The M1 chip is Apple’s first-generation custom ARM-based system-on-a-chip, manufactured by Apple Inc. using 5-nanometer process technology. Launched in November 2020, the M1 marked Apple’s historic transition from Intel processors to its own custom Apple Silicon, bringing unprecedented performance and efficiency to Mac computers.
The M1 features 8 CPU cores (4 high-performance and 4 energy-efficient cores), up to 8 GPU cores, and a 16-core Neural Engine capable of 11 trillion operations per second.
Introduced between 2020-2021, M1-powered iMacs showcase revolutionary features including unified memory architecture supporting up to 16GB RAM, advanced image signal processor, Secure Enclave for data encryption, hardware-accelerated H.264 and HEVC encoding/decoding, and remarkable energy efficiency that eliminates the need for cooling fans while delivering performance rivaling traditional desktop processors.
