Apple?s iPhone 5s features some advanced components that represent pioneering achievements for the smartphone market while maintaining a nearly identical cost compared to the iPhone 5. The low-end version of the iPhone 5s with 16 GB of NAND flash memory has a bill of materials (BOM) of USD 191, according to the preliminary results of a physical dissection of the device conducted by the Teardown Analysis Service at IHS. When the USD 8 manufacturing expense is added in, the cost rises to USD 199. The compares to a USD 197 total cost for the original iPhone 5, based on the completed IHS teardown analysis from one year ago.
Although other smartphones have included 64-bit graphics processors, the 5s is the first model with a 64-bit applications processor. Report authors believe that the move to the 64-bit apps processor is largely driven by the need for greater computational power to ensure that the smartphone?s fingerprint sensor works quickly and seamlessly. The processor also boosts the performance of the iPhone 5s?s camera, allowing 120 frame-per-second (FPS) video and 10 FPS photo capture. This design change is forecast to set the stage for 64-bit processors to be used in upcoming Apple products, including new models of the iPad, the Apple TV and even MacBook Air PCs.
The 64-bit processor is part of the Apple-designed A7 apps processor, based on a core from ARM. The new 64-bit processor core is called ?Cyclone?, as opposed to the 32-bit version used in the iPhone 5 and 5c, known as ?Swift?. Despite the well-publicized feud between the companies, Samsung is the manufacturer of Apple?s A7. This likely is because Samsung has a license to ARM's 64-bit core. The A7 used in the iPhone 5s costs USD 19, significantly higher than the A6 used in the original iPhone 5 and 5c, which currently carries a cost of USD 13.
In addition, Apple has updated the memory of iPhone 5s to LPDDR3, marking the first time that the IHS Teardown Analysis Service has identified this advanced type of DRAM in an electronic product. Apple probably used this high-speed memory?as opposed to the LPDDR2 employed in the original iPhone 5 and 5c?to support the fast processing speeds of the A7. The 1 GB of LPDDR3 costs USD 11, up from USD 9.50 for the same quantity of LPDDR2 in the 5c.
The report further indicates that the addition of the fingerprint scanner also represents an increased hardware cost for the 5s. The user-interface segment of the 5s, which includes the fingerprint scanner, costs USD 15. This compared to just USD 8 for the user interface for the 5c, which has no fingerprint scanner.
The combined BOM and manufacturing cost for the midrange iPhone 5s with 32 GB of NAND flash is estimated at USD 208. The 64-GB model?s cost totals USD 218.
