Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G7X Mark II was launched at a somewhat lower price (by 22 percent) than the GR III, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 G7 X Mark II features an one-inch sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the GR III offers a higher resolution than the G7X Mark II (20MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the GR III is a much more recent model (by 3 years) than the G7X Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GR III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Canon G7 X Mark II are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 cm for excellent quality prints.
The GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G7 X Mark II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a variety of features. The G7X Mark II and the GR III are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Canon G7 X Mark II and Ricoh GR III along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G7X Mark II has one, while the GR III does not. While the built-in flash of the G7X Mark II is not very powerful, it can at times be useful as a fill-in light.The G7X Mark II 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 GR III does not have a selfie-screen.
The Canon G7 X Mark II and the Ricoh GR III both have 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.
The G7X Mark II is equipped with a zoom lens, while the GR III comes with a built-in prime. The G7X Mark II has a 24-100mm f/1.8-2.8 optic and the GR III offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The G7X Mark II offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X Mark II and the GR III write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 G7 X Mark II and Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The G7X Mark II does not feature such an accessory-socket.
The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the G7X Mark II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G7X Mark II was succeeded by the Canon G7 X Mark III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon G7 X Mark II and the Ricoh GR III? Which camera is better? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the GR III emerges as the winner of the match-up (14 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.
How about other alternatives? Do the specifications of the Canon G7 X Mark II and the Ricoh GR III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X Mark II or the GR III. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
