DxOmark (Click here) published the full Panasonic LX100 sensor test:
Adopting a larger sensor than the lens can cover offers advantages in lens size and speed, but the trade-off is somewhat reduced sensor performance, particularly in respect to low-light capabilities. For all that, it’s still no worse than rival offerings, given that neither the Sony Cyber-shot RX100 III nor the Canon Power-Shot G1 X Mark II fare any better in low light. If that’s a restriction for your type of photography, larger sensor compacts such as the APS-C Ricoh GR and particularly the full-frame Sony DSC-RX1/1Rhave better performance, but there are tradeoffs, not the least being the daunting premium price for the Sony.
