View Full Version : X1800 XT/Pro Review
OWA : Those were in older drivers .. in the newer drivers ATi's performance in Doom3 improved.
however i dont find the numbers fishy since they used a "custom" benchmark not the regular timedemo or one of Xbits benchies.
that custom benchmark probably stress the parts where nVIDIA's advantage can be experianced more than other benchies & stress the cards overall (just like VIA VGA's benchmark).. hence the GTX/SLI performance which looks to be weak if compared to other map/timedemo benchmarks.
Okay. I didn't read the article, just grabbed the first graph I found when searching so my bad on that.
That is the X800XT PE not the X850XT PE. That was also before the Catalyst AI was introduced which put the X800XT about on par with the GT.
Yeah, sorry about that. I should have paid more attention to what I was posting.

It could be possible they turned off cat ai.

That wouldn't cause a 30% drop in performance and put the X850XTPE that far behind the GT.
ATI's (Chris Hook) first reaction to this article was: " Fiction. I don't believe these numbers were ever run on a 520 ".
Well he would say that wouldnt he. :rolleyes: Lets just wait for the offical benchies.

oh yes it would, without the shader replacement the x850xt is around the same fps as a 6800nu in Doom 3
these benchmarks are plassiable, unless the reviewer really went as far to cover his own tracks, since MSI threatened to leave ATi not too long ago, got the inside info from them.

No its not. I've owned a X800XT (500/500) which has a much lower clock than the X850XTPE. The performance drop was, at most, 10% with AI disable. Even with AI disabled it wasn't all that far behind the GT I had before it (by that I mean the difference in-game was fairly small).
Agreed. My ultra OC did not feel any faster in d3 with the new cat's and AI.
OTOH, dx games feel a lot snappier with the xt :D

well DH doesn't think so, and its a pretty ATi + site

I'm not sure at all about those benches but more important than the actual numbers are the looks now on peoples faces over at rage3d .. priceless :D
heh heh.

yeah this is amusing whether real or fake.

What is the Catalyst AI?
What is the Catalyst AI?
You own an XT-PE & you dont know the Cat A.I!!
the Catalyst A.I is the tool for the filtering optimizations. you can say it equals nVIDIA's AF opt 3 tabs.
for games that are specified in the A.I. list within the drivers the performance would increase when A.I. is enabled without noticing these optimizations or affecting the IQ generally .. hence the name A.I. & i should say its doing a pretty good job at it.
though for best IQ with no opt (full trilinear) you have to disable it.
its enabled @"Standard" (or low) by default & can be turned to "Advanced" (or high) from the driver CP for higher performance but expect lower filtering/IQ or you can disable it at once which will reduce your performance but result in best filtering quality possible.

You must need catalyst control center for this. No wonder I don't see it in my driver options.

You can see it with ATitools if you dont use the CCC. its added in the latest version.

I don't care what DH thinks. I've had personal experence with both cards. Just believe whoever ya want.

You own an XT-PE & you dont know the ATI Tray Tools?!!
Ok fixed. I couldn't imagine having an ATI card and not ATI Tray Tools. It adds sooo much functionality. Just get it. You can thank me later. :P

You know whats funny, the r420 has a slight edge on the nv40 and no one here complained OMG NVIDIA LOST. Now the tables have turned and the ati camp is going bonkers.

Oh god, the ATI camp have turned it into a **** storm pretty much.
Accusing Ratchet of having an "agenda". It's all Bush's fault!!!! :werd: to zak though, honestly their reactions are just hilarious in all this :D
As noted by shabby, the reactions here were NEVER that drastic.
Back on topic, I can't quite figure out what to htink of this quote from Chris Hook at Guru3D.com This is a complete hoax - done with an OC'd X850, we think. Call our partners yourself and ask if they have R520XTs in house. The numbers aren't even close.
If I am reading this right, the AIBs don't have R520 XTs yet? I suppose all of the XT speed-binned chips could be retained by ATI for "their" cards. Also leads one to believe the XT launch will not be a hard launch.

"hard launch"? As in difficult or as in another paper launch?

Heh, funny. I meant opposite of paper launch.

it seems that Hardware Analysis was not that far off with its results after all.
here is another website doing X1800XT benchmarks and their results are pretty close to HA's results.

They are posting benchmarks, but they don't know how many vertex units it has? Where are you ATI? Even if its a paper release, announce something.

Is it really that hard to come to the conclusion that none of this is being sanctioned by ATI? Why would they need to announce anything?
