Faster processor and graphics

There's little doubt that the next iPad will have a more powerful next-generation processor with improved graphical capabilities. Despite the power boost, that chip, which most people expect to be called the A6 (the iPad 2 and iPhone 4S have the A5), is supposed to be more energy-efficient, so it isn't expected to be a battery killer.

Whether the A6 will be a quad-core chip remains unclear, but we should get all the details in March, with Apple boasting of, say, "4x faster graphics than iPad 2."
