Man look at that, at techreport the X1800 XT destroys the GTX in far cry!!!

You know whats funny. At Tomshardware the benchmark for Farcry is a TIE.

As Jack Palance used to say, believe it or not!!

theres bound to be some fluctuations but thats a pretty big difference in the 2 sites.

I found this interesting

I have to draw your attention to the fact that we haven?t found any real evidence pointing at the significant advantage of the enhanced AF mode over the standard AF mode. In other words, there is no big difference in the image quality of real games between the enhanced anisotropic filtering mode of the new RADEON X1800 XT and the standard anisotropic filtering of the new ATI solutions as well as of the other graphics cards.



So, the laurels for the best FSAA quality, in at least certain cases, will remain with NVIDIA for now.



So much for the supposed IQ superiority of the X1800XT.

btw reading more of this and it is interesting the synthetic shader results.

Its good to see some video decoding testing, although some Transport stream playback would have been nice since its far more demanding than DVD testing they did, and no mention of H264. Looks like a driver issue for Divx also, and the Divx player supports acceleration on Radeon cards, so that should have been tested as well.

Some IQ comparisons would have been nice.

The Far Cry results are difficult to interpret as they are running different settings, different benchmarks (Pier, Volcano, Cooler, ...), and diffeent CPUs (FX-57, X2 4800, etc.)

Did you see this? I'd say that's a pretty big IQ difference in a real game, unless you're blind.

Hardocp:
"With high quality AF enabled on the X1800 XL, the bottom of the angled wall is very smooth with no blurring. This really shows you the benefit of high quality AF; all angles are filtered "properly" with anisotropic filtering. This provides a very noticeable image quality benefit in game. "


Also, at 2xAA, the x1800 has better transparency AA than the 7800.

Hardocp:
"There is a large difference, in our opinion, at 2X AA as the Radeon X1800 XL is producing better image quality. "

Angle dependent AF will do this and ATI is not immune to it either. I have seen this on NV30s, R300s, NV40s and R420s.

I am curious which driver revision he is using and if it is really in High Quality mode. afaik high quality mode brings back the AF filtering we had in the NV30 where it wasnt nearly as angle dependent as it is in the NV40, G70,R300,R420, and the newest R520.

Today we saw that the Shader Model 3.0 support was really done for good: just look how the RADEON X1600 XT manages to leave behind a far more expensive and enhanced GeForce 7800 GTX during dynamic branching and pixel shaders 3.0 processing. In addition, ATI?s new RADEON X1000 family copes perfectly well with multi-pass rendering, and full-screen anti-aliasing, according to our preliminary observations.

Wow if that is true, I'm getting an X1800XL. :thumbsup:

Checking all the review websites is that they are using a beta driver for all the testing. And some other diffferent Catalyst drivers for some reason.

Maybe things will change slightly when its out properly.

AF- From what I have seen so far the 1800 series parts seem to be considerably less angle dependant then the NV30s ever were(and obviously vastly superior to anything we have seen since). Based on the mip analyzation results that I have seen it looks like it may be comparable to the NV2X line of parts which to date have been far better then anything else.

In that circle AF test the more circular the rainbow the less angle dependent the AF is correct?

The more uniform. While a perfect circle would be ideal, a square shape would be more accurate then an oval.

Unless you disable it that is, which the X1800 allows.

Why would you disable it- it doesn't make a difference and the performance hit is huge- you told me that yourself :)

Edit- Forgot, the performance hit gets 'cumulated' when used with AA too- all things you told me :D

Regarding the performance hit, we really need some 2048x1536 benchmarks with it enabled and disabled to actually see the true impact. I'm actually disappointed with all of the rushed reviews we've seen - very little games with a few low/middling resolutions and that's it.

As for the algorithm, I doubt it's exactly the same as the NV2x. More than likely it just mimicks the IQ somewhat.

That is my point. With so much to compare and talk about, a couple of benchmarks under 1600x1200 and that's it.

The previous generation was good enough for 1600x1200. I wanna see 1920x1200 and up plus real life quality comparison - and the shimmering issue.....

Hardware.fr has 19x12 numbers. (It's a French site, but an English translation will appear soon enough at their English sister site, BeHardware.com. In the meantime, the graphs need no translating.)

Edit: TrustedReviews has 19x14 and 20x15 numbers, but only for the XL and GT.
