Error #1: the x800 series is not the only series that supports 2.0b. I believe it goes back to the 9500/9600 for 2.0b support.
Also, the 9800 "pro" that they listed, is now called the 9800 atlantis.
Another thing: isnt super sampling a form of AA? He writes as if its not in the article.
If i understand this right, then hes saying that due to the presence of 3dc on the x800 series, that 2.0b was not made into a standard because 3dc isnt included in sm3.0. So 3dc is part of sm2.0b? I thought it was just a feature (like trueform is) and isnt included in the spec.
"Going back to ATI for a minute, it becomes a little clearer why ATI's SM2.0b isn't an official Microsoft standard. SM3.0 already supersedes it as a standard, and yet certain features of SM2.0b as ATI defines it are not present in SM3.0, for example the new 3Dc normal map compression. Only time will tell if this feature gets used with current hardware, but it will likely be included in a future version of DirectX, so it could come in useful."

Yea what the guy said above, and i thought 3Dc was an open source thing too...
Also the reason why 2.0b wasnt choses was becuase of Geometry Instancing, and that was the sole reason for not being WHQL...

Marsumane, I don't think the 95/9600 Radeons do have PS2.0b capability. And the 'Atlantis' suffix for the 9800 Pro is just a Sapphire thing. ATI still calls it the 9800 Pro. Supersampling IS a method of AA.
Lots of mistakes all over the place in the article, but for the most part it gives people the right general idea. One thing I didn't like-
GF2U and GF3 were $500 parts when they launched, this in a paragraph where they were talking about rising costs(which just isn't true unless you consider 6800U/GTs SLId). The rest of the mistakes I noticed on my first quick readthrough were mainly technical(there are a lot) but the article gives people a good general idea anyway.

I bought a VisionTek GF3 the week it came out for $330. IIRC, there were rumors and much speculation on web boards about $500 cards, but the GF3 launched with a typical street price of ~ $350.

That was a pre-release article. Again, there was a lot of speculation of a $500 price. It didn't happen.
No matter what the articles state, in reality the GF3 original never cost $500. If there was a plummet, it happened before the card launched. People were buying them for below $350 the week they came out.
The 6800 also supports high dynamic range lighting, and displacement mapping which were showed off to great effect in the unreal 3 engine demo - aren't they directX 9c?. These are probably the key features for improving next gen games graphics quality and are not in the X800 series, which other then 3Dc can just give some of the d9c performance improvements. Unfortunately for ati I suspect 3Dc won't be properly supported till the next direct X.
Incidentally for the person that asked super sampling is a form of anti aliasing, and does a better job then multi-sampling (because it can anti-alias textures with transparency e.g. leaves on plants in farcry), but takes more grunt to do (so even with a 6800U you couldn't use it in farcry, but I suppose you could if you still like playing old stuff such as original counterstrike, or day of defeat).
Isnt saphire the only company to have the 128bit bussed 9800's? I didnt think ati had their own model. Also, the 9500 is basically an underpowered 9700 core i thought. Therefore they support 2.0b. Im not 100% sure on this, can anyone clear this up?
