The speed of a CPU is typically measured in MHz (Megahertz) or GHz (Gigahertz). This represents the number of clock cycles the CPU can perform per second. A higher clock speed generally indicates a faster CPU.
Several factors can affect CPU speed:
- Clock Speed: As mentioned above, a higher clock speed allows the CPU to execute more instructions per second.
- Number of Cores: Modern CPUs often have multiple cores. Each core can execute instructions independently, allowing the CPU to handle multiple tasks simultaneously. More cores generally lead to better performance.
- Cache Size: A larger cache allows the CPU to store more frequently accessed data, reducing the need to access slower main memory.
- Architecture: The design of the CPU (its architecture) can significantly impact its performance. Newer architectures are often more efficient and can execute instructions faster.
- Manufacturing Process: Smaller transistors (resulting from advanced manufacturing processes) can be packed more densely on the chip, leading to faster speeds and lower power consumption.
Example of a unit of measurement: 3.5 GHz (meaning the CPU can perform 3.5 billion clock cycles per second).
