Samsung Electronics announced the latest in its popular, ARM11 series of application processors, the S5P6440.
Designed using Samsung’s advanced 45nm low power CMOS process technology, the S5P6440 offers a low power, high performance, and cost effective solution for consumer electronic (CE) products such as personal navigation devices (PND).

Samsung's S5P6440 is based on an ARM1176 CPU core which runs at either 533 MHz or 667MHz clock speed. The CPU core and all on-chip hardware accelerators and peripheral interfaces are connected through a 64-bit AXI bus running at 166MHz, allowing ample input/output bandwidth for handling the multiprocessing requirements in real-life applications.
The Samsung ARM11 S5P6440 features 2D graphics acceleration hardware that is compliant with the OpenVG application programming interface (API) standard. The OpenVG API standard enables advanced graphics functions such as alpha blending for transparency effects, anti-aliasing for sharper graphics, and vector graphics support for scaling without loss of image quality.

By the way the new iPhone 3GS is not running on an ARM11 it is using the more powerful ARM Cortex-A8 processor.
