New PowerVR SGX545 Mobile GPU Headed to the iPhone?

Imagination Technologies has announced the POWERVR SGX545 graphics IP core, a high end addition to the SGX series used in the iPhone.

The POWERVR SGX545 is the first and only DirectX10.1 capable embedded graphics IP core available for immediate licensing. SGX545 will also deliver OpenGL ES 2.x and OpenGL 3.2 to deliver class leading 3D graphics performance, and will also support OpenCL 1.0 full profile capability which will enable mobile and embedded applications to take maximum advantage of the capabilities offered by these GPU APIs for both 3D graphics and general purpose applications.

POWERVR SGX545 delivers real-world performance of 40 million polygons/sec and 1 Gpixels/sec fillrate at 200MHz,* and is capable of driving HD screens with ultra smooth high frame rate 3D graphics content.


New features in POWERVR SGX545 include:
* 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

SGX545 was also designed to deliver full profile OpenCL 1.0 capabilities, with advanced features including:
* Support of round-to-nearest for floating-point math
* Full 32-bit integer support (includes add, multiply and divide)
* 64-bit integer emulation
* 3D texture support
* Support for the maximum 2D and 3D image sizes specified in the full profile.

Its thought that the SGX545 will be used in the next generation iPhone as an upgrade to the SGX535 used in the current iPhone 3GS. Notably Apple owns about 9.5% of Imagination Technologies.
