Body comparison: Sony RX100 vs Canon G7 X
The physical size and weight of the Sony RX100 and the Canon G7 X are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G7 X is somewhat larger (4 percent) than the Sony RX100. Moreover, the G7X is markedly heavier (27 percent) than the RX100. In this context, it is worth noting that neither the RX100 nor the G7X are weather-sealed.
Concerning battery life, the RX100 gets 330 shots out of its NP-BX1 battery, while the G7X can take 210 images on a single charge of its NB-13L power pack. The power pack in the RX100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 RX100 was somewhat cheaper (by 7 percent) than the G7X at launch, but both cameras fall into the same price category. 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.
Sensor comparison: Sony RX100 vs Canon G7 X
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the RX100 and the G7X have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X is much more recent (by 2 years and 3 months) than the RX100, and its sensor will have benefitted from technological advances during this time.
The Sony Cyber-shot DSC-RX100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot G7 X are ISO 125 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the G7X has a markedly higher DXO score than the RX100 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.3 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the RX100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the RX100 does not have a selfie-screen.
The Canon G7 X 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 RX100 and the G7X have zoom lenses built in. The RX100 has a 28-100mm f/1.8-4.9 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Sony and the same tele-photo reach at the long end. Both cameras offer the same maximum aperture.
The RX100 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the G7X uses SDXC cards. The G7X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX100 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison: Sony RX100 vs Canon G7 X
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 Sony Cyber-shot DSC-RX100 and Canon PowerShot G7 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the RX100 does not offer wifi capability.
Both the RX100 and the G7X have been discontinued, but can regularly be found used on eBay. The RX100 was replaced by the Sony RX100 II, while the G7X was followed by the Canon G7 X Mark II. Further information on the two cameras, as well as related accessories, can be found on the official Sony and Canon websites.

Do the specifications of the Sony RX100 and the Canon G7 X place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing.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 RX100 or the G7X perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
