Engineers at marketing research firm IHS Markit cracked open the base version iPhone X, which Apple is selling at $999, this week. After preliminary physical dissection, the firm estimated that the iPhone X carries a bill of materials of $370. From their findings: With a starting price of $999, the iPhone X is $50 more than the previous most expensive iPhone, the 8 Plus 256 GB. As another point of comparison, Samsung's Galaxy S8 with 64 GB of NAND memory has a BOM of $302 and retails at around $720. "Typically, Apple utilizes a staggered pricing strategy between various models to give consumers a tradeoff between larger and smaller displays and standard and high-density storage," said Wayne Lam, principal analyst for mobile devices and networks at IHS Markit. "With the iPhone X, however, Apple appears to have set an aspirational starting price that suggests its flagship is intended for an even more premium class of smartphones." The teardown of the iPhone X revealed that its IR camera is supplied by Sony/Foxconn while the silicon is provided by ST Microelectronics. The flood illuminator is an IR emitter from Texas Instruments that's assembled on top of an application-specific integrated circuit (ASIC) and single-photon avalanche diode (SPAD) detector from ST Microelectronics. Finisar and Philips manufacture the dot projector. IHS Markit puts the rollup BOM cost for the TrueDepth sensor cluster at $16.70.
