looks like something may have changed at allstarshop:

They took out all of the specs.

Also, first leaked benches here

Hmm, I didn't get very far before I stopped reading the flamewar over there.

However, so far nobody seems to be mentioning that the THG review probably has the nv40 using the PS1.1 shader path. So the X800 is <I>really</I> trouncing it.

If you continue reading you will find that all benches were posted.

For those that don't want to look. The X800 Pro is inline with the 6800U in most benchmarks. The X800 XT puts a hurt on the 6800U. The X800 loses horribly in the CoD benchmark(seems like a driver tweak or maybe Nvidias OGL ICD is that much better).

AFAIK PS 1.1 vs. PS 2.0, I think that Nvidia has to use more PS 1.1 but it still uses PS 2.0. That is how I understoood it after reading several forum posts at B3D.

I'd like to see the numbers for Parhelia on the same setup..

Beyond3D's signal to noise ratio has certainly gotten much worse recently.

KvH: I can save you the trouble of waiting to find one, the score is ATi: 1 Gillion, Matrox: 1.

The 1.1 shaders cause some pretty crappy IQ problems. If you force the 6800 to use PS2.0 (by telling the game it's an R300), then these IQ problems go away, BUT the 6800's score drops by <B>20%</B>.

Makes the X800 kick its ass even harder.

You could put a graph up and insert another 25 video card scores and you'd have to scroll a long way down to find the Parhelia.
X800 it still doesnt do triple head.

It still wouldn't be an equal comparison since the 6800 would be doing FP32 vs. FP24. (Unless it's different for X800 now)

[Wombat]

I'm not sure about the FP precision. Still, it's equal enough for me, since it's actually making the 6800 run as a DX9 part, not DX8.1

[Helevitia]

Taken from the B3D review:

The precision of the shader core remains at FP24 per component.

Referring to the X800.

what's the big deal when the DAC's are still at 8 bits per channel?

A higher precision reduces rounding errors. Which results in less visual artifacts.

[Tjalfe]

I still doubt any human can really tell the difference, except perhaps in extreme cases
