hi!
i’ve a simple question,does x800 support floating point blending like nvidia 6800?
thanks in advance

Almost certainly not.

You see, that would have required actual work and effort on the part of ATi. They decided not to do any actual work with the x800, and just re-released the 9500+ line with more vertex and fragment pipes.
Oh, and 3Dc. Let’s not forget that :rolleyes:

If you want features, get a 6xxx FX card.
No it doesn’t support floating point blending, as Korval said 6800 is offering this feature and I think that 3DLabs with its Wildcat Realizm series can also do FP16 blending.

Running it on 300W Antec. GT version, but for development purposes, 10% difference in clock speeds won’t make any difference.
Power supply “requirement” is a simply precautionary step by Nvidia, in order to avoid lawsuits when Generic 400W PS with 10VA on 12V rail purchased from CompUSA blows up

Actually, it’s more of the quad version of 9600 series (w/higher instruction count to qualify for another useless update - DX 9b)

yooyo

The WR can do more than FP blending, in fact it can directly show 16-bit per channel FP frame buffers.
I’m disappointed by the X800. I would have loved to drop all this ping-pong rendering thing.
By the way, I like NV4x and HDR blending but I still won’t buy them in the short run.
Too bad 3dlabs chips are not mass-marketed.
Looks like HDR blending won’t be for the masses for a long time. Sigh.
