Apple M4 is an ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, including a central processing unit (CPU), a graphics processing unit (GPU), a neural processing unit (NPU), and a digital signal processor (DSP). It was introduced in May 2024 for the iPad Pro (M4), and is the fourth generation of the M series Apple Silicon architecture, succeeding the Apple M3.^[2][3][4]

According to Apple, the M4 SoC's Neural Engine is capable of 38 trillion operations per second, "which is 60x faster than Apple’s first Neural Engine in the A11 Bionic chip." The SoC is built upon a 3-nanometer process, and features 3 or 4 performance cores, 6 efficiency cores, and 10 graphics processing cores.^[5]

The M4 is the world's fastest consumer SoC in single core performance according to the Geekbench benchmarking suite,^[6] (beating Apple's M3 Max and Intel's Core i9 desktop CPUs), and compares to Apple's M3 Pro in multi-core performance.^[7]

It is the first iPad SoC to support AV1 decode, and has a new display controller that Apple claims is necessary to support the iPad Pro (7th generation)'s Tandem OLED display.^[5]

The M4 is Apple's first SoC which uses the ARMv9 architecture for its CPU cores, specifically ARMv9.2-A.^[8]
