The GM5 was revealed 3 years later than the S3 and that is quite a big gap as far as technology is concerned. Each of the cameras come with different body type with the Panasonic GM5 being a Rangefinder-style mirrorless camera and the Panasonic S3 being a Compact camera.

Before diving straight into a comprehensive comparison, below is a brief overview of how the GM5 scores vs the S3 in the way of portability, imaging, features and an overall rating.

Following is a sample of the gallery pictures for Panasonic Lumix DMC-GM5 and Panasonic Lumix DMC-S3. The full galleries are provided at Panasonic GM5 Gallery and Panasonic S3 Gallery.

Sometimes, its difficult to visualize the contrast between sensor sizing purely by reading a spec sheet. The visual underneath will help offer you a clearer sense of the sensor measurements in the GM5 and S3.

As you can see, both of these cameras have got different megapixels and different sensor sizing. The GM5 having a larger sensor is going to make shooting shallower DOF easier and the Panasonic GM5 will offer greater detail because of its extra 2 Megapixels. Greater resolution will help you crop pics much more aggressively. The younger GM5 provides an advantage with regard to sensor innovation.
