A pair of new reports suggest the second-generation iPad will feature a 2048×1536 display, as well as a multi-core GPU and multi-core ARM Cortex-A9 processor. Mac Rumors reports that two iPad “x2” graphics have been discovered in the latest version of iBooks, including a bookmark icon found in August, and a new wood tile graphic, both of which are twice the resolution of their predecessors, suggesting an overall resolution of 2048×1536. The article notes that a higher-resolution display would require a more powerful graphics unit to drive it, partially explaining the appearance of a driver for the POWERVR SGX543 GPU in the first iOS 4.3 beta.
Citing a source familiar with Apple’s graphics strategy, AppleInsider reports that the company will be using a dual-core variant of the SGX543, known as the SGX543MP2, which will offer roughly four times the performance of the A4’s SGX535. The report also claims that the new GPU will be paired with a multi-core ARM Cortex-A9 for general computing processing, and notes that many of the iPad’s 2011 tablet rivals will be using a similar multi-core, A9-based processor when they hit the market later this year. Finally, the report suggests that the new graphics prowess could enable Apple to offer HDMI output on the iPad and iPhone, and could potentially lead to 1080p output for a next-generation Apple TV.
