Apple M4 is a series of 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).
[6] The M4 series is built upon TSMC's second-generation 3-nanometer process and contains 28 billion transistors.
The SoC also includes a 10-core GPU (with hardware-accelerated ray tracing, dynamic caching, and mesh shading introduced with the M3), as well as a 16-core NPU.
[8] The M4 Neural Engine has been significantly improved compared to its predecessor, with the advertised capability to perform up to 38 trillion operations per second, claimed to be more than double the advertised performance of the M3.
The M4 Pro is available with up to 64GB unified memory (Mac Mini) with a theoretical maximum bandwidth of 273GB/sec.
