== Bandwidth figures

26
There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU.

To build it:
29
30
{{{
31
cd gr-fosphor/lib/fosphor
32
make
33
}}}
34
35
Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format.

Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console.

Submit your numbers & help us to create a GPU survey. We are especially interested in the top end and mobile graphics figures.
