Though ATI was singing quite a different tune at this year's Computex, it seems that many were right in assuming ATI's answer to PhysX won't be here for quite some time. At Computex, ATI demonstrated their way of doing native physics processing by coupling multiple Radeon cards together. The idea sounds neat and supposedly is already supported in the RD600 based cards, but it won't be in the hands of the consumer for at least another 9 to 12 months. Many things can change over the course of the next year, and hopefully this delay in release will mean a better product in the long run. After the initial flop that was Crossfire, ATI doesn't want to disappoint customers again.
This delay may also prove beneficial to Ageia, who have been finding it difficult to get vendor support for PhysX. The concept of native physics processing hasn't taken off with many game developers, but good physics are becoming increasingly more important. 2007 could be the year of the physics processor.
