The P1 features 128 MB of GDDR3 memory, connected through a 128-bit interface, and supports 22 billion instructions as well as 533,000 complex collisions per second. The PhysX chip promises additional dynamic motion and interaction, which translates into more realism in effects such as explosions, water splashes and wind-driven movements.
