Apple unveiled new MacBook Pro laptop computers powered with its M1Pro and M1Max chips.
Apple says the M1 Max chip, with 57 billion transistors, is the most powerful it has ever built.
The new chips were announced almost a year after the firm revealed its first Mac computers powered by silicon of its own design.
It comes after reports that Apple cut its iPhone 13 production targets amid the global computer chip shortage.
Industry analyst Mikako Kitagawa of Gartner said “the performance boost is pretty impressive”.
Apple claims the new chips will achieve comparable performance to the latest 8-core PC laptop chip running at top speed while using 70% of the power.
Going flat-out the chip, the company claimed, would be up to 1.7 times faster than the 8-core PC chip.
For years Apple has used chips designed by Intel. The move to designing its own silicon has been positive for the firm, according to Ben Wood, chief analyst of CCS Insight.
“The advent of Apple Silicon has been a shot in the arm for the MacBook line-up,” he said.
The two chips power the new 14in and 16in MacBook Pro laptops and a new operating system, macOS Monterey.
In the “Unleashed” launch presentation Apple stressed the MacBook’s power and long battery life.
The MacBooks were unveiled at a time when the company has warned of the impact of the global chip shortage.
Previously Apple boss Tim Cook said that the issue could affect products using M1 chips. Recent reports suggest that the shortage might hit iPhone 13 production.
