ATI says they have the best physics processing in the world stating that their branch execution unit eliminates much overhead as compared to team Green. Also ATI says they are going to be simply faster than an Ageia PhysX card even with using a X1600 XT and that a X1900 XT should deliver 9 X the performance of an Ageia PhysX card. ATI does not see their physics technology as an offload for the CPU but rather processes a new category of features know as “effects physics.”
Whether or not a standard Radeon will outshine a dedicated physics card such as PhysX remains to be seen, but it's a bold claim either way. In the same tone, they claim that CrossFire will start to outshine and overtake SLI as soon as early next year. Can ATI deliver?
