Samsung NX100 has a 15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIMe Engine processor. On the other hand, Canon 5D MIII has a 22.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 5+ processor.
Canon 5D MIII's sensor provides 7MP more than Samsung NX100'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.
Below you can see the NX100 and 5D MIII sensor size comparison.

Sensor Size and Resolution Comparison image of Samsung NX100 and Canon 5D MIII Cameras
As seen above, Canon 5D MIII has a 2.4x Larger sensor area than Samsung NX100. 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Samsung NX100 and Canon 5D MIII sensors have been tested by DxO and the results show that 5D MIII has a better overall score of 81, 19 points higher compared to NX100's score of 62.
