A.I. has added urgency to the U.S. national laboratories that have been sites of cutting-edge scientific research, leading to deals with tech giants like Nvidia to speed up.

Lip-Bu Tan, who was appointed chief executive of Intel in March, is also a longtime venture capitalist. His dual roles have caused some consternation.

A.I. companies are buying up memory chips, causing the prices of those components — which are also used in laptops and smartphones — to soar.

A technical partnership embraces SambaNova Systems, which Intel’s chief, Lip-Bu Tan, helps lead as an investor and chairman.

The chip maker reported a 7 percent rise to $13.6 billion in its latest quarter, more than $1 billion more than Wall Street expected.

A supercomputer in Shenzhen was declared the world’s fastest. It uses only standard microprocessors and not the special-purpose chips called graphics processing units.

Industry leaders had worried that innovations in chip miniaturization were no longer possible.

Advanced chip packaging, which boosts computing power for artificial intelligence, has made the United States more reliant on Taiwan than ever.

The Silicon Valley chipmaker’s revenue rose 25 percent in the latest quarter, its fastest growth in 15 years, as A.I. firms increasingly bought chips known as central processing units.
