The Tech Report was paying close attention during nVIDIA’s 4th quarter conference call, and caught mention of physics processing coming to certain nVIDIA cards.  After further discussions, it turns out that any card with CUDA (Compute Unified Device Architecture) will be able to start doing physics processing with a tweak to the software, no hardware changes necessary.  The good news is that all 8800 series cards use CUDA, meaning that any and all of those cards are capable of physics processing using their GPUs.  Now we have two questions remaining, when will we see it, and what kind of performance hit will we see when physics processing is enabled.

“During Nvidia’s fourth-quarter financial results conference call, Nvidia shed a little more light on its acquisition of Ageia and what it plans to do with the firm’s PhysX technology. Nvidia CEO Jen-Hsun Huang made no announcements regarding the deal until asked in the question-and-answer session, but he was happy to divulge a decent number of details.”
