iPad 2 and iPhone 5 to use new A4 chip with dual core SGX543

According to a news leaked on appleinsider.com , Apple will use on its next generation iPad 2 and iPhone 5 an advanced version of the Cortex-A9 processor packing and ultrafast dual core SGX543 graphics allowing the next generation to support the 1080p full HD and HDMI output :

"Later this year, Apple will introduce its second generation iPad, the iPad 2 reportedly with double the resolution and four times the pixels to process. That type of display upgrade would necessitate a big boost in graphics and video processing power. 

Apple's next custom System on a Chip is expected to jump from the SGX535 (which has been used since the iPhone 3GS) to the new SGX543 graphics and video core, which is said to offer around twice the processing power at the same clock speed. The new graphics core also supports OpenCL, used to offload general purpose computing tasks on the GPU for fast execution."
