Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung NX3000 is significantly lighter (427g ) than the Sony A7R III which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Sony A7R III has a Full frame sensor and Samsung NX3000 has a smaller APS-C sensor, Samsung NX3000's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7R III lenses.

LCD Screen Size and Features
Sony A7R III and Samsung NX3000's LCD screens has the same diagonal size of 3.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over the head levels.
Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Samsung NX3000 has a 20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Sony A7R III's sensor provides 22MP more than Samsung NX3000's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Another difference between these two cameras is that Sony A7R III's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

As seen above, Sony A7R III has a 2.3x Larger sensor area than Samsung NX3000. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Sony A7R III has an advantage over Samsung NX3000. There are 127 lenses for Sony A7R III's Sony E mount, on the other hand there are only 32 lenses for Samsung NX3000's Samsung NX lens mount.
Another important factor is the availability of image stabilization. Sony A7R III has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. A7R III's built-in Image stabilization system is effective to compensate vibration up to 5.0-stops according to CIPA standards.7 lenses for Samsung NX mount with Optical Image Stabilization features.
