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.
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
ATI CrossFire Xpress 3200 (for Intel)
and the upcoming
. It is unknown if the CrossFire capable Intel 975X and P965 chipsets will be supported.

It's all about the flops and memory bandwidth. GPU's have it, CPUs don't. The higher you set a baseline (let's say a x1600 with 86.4gflops and 22.4gb/s) the prettier physics is going to look. Look at the flop count and memory bandwidth even for something like Core2, it's not even close. I don't know the flop count of the physX (noone does) but I reckon the x1650xt surpasses it in computational power. Not only could this be awesome if there is a good API for physics, but it shows how the computational power ATi has been putting in even their low-end products can be put to good use. First folding, then physics, then perhaps GPU-accelerated decoding (that we were promised long ago) and who knows what else.
If you doubt the efficiency of multi-gpus in a system over multi-cores, just google 'Peakstream', I reckon it may change your mind.

Oh but I have no doubt whatsoever! I just thought i'd post simply to see if there was an english version of chilehardware.
