Naked Sky Entertainment developed RoboHordes, the first Unreal Engine 3 game to show off multi-threaded physics, using AGEIA's NovodeX Physics SDK

Let's get physical. What exactly is a PPU?

Manju Hegde: A Physics Processing Unit (PPU) is a completely new hardware category that bridges the gap between static virtual worlds and pervasive physical reality. This new hardware category represents the next milestone in the evolution of game acceleration, following in the footsteps of the CPU and GPU. The PPU works alongside these processors, completing the triangle of gameplay, 3D imagery and physics-based interaction.

AGEIA's PhysXchip is the world's first dedicated PPU. With AGEIA's groundbreaking new technology, developers can now create scenes using the same laws of physics that govern the physical universe, enabling players to interact with any object in any scene at any time, providing pervasive interactive reality. In concert with the CPU and GPU, the PhysX chip will allow game developers to create characters, backgrounds and effects that rival those of Hollywood movies, but with interactivity.
