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.

$500 too much? there are cars for $300, 000+, but u dont see the majority of ppl complaining because they're NOT aimed at u and me and ferrari & lamborghini could care less what we think cause we're not their target audience. get over yourself, there ARE cards for you in the $100+ $300, so what are u worried about?timmiser - Tuesday, January 24, 2006 - link
While I agree with what you are saying, we are already on our 3rd generation of $500 high end graphic cards. If memory serves, it was the Nvidia 6800 that broke the $500 barrier for a single card solution.I'm just happy it seems to have leveled off at $500.

Actually GPU's in general scale very well with price/performance and this is no exception. Twice as fast as a 850 XT which you can get for $275 should cost twice as much or $550 which it does. If you want to complain about prices look at CPUs, high end memory and raptors/SCSI which higher line items offer small benefits for huge price premiums.fishbits - Tuesday, January 24, 2006 - link
Geez, talk about missing the point. News flash: Bleeding edge computer gear costs a lot. $500 is an excellent price for the best card out. Would I rather have it for $12? Yes. Can I afford/justify a $500 gfx card? No, but more power to those who can, and give revenue to ATI/Nvidia so that they can continue to make better cards that relatively quickly fall within my reach. I can't afford a $400 9800 pro either... whoops! They don't cost that much now, do they?Short-sighted again. Look at the launch of Unreal games for instance. Their code is always awesome on the performance side, but can take advantage of more power than most have available at release time. You can tell them their code is shoddy, good luck with that. In reality it's great code that works now, and your gaming enjoyment is extended as you upgrade over time and can access better graphics without having to buy a new game. Open up your mind, quit hating and realize that these companies are giving us value. You can't afford it now, neither can I, but quit your crying and applaud Nv/ATI for giving us constantly more powerful cards.

Agreed, I'm not sure how anyone constitutes $500 for ONE component a good price. I'll pay no more than 300-350 for a vid card.bamacre - Tuesday, January 24, 2006 - link

I like new line graph color and interface, but i like bar graph so much more. Never a big fan over SLI or Crossfire on the graph, makes its a distracting, especially it only represent a small group. Wonder if crossfire and sli can have their own graph by themselves or maybe their own color. =)DerekWilson - Tuesday, January 24, 2006 - link
it could be possible for us to look at multigpu solutions serpeately, but it is quite relevant to compare single card performance to multigpu performance -- especially when trying to analyze performance.Live - Tuesday, January 24, 2006 - link
Good reading! Good to see ATI getting back in the game. Now lets see some price competition for a change.I don’t understand what CrossFire XTX means. I thought there was no XTX crossfire card? Since the Crossfire and XT have the same clocks it shouldn’t matter if the other card is a XTX. By looking at the graphs it would seem I was wrong but how can this be? This would indicate that the XTX has more going for it then just the clocks but that is not so, right?
Bha I'm confused :)

My understanding is that Crossfire is async, so both cards run at their maximum speed. The XTX card runs at 650/1.55, while the Crossfire Edition card runs at 625/1.45. You're right, there is no Crossfire Edition XTX card.
