How fast can GPIO pins toggle?
If you want to synchronously transmit data at 50MHz frequency (that's how I read "pins to be toggled on the schedule of a ~50 mhz FPGA clock"), you will absolutely need to use the same clock source ...

Benchmark on one machine too extreme
Running that command to bench your RPi is not so acurate. That command will burn 1/4 cores of your Pi, thats why you get weirds results. Try to activate all 4 cores at 100%.
