UK based Imagination Technologies, the popular developers of mobile graphics products have recently unveiled their new PowerVR SGX545 mobile GPU.
Apple, which holds a 9.5% stake in the company is likely to incorporate these chips in the upcoming iPhone model.
At present, the graphics display on the iPhone has been bettered by more up-to-date technologies on devices such as Motorola Droid and Nexus One. The PowerVR SGX545 enables superior display of 2D and 3D images along with extensive support for OpenGL 3.2 and OpenCL 1.0.
Here is a complete list of features offered on PowerVR SGX545 mobile GPU:
- DirectX10.1 API support
- Enhanced support for DirectX10 Geometry Shaders
- DirectX10 Data assembler support (Vertex, primitive and instance ID generation)
- Render target resource array support
- Full arbitrary non power of two texture support
- Full filtering support for F16 texture types
- Support for all DirectX10 mandated texture formats
- Sampling from unresolved MSAA surfaces
- Support for Gamma on output pixels
- Order dependent coverage based AA (anti-aliased lines)
- Enhanced line rasterisation
In addition to this, OpenCL 1.0 is expected to offer additional features like 32-bit integer support, 64-bit integer emulation and 3D texture support. With the ability to deliver 40 million polygons per second at 200 MHz, the mobile GPU is said to offer high quality rendering of 3D content. For a perspective, Sony claims a theoretical performance of 33 million polygons per second at 333 MHz for its PSP.
Apple incorporating this mobile GPU in iPhone 4G is still a speculation. But considering the likelihood, we could expect the iPhone to not just compete against the smartphones in the future, but also be a viable threat to the likes of PSP. What do you think?
