NOTE: Questiоns 36 thrоugh 40 аre bаsed оn this аrticle: Intel’s Recovery Will Demand More Than Just Engineering Skills How hard will the new Intel chief executive’s job be? The company’s top rival just gave some important clues. Pat Gelsinger doesn’t start at the company until mid-February, but Intel’s fourth-quarter results Thursday afternoon will likely give a strong sign of at least his initial path. Intel has promised to use the occasion to update investors about its continuing manufacturing problems. The company has also said it would indicate whether it intends to stick with its long-running practice of being the sole manufacturer of the chips it designs, or whether it will begin outsourcing the production of some future designs, very likely to Taiwan Semiconductor Manufacturing, TSM 2.69% or TSMC. Mr. Gelsinger’s long tenure as an Intel engineer strongly suggests the chip maker isn’t ready to throw in the towel just yet on manufacturing. But competing with an ascendant TSMC will be a daunting task. TSMC reported Thursday that revenue for 2020 surged 31%—its best growth in more than a decade—to a record $45.5 billion. And demand is so hot for the company’s manufacturing services that TSMC also plans to pour a record amount into capital expenditures for the coming year to expand its capacity. The chip maker expects to spend between $25 billion and $28 billion for 2021—double the annual capex bill that Intel has averaged over the past five years. Intel is still a much bigger company, with 2020 revenue projected to land around $75.3 billion—up 5% from the previous year. But the recent lift from booming PC sales and data-center demand won’t solve the company’s manufacturing woes. Wall Street currently expects Intel’s revenue this year to fall 7%—which would be the company’s worst decline in more than a decade. TSMC is projected to boost revenue 20% to about $54.4 billion for 2021, according to FactSet. Intel says it has made strong progress on its 7-nanometer manufacturing process, which has been the source of recent trouble. But TSMC is now making more advanced chips en masse at 5 nanometers. The company is already developing its 3-nanometer process, which it said Thursday would be producing chips in volume by the second half of 2022. That means that even if Mr. Gelsinger is successful at getting Intel’s manufacturing process back on track, the company will still be badly lagging. Stacy Rasgon of Bernstein says Intel’s disadvantage to TSMC is “likely set in stone” for at least the next three years. So while this week’s results and update will be delivered by Chief Executive Bob Swan, who is staying until Feb. 15, it will fall to Mr. Gelsinger to convince Intel’s employees, customers and investors that the company’s future is worth the wait. It is also possible he will be the one to sell those same stakeholders on even more radical options, such as a joint venture with TSMC. Some analysts have even recommended that Intel go full “fabless”—which would involve getting out of manufacturing altogether. The latter is unlikely; finding a buyer for Intel’s domestic facilities that would be palatable to U.S. regulators would be a very high hurdle. But even a more limited outsourcing strategy will have its costs, given that Intel will need to both pay a manufacturing partner and fund its own chip fabrication facilities. Mr. Gelsinger, in other words, has no easy options. His appointment has been roundly cheered on Wall Street, with at least six brokers upgrading the stock since then. The running assumption is that a leader with technical chops is better suited to addressing Intel’s problems. The irony is that convincing Intel’s many stakeholders of whatever path the company takes will be more of a sales job.
