According to macrumors, Jean-Louis Gassée, a former Apple executive and founder of Be, elaborated on Apple's possible shift to ARM-based Macs in the near future.
There are rumors that Apple will launch an ARM-based Mac computer as early as 2021.
Gassée explained that he had previously been skeptical that ARM-based processors would rival Intel products, but now he realized he was wrong. He mentioned Ampere Computing, a semiconductor company led by former Intel president Renee James. The company designed ARM-based high-power processors to compete with high-end Intel chips.
He said that compared to the 400 watts of power required by similar Xeon CPUs, Ampere's top-of-the-line chips of the same order of magnitude have lower power consumption, about 210 watts. Ampere showed the industry that the ARM architecture can meet the requirements of the chips required by the Mac Pro. Apple will of course customize its own ARM processor, but Ampere seems to be pushing the performance limits of the ARM architecture.
Reports from Bloomberg said that rumors about Apple's use of ARM-based chips on Macs began in 2018, and recent rumors point to 2021.
