CPU vs. Microprocessor: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 13, 2024
CPU is central Processing Unit, the primary component of a computer handling instructions. Microprocessor is a single integrated circuit containing a CPU, often with additional features.
Key Differences
CPU (Central Processing Unit) is often referred to as the brain of the computer, executing instructions from software. Microprocessors are more specific, being single-chip CPUs with integrated functions like memory management.
Microprocessors represent an evolution in technology, integrating the entire CPU onto one chip for efficiency. CPUs, traditionally, could be multi-chip assemblies, handling core processing tasks.
CPUs are a broader term encompassing various types of processors, including those in smartphones and embedded systems. Microprocessors, on the other hand, specifically refer to single-chip solutions often used in personal computers.
Microprocessors often include features beyond the basic CPU functions, like graphics processing units (GPUs) and memory controllers. In contrast, CPUs might only focus on processing instructions and leave other tasks to separate chips.
CPUs are fundamental to computing, executing instructions and running software. Microprocessors enhance this by offering compact, integrated solutions, making them ideal for personal computing and electronic devices.
