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.

Almost $900 CDN for the XTX and it only has a 1 year warranty?Main reason I would never buy an expensive ATi card is that right there.

The people who buy a card this expensive the first day it comes out won't keep it for a whole year, so the warranty doesn't matter. In 6 months another card will be out that makes this one look slow and they'll be spending even more money.DerekWilson - Tuesday, January 24, 2006 - link
Due to popular demand, we have added more percent increase performance comparison graphs to the performance breakdown that shows the performance relatoinships at lower resolutions.Let us know if there is anything else you'd like to see. Thanks!

The performance breakdown looks very good now! I would go so far as to say that this should be standard in future reviews.piroroadkill - Tuesday, January 24, 2006 - link
Using a lossy image format (JPEG) for image quality comparison screenshots seems kind of... pointless.But I guess you have to worry about bandwidth.

Thanks for the input all. Just to let you know we are dealing with some problems regarding our power numbers, but they should be up shortly. Thanks for being patient.Josh Venning - Tuesday, January 24, 2006 - link
One more thing.. We also caught a mistype on the graphs that we are in the process of correcting. The two crossfire systems we tested are the X1900 XTX Crossfire and the X1800 XT Crossfire. (we miss-labeled the latter "X1900 XT Crossfire") Sorry for any confusion this may have caused.smitty3268 - Tuesday, January 24, 2006 - link
Ah... That makes much more sense now. I was wondering why the XTX crossfire was doing so much better than the XT crossfire when the specs were so similar.SpaceRanger - Tuesday, January 24, 2006 - link
Problems with the publishing of them, or problems in the sense that it requires a direct link into a nuclear reactor to power properly??

our local nuclear plant ran us an extention cord just for this event :-)
