The a1 was manufactured 11 years after the TX7 which is quite a sizable gap as far as tech is concerned. Both of these cameras offer different body type with the Sony a1 being a SLR-style mirrorless camera and the Sony TX7 being a Ultracompact camera.

Before going through a detailed comparison, below is a concise summary of how the a1 grades versus the TX7 when considering portability, imaging, features and an overall score.

Here is a preview of the gallery images for Sony Alpha a1 and Sony Cyber-shot DSC-TX7. The entire galleries are available at Sony a1 Gallery and Sony TX7 Gallery.

If you are intending to carry around your camera regularly, you'll need to take into account its weight and proportions.

Oftentimes, it is very hard to visualise the contrast between sensor sizes simply by checking a spec sheet. The image underneath should provide you a much better sense of the sensor measurements in the a1 and TX7.

Clearly, both the cameras enjoy different megapixel count and different sensor sizes. The a1 because of its bigger sensor will make shooting shallower DOF simpler and the Sony a1 will resolve greater detail due to its extra 40MP. Higher resolution will also allow you to crop shots far more aggressively. The newer a1 will have a benefit when it comes to sensor innovation.
