ATI's New Leader in Graphics Performance: The Radeon X1900 Series

Details of the Cards
There are actually 4 products being launched today, three of which we were able to get our hands on for this article. We have actually spotted all three of these cards we tested around the internet today, so availability is immediate, and we couldn't be happier. As for pricing, ATI's MSRPs are as follows:
Radeon X1900 XTX -- $650
Radeon X1900 CrossFire Edition -- $600
Radeon X1900 XT -- $550
The CrossFire Edition version of the X1900 is clocked the same as the X1900 XT except for its I/O connectors and compositing engine. The X1900 XT weighs in with some very high clock speeds, especially for the number of pixel pipelines it supports. If you are worried about the CrossFire card bringing down the XTX, don't be. The XTX only sees about a 4% increase in core clock speed and a 7% increase in memory clock speed over the stock X1900 XT.
So, while the price gap between the XTX, XT, and CrossFire versions of the card would seem to indicate sizeable performance differences, we can definitively say that this is not the general case. The XTX is only marginally faster even on paper, and, as we will see, in the real world, real performance is what matters. Our advice is to save your money and go with the cheaper XT. 18% more cost for at best 7% more performance is all that the XTX gives.

This test kind of seems biased to me. The cards were tried in CrossFire for the ATI cards, but when it came to the Nvidia 7800 GTX's, 512mb and 256mb, neither were tested in SLI and compared to CrossFire.Anyone have a comparison of SLI vs. CrossFire for the same tests?
DerekWilson - Wednesday, January 25, 2006 - link
For all the games but Battlefield 2 we ran both CrossFire and SLI numbersWe only ran SLI for the GTX 512 because we only looked at the highest end multigpu solution for each series (7800, 1800, 1900).
We would have included SLI in the BF2 portion, but our benchmark doesn't correctly represent gameplay for SLI. We are working on this.
Thanks,
Derek Wilson

Seems weird not to have Sli GT's in there. I still think thats the best deal in highend -around the $550 price point. Should clean up on both the 1900Xt and 1900XTX pretty handily for the same price or less. Is AT still in the business of recommending "bang for the buck"? or moving away from that? Because only .05% of your readers are going go up into the realm of $1000 video cards ( GTX's and XTX's in dual config)danidentity - Tuesday, January 24, 2006 - link
Are the figures in the "Load Power" chart the power consumption of just the video card, or the entire system? If those numbers are just the video card, that's flat out insane.Josh Venning - Wednesday, January 25, 2006 - link
The numbers in the Load Power chart represent the power draw for the entire system under stress testing. Even so, the 7800 GTX 512 SLI and X1900 XTX Xfire setups are ridiculously power-hungry.flexy - Tuesday, January 24, 2006 - link
its nice to see ATI come up with something GOOD after so many disappointments, paper-launches etc.$500 is an "attractive" price (relatively spoken), looking at the card's specs...i am still having a X850XT and (sadly ???) dont really have an "urge" to get this card since i MAINLY play HL2 (full details, even AAx6) and its fast and great even on my old X850XT. Al;most makes me wish i had more game-engines which demand/justify upgrading to this card.
As said..very hapy for ATI and this card is all the way UP on my wishlist (since i am a graphicscard-ho ;).....but then i also know G71 will come and this card will be a killer-card too (from the theoretical speaks). If i had a very slow system and barely could play any games i PROBABLY would get the R580 now... ;)

great job by ATI for bringing out some killer cards. note that a crossfire x1900 system is CHEAPER than 7800 512's. but hey, regardless of who's on top we win :)as far as the parts being expensive - of course they will be, they're top of the line and released today.
i bought a radeon x800pro for $170 and run COD2 at 1280x1024 maxed out (no FSAA/AF) with very few framedrops (worst is scoping in on smoke from grenades). i also have stuttering issues with HDR. minus HDR, i run HL2 @ 1280x1024 6xFSAA and 16xAF. this is coming from a budget system! putting all my components together, my setup costs about 700.

Wow, for that kind of money, you could have almos bought an Xbox 360 bundle...or half a ps3 (har har har).lamestlamer - Tuesday, January 24, 2006 - link
Did anyone else notice how the x1800xt trounced the 7800gtx in almost all tests? A look at the 7800gtx 512 release benchmarks shows the exact opposite. Perhaps the quality settings were on for the 7800gtx while the x1800xt had performance settings. Even the 7800gtx 512 which cannot possibly have a larger than 40% lead over the 7800gtx has a 100% lead in some cases.ocyl - Tuesday, January 24, 2006 - link
It's been mentioned above but I will say it again. While it's okay to say that R580 has 48 pixel shaders, it only really has 16 pixel pipelines.
