Giving a peak at the details A4, Apple’s first in-house microprocessor which powers the newly-released iPad, Bright Side of News has reported that the system-on-a-chip includes an ARM Cortex-A9-based CPU along with an ARM Mali 50-series GPU.

As per Bright Side of News, Apple’s new A4 custom silicon chip is largely based on intellectual property from ARM reference designs; with its Cortex-A9 MPCore being similar to the processor in the Qualcomm Snapdragon and the nVidia Tegra. The chip also features a memory controller all on one die.

The report elaborated: “The A stands obviously for Apple, and the difference between the Samsung processor inside the iPhone 3Gs and A4 is the clockspeed and the core type. A4 runs at 1GHz while the chip on iPhone 3GS works clocked to 0,6GHz. This is one of main reasons why iPad can deliver a lively interface compared to stale iPhone one.”

Going by the iPad’s hands-on impressions from AppleInsider, the custom silicon A4 is a next-generation chip that is even faster than the exceedingly fast iPhone 3GS.

With Apple noting that the custom-built A4 chip is extremely power-efficient, and provides the iPad ten hours of battery life when in use, and more than one month of standby time; it is being assumed that the chip might also be a part of the new iPhone model which will likely be introduced this year.
