Triple Play physics just around the corner

More information about ATI's long-awaited physics processing is finally trickling into light. ATI has named its GPU accelerated physics processing Asymmetric Physics Processing.

Hardware requirements for Asymmetric Physics Processing include two AMD ATI Radeon based graphics cards and a compatible CrossFire motherboard.  One Radeon may be used as a GPU with an additional Radeon acting as a physics processor.  The requirement for three Radeons to complete physics processing is only a requirement of Triple Play operation.

ATI’s Triple Play physics processing is also supported with two ATI Radeon graphics cards operating in CrossFire with an equal or lesser performing third card dedicated to physics processing. 

Chile Hardware has the full presentation for Asymmetric Physics Processing in English and Spanish.

Asymmetric Physics Processing requires two AMD ATI Radeon graphics cards for baseline processing, the two graphics cards do not need a direct physical link like CrossFire. AMD is also touting the ability to mix and match different ATI Radeon graphics cards to have greater flexibility for users that upgrade their older graphics cards.

At this time it seems AMD chipsets are the only supported platform for Asymmetric physics processing. Supported chipsets include the AMD 580X, ATI CrossFire Xpress 3200 (for Intel) and the upcoming RD790. It is unknown if the CrossFire capable Intel 975X and P965 chipsets will be supported.

Yeah it's a little rediculous isn't it?

I personally think that the PhysX approach is more elegant anyway. Not to mention that a $200 PhysX card is a lot cheaper than a 2nd or 3rd high end video card.

I've also heard that some physics functions can't be run on video cards because everything has to be converted to Direct X 9 and back again through software to make it work.

The third card could be old X1300 you bought or picked up cheap when someone upgraded their system. 6 bays. Now us Techie fellas know there are plenty of ATI single slot cards out there. They needed space to put the word Physics and Rendering. There is always a product griefer in every discussion.

A x1600 class graphicscard has more that enough calculating power to start with.. besides that.. buying a x1900 class card will put your electricity bill through the roof

needing a 500 watt psu is rediculous.

what utter shit amd/ati come up with as "solutions".

I couldnt imagine more than 1% of gamers really want to get a crossfire system and spend 500+ minimum on video cards.

With regard to physics/parallel-number-crunching on a GPU, I refer you to Anandtech's article on the 8800GPU. Far more factual and informative than all the marketing hype and technical misunderstanding circulating at the moment.

http://www.anandtech.com/video/showdoc.aspx?i=2870

BTW, physics computations have nothing to do with Dx9c. The misunderstanding seems to come from some warble that Microsoft has made about a Physics API being incorporated into future updates to DX10. However, both Havok and Ageia market third-party physics software Development toolkits for both WinXP and Vista, with Havok FX being targeted for computation on GPUs (not to be confused with Ageia PhysX hardware -- now pretty well a dead-duck, with the arrival of multicore CPU and massively-parallel-processing GPUs)

I remember reading somewhere that dx10 hardware is due to their design more easy to program than dx9. This might be the reason for the confusion where people think that the dx10 api includes physics capability at this moment. A simple hardware vs software confusio.

If they implement a new driver for the physics GPU, so that they don't necessarily have to rely on using the directx API then it shouldn't really be a problem. That is until there is a directPhysx implementation.

According to pricewatch.com, a SAPPHIRE Radeon X1900GT (RV570) cost around 161 USD.

Not with AMD's CTM ("Close To Metal").
