Approximate size comparison between Apple S1 and A6

In contrast to the chips from the Apple Ax series used in the iPhone and iPad , the Apple S1 is not a system on a chip , but a system in a package . This means that the S1 is not part of a computer , but rather an independent computer system in a package. Many components are integrated in the S1 that are usually connected as peripherals in a SoC, such as the flash memory and the WLAN module. According to Apple, the S1 is covered with a resin to protect the components. Official pictures show the S1 with a metallic heat spreader . The processor is said to be manufactured in Samsung's 28 nm process, which is similar to the process already used in the Apple A5 chip . It gets by with a voltage of 0.9  volts . For the production should monthly 3,000 to 4,000 twelve- inch - wafers have been ordered. The main memory should have a size of 512  MB , while the flash memory is available with a capacity of 8 GB. Chipworks suggested that the WLAN module in the S1 is a Broadcom BCM4334 dual-band chip. There are Wi-Fi b / g / n in the 2.4 GHz frequency band with a data rate of up to 54  Mbit / s, Bluetooth 4.0 and FM radio reception support.

The online magazine 9to5mac cited unknown sources that ranked the performance of the S1 slightly below the S5L8942 in the 5th generation iPod touch .
