Partially stacked sensors are essentially conventional BSI sensors with more complex readout circuitry (seen at the top and bottom of the Z6III sensor, here). This allows boosted DR modes we're seeing from the Panasonic S1II and Sony a7 V. Image: Nikon Dynamic range data for the Sony a7 V makes clear that the benefit of partially stacked CMOS isn't just speed: it's the ability to deliver higher dynamic range...
