The current M1 chip inherits a mobile-centric design built around four high-performance processing cores to accelerate tasks like video editing and four power-saving cores that can handle less intensive jobs like web browsing. For its next generation chip targeting MacBook Pro and iMac models, Apple is working on designs with as many as 16 power cores and four efficiency cores, the people said.
While that component is in development, Apple could choose to first release variations with only eight or 12 of the high-performance cores enabled depending on production, they said. Chipmakers are often forced to offer some models with lower specifications than they originally intended because of problems that emerge during fabrication.
For higher-end desktop computers, planned for later in 2021 and a new half-sized Mac Pro planned to launch by 2022, Apple is testing a chip design with as many as 32 high-performance cores.
With today’s Intel systems, Apple’s highest-end laptops offer a maximum of eight cores, a high-end iMac Pro is available with as many as 18 and the priciest Mac Pro desktop features as much as a 28-core system. Though architecturally different, Apple and Intel’s chips rely on the segmentation of workloads into smaller, serialized tasks that several processing cores can work on at once.
Advanced Micro Devices Inc., which has been gaining market share at Intel’s expense, offers standard desktop parts with as many as 16 cores, with some of its high-end chips for gaming PCs going as high as 64 cores.
