How to use it
- Enter frequency and unit.
- Enter IPC and optional core count.
- Calculate per-core and total estimates.
Instruction Throughput Calculator
Estimate ideal instruction rate from clock frequency and IPC.

About the Instruction Throughput Calculator
This tool multiplies ideal clock cycles by stated instructions per cycle.
Formula
Throughput equals frequency times IPC times cores.
Example
3 GHz at 2 IPC gives 6 billion instructions per second per core.
Notes
Real performance depends on workload, memory, compiler and architecture and will not equal this theoretical ceiling.
