Canon has redesigned the camera's mirror mechanism to reduce the amount of vibration it causes when it flips up. Using a similar system to the one employed in the EOS 7D II, it is motor, rather than spring driven. This means its upward motion can be decelerated as it approaches the top of its travel, rather than smacking against a stop at full speed. We're fairly convinced that this new design helps maintain image sharpness despite the high resolution of the camera, especially in Silent Shooting mode.
