Nope. The DP12 is by far faster to cycle through the rounds. And if you set the upper limit of rounds, the DP12 is more than twice as fast. Youtube videos show the result, https://www.youtube.com/watch?v=HPwi1AsIy_0
I have shot a DP-12 and own an 870. The big difference one has to get used to is the pump, bang, bang, then pump.
For starters, let's make the assumption the DP-12 is a tactical weapon and not a sporting or hunting firearm. Then magazine capacity is king. I recently watched the Magpul Dynamics DVD series, "The Art of The Dynamic Shotgun" and the two instructors commented that the essential element of shotgun deployment is magazine capacity and reloading. They say "you are either shooting your weapon or reloading it" in a fighting situation. BTW, these guys were clearly ex-military.
But I would still put money on a DP-12 to out gun a semi-auto to achieve a faster time with 14 rounds. Even an 8 round semi would need a combat reload of 6 single rounds which is vastly slower than a pump, bang, bang, rinse and repeat.
If you needed more rounds than what the DP-12 holds however, a conventional pump or semi would be much faster to get back into action given how relatively slow loading the DP-12's magazines appears to be, and the inability to quickly port load it while its in firing position.
Performing a slug swap appears to be a bit of an issue as well.
