Apple shipped nearly 50 million products in 2010 based on its A4 processor, including the iPad, iPhone and Apple TV, according to research firm IHS iSuppli.
Analysts said the A5 chip may be based on ARM's Cortex-A9 design, which is used in Nvidia's Tegra 2 chip. The next logical step for Apple would be to make a quad-core version, which would deliver even more processing power.
At the Mobile World Congress in Barcelona last month, Nvidia announced a quad-core chip code-named Kal-El, which it claims is twice as fast for Web browsing as the dual-core Tegra 2, which is used in Motorola's Xoom tablet. Qualcomm also announced a quad-core Snapdragon chip for mobile devices at the show.
