The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The MX-1 was launched at a markedly lower price (by 62 percent) than the G1X Mark III, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Pentax MX-1 a 1/1.7-inch sensor. The sensor area in the MX-1 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 4.5. The sensor in the G1X Mark III has a native 3:2 aspect ratio, while the one in the MX-1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the G1X Mark III offers a higher resolution than the MX-1 (12MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.89μm for the MX-1) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 4 years and 9 months) than the MX-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon G1 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Pentax MX-1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Pentax MX-1 are ISO 100 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G1X Mark III provides a higher frame rate than the MX-1. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the MX-1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G1 X Mark III and Pentax MX-1 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark III has a touchscreen, while the MX-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark III has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the MX-1 does not have a selfie-screen.
The Canon G1 X Mark III has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Both the G1X Mark III and the MX-1 have zoom lenses built in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the MX-1 offers a 28-112mm f/1.8-2.5 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Pentax, but less tele-photo reach at the long end. The MX-1 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X Mark III and the MX-1 write their files to SDXC cards. The G1X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the MX-1 cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G1 X Mark III and Pentax MX-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the match-up (22 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G1X Mark III or the MX-1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
