A 13 bit PCM system performance is better than an 8 bit PCM system because:
1
Noise is lower and is proportional to reciprocal of bandwidth
2
Bandwidth is larger and detection is easier
3
Quantization noise is lesser other things being equal
4
Quantization noise is nearly zero since 213 levels are available
