Appleís cut-price iPad 2, which it continues to sell alongside its new iPad, has been given a boost with a shift to a new 32nm A5 processor from the original 45nm iteration. Although using fundamentally the same architecture, the die-shrunk version has been shown by Anandtech to draw less power offering significant improvements in battery life. The latest iPad 2ís carrying the updated dual-core processor are designated by the model number ëiPad 2,4í and utilize Samsungís 32nm high-k + metal gate LP transistors, which helps to explain the performance differential.
