A5X Chip Apple announced a new microprocessor for the new iPad, codenamed A5X. It is a quad-core chip, which means four chips on a single processor. Apple said that the new chip can deliver four times the performance of Nvidia's ( NVDA) Tegra 3. It's unknown at this point whether the chip is a dual-core CPU and a quad-core CPU or quad-core all around. Apple said the A5X is twice as fast as the processor for the iPad. This will allow games and videos to be played longer, as the battery life will not suffer.
