M1
Apple's first self-designed ARM-based SoC, released in 2020, integrating CPU, GPU, Neural Engine and unified memory. It marked the Mac product line's transition from Intel processors to Apple-designed chips.
Core Facts
Apple's launch of the M1 chip in 2020 was the first to prove the viability of ARM architecture on PCs.
Starting with the M1 chip, Apple uses a Unified Memory Architecture (UMA) where the CPU, GPU, and Neural Engine share the same memory pool.
Timeline (last 90 days)
The same 7B model may run several times differently on a base M1 versus an M3 Max.
An M1 machine running macOS 26 uses approximately 9.1 GB of memory at startup.
Apple's M1 through M4 series chips have established a significant advantage in energy efficiency, enabling MacBook to achieve battery life and performance that surpasses x86-architecture competitors within the same weight class.
Apple Intelligence requires a Mac with an M1 or later chip; Intel Macs from before 2020 cannot use AI features.
Starting with the M1 chip, Apple uses a Unified Memory Architecture (UMA) where the CPU, GPU, and Neural Engine share the same memory pool.
