Does AMD use more aggressive optimizations than nvidia does?

I was thinking so but then I don't really know for sure. I heard that HyperZ was more aggressive than nvidia's "early z occlusion culling" and that AMD wanted to use Hyper Z to cull things that could barely be visible as well.

I've never understood what it is that nvidia did to make their depth calculations look better.

What are some vendor specific optimizations (i.e., what does nvidia sacrifice for performance that AMD doesn't and vice versa) at the driver level? What about at the hardware level? Anyone have a list?

As others know, I have a beef with early z occlusion culling because it makes it so that devs are tempted to use depth formats other than 32 bit fx log z.

I have seen artefacts on both vendors cards this year, most likely related to taking shortcuts. The ones a applied to AMD cards with transparency cause major problems with arms 2, the trees gain white speckles which is horrid. But I have seen poor transparency and textures on my 680s as well.

Without knowing the details of exactly what they are doing we can't know if one is more aggressive than the other, and their is no way they could even list them out even if they wanted to.
