What 200 mp phone camera sensors? The iPhone 14 is closer to a 12MP digital camera (quad bayer 48 million sensors). And from what I recall, 8 or maybe 10 bit. So in comparison to the 211MB of sensor data coming off the R5, there's 36 to 45MB of data coming off the phone camera. And I believe the 14's max shutter speed is 1/1000, so there's up to 35 times less data needing to be read off the sensor (45GB/s versus 1.6TB/s)

And I'm sure there is multiple processing paths - I just don't know the fine details about how that raw data is slurped off the sensor.
