What Is A Supercomputer?

Published

on



China held the lead for the last 5 years, but the United States now has the world’s fastest supercomputer. The machine, called Summit, was built for Oak Ridge National Laboratory in partnership with IBM and NVidia, and is designed for AI applications.

Today’s supercomputers are made up of thousands of connected processors, and their speed has grown exponentially over the past few decades. The first supercomputer, released in 1964, was called the CDC 6600. It used a single processor to achieve 3 million calculations per second. While that may sound impressive, it is tens of thousands of times slower than an iPhone.

The Lab Director of Oak Ridge, Thomas Zacharia, says, “I’ve always thought of supercomputing as a time machine, in the sense that it allows you to do things that most other people will be able to do in the future.” As he explains, smartphones today are more powerful than the supercomputers used in the 1990s to work on the Human Genome Project.

Inside SK Hynix: We Went To Korea To See The World’s Biggest AI Memory Buildout

Published

on

By



South Korean chip giant SK Hynix, which makes the majority of the world’s high-bandwidth memory chips for artificial intelligence, is undergoing the world’s largest memory fab buildout, betting $720 billion to triple capacity by 2034. This secretive memory king is also the hottest new entrant to the U.S. market, following a blockbuster Nasdaq debut in July.

SK Hynix, whose market cap has jumped more than fivefold in the past year and now tops $1 trillion, is making a big bet that extreme demand from AI is here to stay. Soaring memory prices exacerbated by capacity constraints are changing the fabric of the classic boom-and-bust industry, with AI chip giants like Nvidia willing to take on more risk as they scramble to secure supply. This is a never before seen look inside the highly secured company from the largest factory being built in South Korea to an inside look at a cleanroom where memory is made, to SK Hynix’s first ever U.S. facility coming in Indiana.

Plus, CNBC’s Katie Tarasov got a rare chance to sit down with SK Group Chairman Chey Tae-won and SK Hynix technology leads to ask about the huge risks they’re taking in hopes that AI has changed the memory business for good.
