Unlike the motherboard/CPU/memory model common inside most PCs, iPhones and the latest Macs are based on SoCs. Most people think of a chip as technically a package that holds a die (sometimes more than one) and the wires to connect the die to the rest of the system. Quick glossary minute: A die is the actual semi-conductive material that does the work. It doesn't make sense to pair a super-fast CPU with generic, middle-of-the-road memory because the memory bus won't be able to handle what the CPU throws at it. If you've ever built a PC, you probably know that it doesn't make sense to pair a high-end GPU with a mediocre CPU because the CPU will bog down the graphics. The car may be one of the world's fastest cars, but if the road is bottlenecked, it's not going anywhere. It's like driving a Koenigsegg Agera RS in rush hour.
That's a wild over-simplification because even though a super-fast CPU might process instructions and calculations at warp speed, if it takes the system bus forever to move data around, it doesn't matter. Generally speaking, the faster the CPU, the faster the machine.

But basically, at the center of it all is the CPU.Īlso: Introducing my design for an Apple Silicon-based Mac Pro In practice, modern computers have many processors, but some are used for special purpose calculations (like your GPU for graphics).
The CPU processes sequences of instructions, does calculations, makes decisions, and tells data to move. The processor, the central processing unit (or CPU), orchestrates all of these elements.
