Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X was launched at a somewhat lower price (by 13 percent) than the G1X, which makes it more attractive for photographers on a tight budget. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X is 56 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.7. The sensor in the G1X has a native 4:3 aspect ratio, while the one in the G7X offers a 3:2 aspect.
Technology-wise, the G7X uses a more advanced image processing engine (DIGIC 6) than the G1X (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixels, compared with 14.2 MP of the G1X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.30μm for the G1X). However, it should be noted that the G7X is much more recent (by 2 years and 8 months) than the G1X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.
The Canon PowerShot G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot G7 X are ISO 125 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 offers substantially better image quality than the G1X (overall score 11 points higher). The advantage is based on 1.3 bits higher color depth, 1.9 EV in additional dynamic range, and 0.2 stops of reduced 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7X provides a faster frame rate than the G1X. It can shoot movie footage at 1080/60p, while the G1X is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G1 X and Canon G7 X in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the G1X 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 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 G1X and the G7X have zoom lenses built in. The G1X has a 28-112mm f/2.8-5.8 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G7X provides a wider angle of view at the short end than the G1X, but less tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X and the G7X write their files to SDXC cards. The G7X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1X 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 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 G1X has a hotshoe, while the G7X does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the G1X and the G7X have been discontinued, but can regularly be found used on eBay. The G1X was replaced by the Canon G1X Mark II, while the G7X was followed by the Canon G7 X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is the Canon G1 X better than the Canon G7 X or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon PowerShot G1 X:
- Easier framing: Has an optical viewfinder for image composition and settings control.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the contest (19 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 G1 X and the Canon G7 X place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G1X or the G7X 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
