Apple A6X

The new A6X chip inside the iPad 4 (yes, I'm calling it that) is a new dual-core CPU combined with quad-core graphics. According to Apple, it is up to twice as fast as the previous-generation A5X chip.

Given the significant boosts in clock frequency—150 percent for the CPU cores, and 200 percent for the GPU cores—you may be wondering how Apple can still promise a 10-hour battery life. After all, the iPad still has the exact same 42.5Whr battery, but the processor is twice as powerful. The power savings come from the same place as we saw in the iPhone—Apple moved from a 45nm process to a more power-efficient 32nm process. Instead of keeping performance the same and decreasing the iPad's thickness and weight, Apple instead chose to double its performance without sacrificing all-day battery life.

Ilmeisesti A6X:ssä on 2 cpu ydintä. Kellotaajuutta on lisätty ja arkkitehtuuria parannettu, lisäksi valmistusteknologiaa on myös parannettu.
