AMDZone has posted up some tests of the Ageia PhysX RealityMark. It is based off of Cell Factor, and compares software mode versus hardware mode.
While we applaud that they are attempting to show off the strengths of the hardware, a performance difference this vast with a dual core CPU even this strong is more alarming on their point for bias than something that supports the strengths of the PhysX hardware. In other words, more marketing fluff than anything substantial. We hope Ageia spends more time supporting game developers and finding better uses of their PhysX processors than time spent on a benchmark like this, which is not likely to generate support in the hardware community.
