PowerVR graphics technology is based on a concept called Tile Based Deferred Rendering (TBDR). In contrast to Immediate Mode Rendering (IMR) used by most graphics engines in the PC and games console worlds, TBDR focuses on minimising the processing required to render an image as early in the processing of a scene as possible, so that only the pixels that actually will be seen by the end user consume processing resources. This approach minimizes memory and power while improving processing throughput but it is more complex. Imagination Technologies has refined this challenging technology to the point where it dominates the mobile markets for 3D graphics rendering, backed up by an extensive patent portfolio.

The latest generation of this advanced architecture is the PowerVR Series6 family of graphics IP cores. Based on a scalable number of compute clusters, the PowerVR Series6 ‘Rogue’ architecture is designed to target the requirements of a growing range of demanding markets from mobile to the highest performance embedded graphics including smartphones, tablets, PC, console, automotive and TV. Using these arrays of programmable computing elements, PowerVR Series6 cores deliver class-leading graphics and GPU Compute efficiency while minimising power and bandwidth demands.
