Final answer:
CPU differences between manufacturers include architecture, processing speed, power efficiency, manufacturing process, and unique technologies like integrated graphics.
Step-by-step explanation:
Other than size, central processing units (CPU) differ between manufacturers based on several factors. One key difference is architecture, which refers to the design and structure of the CPU, affecting how it processes instructions and interacts with other computer components. Other variations include processing speed, measured in instructions per second, and power efficiency, representing how much electrical power a CPU uses to perform a task.
The manufacturing process is also a differentiator; with companies like Intel and AMD using different technology nodes measured in nanometers, affecting the CPU's performance and power consumption. Finally, CPUs from different manufacturers often have unique features and technologies such as integrated graphics, security enhancements, and support for virtualization.
