Leica M8 has a 10.0MP APS-H (27 x 18 mm ) sized CCD sensor . You can shoot at maximum resolution of 3936 x 2630 pixels with aspect ratios of and 3:2. M8 has a native ISO range of 160 - 2500 and it can save files in RAW format which gives you a wider room for post processing.
Leica M8 is not the highest resolution APS-H camera. Sigma Quattro H with its 45.0MP sensor is leading in this class. Check the comparison of Leica M8 vs Sigma Quattro H or take a look at Highest resolution Mirrorless cameras list.
Leica M8 DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. Leica M8 sensor has been tested by DxO Mark and got an overall score of 59 for its image quality. You can find the details of their analysis of Leica M8 here.
Anti-Aliasing Filter
Another important feature about Leica M8's sensor is the lack of anti-alias (Low-pass) filter. Removing anti-aliasing filter increases the sharpness and level of detail but on the other side it also increases the chance of moiré occurring in certain scenes.
Let's look at how the size of the Leica M8's APS-H sensor compares with other standard sensor sizes.

Sensor size is what determines the circle of confusion, and therefore how much
depth of field Leica M8 gives you at any given aperture.

the exact depth of field for the Leica M8
at any focal length, aperture and subject distance, including the hyperfocal distance
for landscapes and the very shallow focus zone you get with long telephoto lenses.
