Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The two cameras under review were launched at the same price and fall into the same market segment. 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.
Sensor comparison: Canon G3 X vs Sony RX100 IV
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras 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.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.
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 G3X and the RX100 IV have the same pixel density, as well as the same pixel size. Moreover, the two cameras were released in close succession, so that their sensors are from the same technological generation.
The Canon PowerShot G3 X 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 Sony Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600..
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. Of the two cameras under consideration, the RX100 IV has a markedly higher DXO score than the G3X (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1.4 bits higher color depth, 0.3 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX100 IV provides a better video resolution than the G3X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Feature comparison: Canon G3 X vs Sony RX100 IV
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G3 X, the Sony RX100 IV, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X has a touchscreen, while the RX100 IV has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the RX100 IV features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
Both the G3X and the RX100 IV have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 IV offers the faster maximum aperture.
The G3X writes its imaging data to SDXC cards, while the RX100 IV uses SDXC or Memory Stick PRO Duo cards.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
