I read many times Cameras can do higher frame rates in lower bit-depths as example Apertus:

See
Cmosis CMV12000
"Up to 300 (10 bit), 132 (12 bit) FPS at Full Resolution"
How Bit-Depths related to FPS ?
Is this about data transfer speed? Sensor can do 300 FPS at 12 bit but the processor or something else (buffers) can't handle it because of the data amount at 12-bit compared to 10-bit with less data and more FPS?
Explanation needed @a1ex :D
