The GT300/Fermi Thread - Part 2!

Ummm... setup doesn't care about AFR/CF/SLI, it will scale accordingly.

I'm not sure what to say about triangles. Over at B3d, they brought up the fact that 2 x 5770's beats 1 x 5870 in triangle intensive games like HAWX, which the GF100 was benched at as being pretty fast. Supposedly 2 cards means twice the tri/clock?

Thanks Fellix. So the Shader units & Texture units are different speeds, are they separate domains?

I think he meant that shader and texture units are tied together - but texture units operate at half the speed of the shader domain, hence a 2:1 clock ratio of shader:texture

This makes sense from what people have been saying - the GF100 has a lot of tesselation / triangle/clock power, but it's texture and ROP performance is not much better than the GTX285... meaning that in games that rely on texture and ROP performance, it's performance is not much better than a 5870 if at all, but in triangle/tesselation intensive games, it is much faster than the 5870. This is corroborated by the evidence in benchmarks - HAWX (a tri intensive game) sees the GF100 perform much much faster than the 5870 but the quoted average % increase over 5870 is a lot lower than the specs would suggest, meaning that in other games heavy in textures and/or ROPs it doesn't perform much better if at all. We'll see soon enough, but that's the latest story
