Memory Bandwidth
Calculate theoretical aggregate bandwidth from transfers per second, bytes per transfer, and active channels. Output is decimal GB/s (10⁹ bytes/s); protocol overhead and idle cycles are excluded.

When to use Memory Bandwidth
Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.
- Transfers per second
- Required number input.
- Bytes per transfer
- Required number input.
- Parallel channels
- Required integer input.
How Memory Bandwidth works
Calculate theoretical aggregate bandwidth from transfers per second, bytes per transfer, and active channels. Output is decimal GB/s (10⁹ bytes/s); protocol overhead and idle cycles are excluded. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Bandwidth Bytes Per Second
- The resulting bandwidth bytes per second returned as a number.
- Bandwidth Gb Per Second
- The resulting bandwidth gb per second returned as a number.
Limitations and assumptions
- Signal-integrity estimates depend on edge rate, channel loss, impedance discontinuities, termination, encoding, equalization, clock recovery, jitter decomposition, crosstalk, connectors, vias, and receiver masks. Aggregate budgets must use compatible statistical or worst-case conventions.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.
