Memory Bandwidth Calculator

Calculate your computers memory bandwidth quickly and easily.
Now able to calculate both system and GPU bandwidth.
Supports DDR1, DDR2, DDR3, DDR4, as well as single through to quad channel configurations.

Work out whether or not your memory is a bottleneck, or find out just how much bandwidth you can get from overclocking.

It's simple, all you need to do is select how many memory channels you have, then enter your frequency (the advertised frequency).

For example, if I had a 1600mhz kit of two, I'd select 2 channels and type 1600 for the frequency.

Or for a GPU, I'd simply hit the GPU button, then type in the frequency and select how wide the bus is, so for a R9 290X I'd type 5000, then select 512 bit.
