Amazon and Apple shift from Intel chips, change in driving industry

“Intel is building on more than 20 years of x86-based ecosystem work,” Lisa Spellman, an Intel corporate vice president. “We ensure software compatibility and high performance, critical requirements for both consumers and data center customers.”

Amazon continues to expand its use of Intel chips for certain jobs. It announced plans on Tuesday to run Intel-powered Mac Mini computers in its data centers so that programmers could develop software for Apple systems without using Apple hardware.

But Rene Haas, president of Arm’s core product group, said that Arm is competitive in computing. He said that Arm had made significant changes to improve the computing performance of each processor core, or put different calculation engines on each piece of silicon.

Cloud-style computing works can also take advantage of relatively simple cores and lots of special purpose circuitry, Mr. DeSantis of Amazon said. He said that its arm-based chip, Graviton 2, has 64 cores compared to 24 more powerful cores on Intel server chips. It helps in performing computing tasks simultaneously, such as serving web pages to different people.

Ampere, a chip start-up in Santa Clara, California, has developed an 80-core arm server chip and expects to release a 128-core version next year. Ampere’s chief executive Renee James said its customers and investors include software giant Oracle, which plans to offer cloud computing services based on Ampere’s chips.

“Real with Amazon,” Ms. James said. “His competitors will follow suit.”

Gervard Williams III, chief executive of Nuvia, another start-up promoting arm-based chips, said arm backers also benefited Intel loses leadership in driving manufacturing innovations That chips make more at a lower cost. Chip makers such as Taiwan Semiconductor Manufacturing Company and Samsung Electronics can now work more on each slice of silicon, meaning arm chip designers who use them can gain speed gains.

Change is visible in many forms of computing. In laptop computers from research firm Gartner, it was predicted that by 2024, Apple’s new Macs and rivals’ responses would push arm-based PCs to 13.5 percent of the market, up 1.1 percent this year.
