]

For this reason, nVidia describes the architecture as either 16x1 or 32x0, depending on whether a texturing operation is being executed.

Colour operation, which is pixel or texel. Z/stencil operations execute at a rate of two per pipe.

NV40 can run in a 32x0 pipeline configuration in DoomIII whereas R420 can only do 16x1

The R420 is exactly the same as above and additionally it can also become a 32x0 config when performing MSAA.

Apparently the word is now that this fabled "ground-up" OGL rewrite will arrive with the Xbox2-level GPU (R500?), meaning Spring at the earliest. I wonder if it'll even be usable by current ATi cards?

The delay trend continues. How long have ATi been promising a new control panel?

Anyway what the hell are we doing talking about half life 2 when Doom III will be released in about two weeks!!!

What the hell are you talking about, doom 3 will be release in less than a week (next tuesday)

The release date for me is 13 August so it will be in about two weeks!

IIRC ATI didn't do (Forgive me they might be switched) MSAA it did SS. Also last time i check ATI could do no such thing, and that a Xx0 is Nvidia exclusive.

You are wrong on both counts. The R3xx line and up do MSAA (in fact SSAA isn't even enabled in the drivers) and the R420 can also execute two z/stencil ops per clock like the NV3x/NV40, or two MSAA samples which nVidia can't do.

Yes, except the NV40 is much faster than R420 when running in 32x0 mode with no AA.

We weren't talking about performance, we were talking about what the hardware can and can't do.

The performance delta exists because of ATi's suckful OpenGL ICD.

From what I've read, NV40's 32x0 implementation is much more robust than R420's due to the nature of the hardware design.

I thought you were just saying the R420 didn't even have 32x0? And now you're saying you've read both implementations but the NV40 is more robust?

Humour me then, how is it "more robust"?

You know, we should all get together at a Starbucks one afternoon and talk about video cards "robustness?" Don't forget to bring your laptops so we can talk to one another.
