How a Decision by Apple 15 Years Ago Hurts Intel Now

Last month Intel’s stock lost $50 billion in valuation — while the valuation for Taiwan-based TSMC jumped by over 50%.

The former chief of staff to Intel CEO Andrew Grove (and later general manager of Intel China) explains why this moment was 15 years in the making: Learning curve theory says that the cost of manufacturing a product declines as the volume increases. Manufacturing chips for the whole computer industry gave Intel huge advantages of scale over any other semiconductor manufacturer and resulted in the company becoming the world’s largest chip manufacturer with enviable profit margins.

Chaos theory says that a small change in one state of a system can cause a large change in a later stage. In Intel’s case, this was not getting selected by Apple for its iPhones. Each successive era of computing was 10x the size of the previous era, so while Intel produced hundreds of millions of microprocessors per year, the mobile phone industry sells billions of units per year. Apple’s decision in 2005 to use the ARM architecture instead of Intel’s gave Taiwan-based TSMC, the foundry chosen to manufacture the processor chips for the iPhone, the learning curve advantage which over time enabled it to pull ahead of Intel in manufacturing process technology.

Intel’s integrated model, its competitive advantage for decades, became its vulnerability. TSMC and ARM created a tectonic shift in the semiconductor industry by enabling a large number of “fabless” chip companies such as Apple, AMD, Nvidia and Qualcomm, to name a few. These fabless companies began to out-design Intel in the mobile phone industry and accelerated TSMC’s lead over Intel in high volume manufacturing of the most advanced chips. Samsung, which also operates a foundry business, has been another beneficiary of this trend.
