Actually they're not so much faster -- although the camera companies don't have the economies of scale to iterate nearly as fast as the phone companies (so they hang onto a processor generation for a couple of years). A good smartphone can capture 4K video or 20fps 8MP or whatever off the sensor — both around 160MB/s. A $10k DSLR is handling 16MP at 11fps — that's around 300MB/s (remember that the DSLR is handling 14-bits per sensel). The interesting thing is that if you look across the camera lineups, there's almost no difference in CPU between a $300 consumer camera and a $10k professional (there is a big difference in RAM - the DSLR is able to store 50+ uncompressed images in RAM (let's say 3-4GB), while the phone or low end camera processes them into JPEG before storage.
