 - Benefit from the smaller model, the Cache hit rate is improved and inference would be faster
 - Chips tend to have corresponding fixed-point acceleration instructions which are faster and less energy consumed (int8 on a common CPU requires only about 10% of energy)
 
-The size of the installation package and the heat generation are the key indicators of the mobile terminal evaluation APP;
-On the server side, quantization means that you can maintain the same QPS and improve model precision in exchange for improved accuracy.
