The CPU uses the AArch64 or ARM64 extension set of the ARM architecture. Likewise, you are probably used to integrated GPUs as well, as they’ve been used in Intel and AMD chips for years. The GPU used in the Apple M1 has eight cores and takes up just a bit more space on the chip than the eight CPU cores.
How do I know if my Mac is ARM or x86?
If you see Apple M1(or higher) in the “Chip” section, it means you’re using a Mac with an Apple Silicon CPU. If you see an Intel processor in the “Processor” section, it means you’re using a Mac with an Intel chip. And that’s how easy it is to know if you’re using a Mac with an Apple Silicon CPU or an Intel processor.

What is ARM64 bit Mac?
On macOS, two architecture are supported: x86_64 is the architecture of Intel’s 64-bit CPUs, sometimes also simply referred to as x64 . It is the architecture for all Intel Macs shipped between 2005 and 2021. arm64 is the architecture used by newer Macs built on Apple Silicon, shipped in late 2020 and beyond.
Is Mac an ARM64?
The Mac transition to Apple silicon is the process of changing the central processing units (CPUs) of Apple Inc.’s line of Mac computers from Intel’s x86-64 processors to Apple-designed systems on a chip that use the ARM64 architecture.
