Use this tool to calculate the memory bandwidth
Enter the following:
- Memory Clock Frequency – this is the clock frequency (in MHz) that is input to the memory module
- Bus Width in bits
- Clock multiplier is a factor depending on the memory type. In the case of DDR for instance this number is 2.
Memory Bandwidth = Clock Frequency * Multiplier * Bus Width * (1/8)
For a clock frequency of 500 MHz; multiplier of 2 and Bus Width of 256 Bits, the memory bandwidth is 32 GB/s.
