Unless Intel Wins Apple, Foundry Is a Waste of Time

Touted as a great savior for Intel's business, the foundry business isn't anywhere near the panacea that some believe it to be.

May 11, 2014 at 4:00PM

Intel (NASDAQ:INTC) has been pretty loudly telegraphing its intentions to become a major, high-end semiconductor foundry player. Its highest-profile win to date has been FPGA vendor Altera, and it is presumed that the company is working to bring aboard more customers interested in the leading edge. Some investors believe that Intel's future is as a semiconductor foundry, but if you really dig deep into the numbers, there's just not enough business there to make it worth Intel's while.

How big is the market for a leading-edge foundry?
In the foundry landscape, the latest technology node is known as the 28-nanometer node. (This is actually a bit misleading as there are several flavors of 28-nanometer out there -- 28 poly silicon for cheaper, lower-performing devices, and 28 high-K/metal gate for higher-performance devices.) To get a sense of the market opportunity for a leading-edge foundry, it's worth looking at just how big the market for a 28-nanometer foundry is today.

Taiwan Semiconductor (NYSE:TSM), the world's leading semiconductor foundry, saw its 28-nanometer node begin to ramp into volume by late 2011 to early 2012. Here's a look at 28-nanometer revenues at TSMC by quarter:

28-nanometer revenue (in millions USD)











Percentage of net revenue











In 2013, TSMC did roughly $6 billion in leading edge 28-nanometer revenue. If we assume that TSMC's share of 28-nanometer was about 84% in 2013 (per TSMC's own statements), this implies a leading-edge total addressable foundry market of about $7 billion. Note, however, that the second largest 28-nanometer player in 2013, Samsung, saw most of its business come from Apple, as it builds Apple's A-series processors, and the third largest player, Global Foundries, was likely mostly revenue from Intel rival Advanced Micro Devices (NASDAQ:AMD).

This business isn't worth it without Apple
Intel is unlikely to build chips for direct PC-chip competitor AMD, nor is it likely to build chips for Qualcomm (NASDAQ:QCOM), the world's leading smartphone chip vendor and by far TSMC's largest leading-edge customer, as that would eliminate Intel's biggest competitive advantage for its own processors. So we're talking about a $7 billion-per-year total market, most of which is silicon from Qualcomm, AMD, NVIDIA (NASDAQ:NVDA), and Apple.

Since AMD, NVIDIA, and Qualcomm would be extremely poor strategic choices for Intel, the only real "large" customer that Intel will be able to win at the leading edge would be Apple. Even then, if we assume that Samsung gets between $10 and $15 per chip from Apple for its very leading edge, this wouldn't amount to more than $1 billion of leading-edge business per year. (Remember, not all of Apple's phones are the latest one in any given year, so the portion that is leading edge is much lower than the total Apple business.) This just isn't all that much and would be more of a strategic win (i.e., to keep that revenue out of the foundry landscape) than it would be a way to meaningfully increase revenues.

Foolish bottom line
The leading-edge foundry business is worth about $7 billion a year, which just isn't all that much to a company like Intel, which does $33 billion a year in PC chips and an additional $11 billion to $12 billion a year from server processors. The foundry business works for pure-play folks like TSMC because foundries don't need to spend a dime on actual chip development. Intel, on the other hand, is investing nearly $3 billion a year in mobile processor R&D, so taking competitor business (from Qualcomm and NVIDIA, for example) doesn't make sense, and even something like an Apple deal, which -- if Apple went long-term exclusive with Intel -- would be worth about $1.5 billion to $2 billion, with even less than that at the leading edge.

Intel is better off developing competitive mobile products and capturing much more value that way.

Apple's foundry business is nice, but this Apple supplier could make you rich
If you thought the iPod, the iPhone, and the iPad were amazing, just wait until you see this. One hundred of Apple's top engineers are busy building one in a secret lab. And an ABI Research report predicts 485 million of them could be sold over the next decade. But you can invest in it right now, for just a fraction of the price of Apple stock.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.
