What Intel's Breakup Would Mean for TSMC and Broadcom

In This Article:

Intel (NASDAQ: INTC) might be split up and sold to Taiwan Semiconductor Manufacturing (NYSE: TSM), also known as TSMC, and Broadcom (NASDAQ: AVGO), according to the latest rumors. The chipmakers haven't responded to those reports, but such a deal could shake up the semiconductor industry.

The most recent report from The Wall Street Journal claims Intel held "informal" talks to sell its foundry business to TSMC and its chip design business to Broadcom. Both rumored deals would likely face intense regulatory scrutiny, but we should discuss how Intel got here -- and what its breakup and sale might mean for TSMC and Broadcom.

How did Intel fall this far?

Intel is still the world's largest designer and manufacturer of x86 CPUs for PCs and servers. However, it missed the leap to mobile chips and ceded that growing market to Arm's power-efficient chip designs, and its foundries fell behind TSMC and Samsung in the "process race" to manufacture smaller and denser chips.

As Intel struggled with shortages and delays, its smaller x86 competitor, AMD, pulled ahead with a stable supply of cheaper and more power-efficient chips by outsourcing its production to TSMC. Instead of catching up to TSMC, Intel repeatedly shifted its short-term strategies under three CEOs over the past decade.

Under Pat Gelsinger, who served as Intel's CEO from 2021 to 2024, the chipmaker tried to expand and upgrade its foundries to catch up to TSMC and Samsung. But those capital-intensive efforts coincided with the broader slowdown of the PC market, and it struggled to ramp up its production of its Meteor Lake CPUs to fend off AMD. Its CPUs also became less relevant than Nvidia's GPUs as companies scrambled to upgrade their data centers to handle the latest artificial intelligence (AI) applications.

Intel won't go bankrupt anytime soon, but it's clearly being left behind in the semiconductor race. That's why it isn't too surprising that the chipmaker, which still lacks a permanent CEO, might be mulling a sale to TSMC and Broadcom.

What would that deal mean for TSMC?

TSMC is already the world's largest and most technologically advanced contract chipmaker. The top fabless chipmakers -- including Nvidia, AMD, and Apple -- all outsource the production of their smallest chips to TSMC.

TSMC controls 64.9% of the global foundry market, according to TrendForce. Samsung ranks a distant second at 9.3%, while Intel only holds 1% of the market. Therefore, buying Intel's foundries would only slightly increase TSMC's market share, but it would snub Intel's fledgling efforts to pull away some of its fabless clients.
