Throughput vs. Capacity — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on November 6, 2023
Throughput refers to the rate at which data is processed or goods are produced over time, while capacity is the maximum amount that can be contained or produced.

Key Differences
Throughput refers to the amount of material or items passing through a system or process from start to finish over a certain period. Capacity, however, is the maximum output that a system or process can handle under ideal conditions. Throughput is about efficiency and flow, whereas capacity is about potential and scale.
Throughput is measured by the rate of production or processing, such as Mbps in data transfer or units per hour in manufacturing. Capacity, conversely, defines the limit of production or processing, like the maximum data bandwidth or the total volume a facility can handle at once. Throughput is operational, while capacity is more about infrastructure.
While throughput can vary according to the system's efficiency, capacity is often a fixed value determined by physical or design constraints. A system's throughput can never exceed its capacity, as capacity sets the upper boundary for throughput. Throughput changes with actual conditions; capacity represents a theoretical maximum.
In a practical scenario, throughput could refer to the actual number of cars passing over a bridge in an hour, while capacity would be the maximum number of cars that could pass if the bridge were fully utilized. Throughput is dynamic and changes in real-time; capacity is static until the system is upgraded.
Throughput and capacity are interrelated; high capacity does not guarantee high throughput, which can be affected by other factors such as system management or operational efficiencies. In computing, throughput might refer to actual data transmitted over a network, whereas capacity would be the network's maximum data carrying capability.
