A recent snapshot posted by Weibo user @DOSPY-山雨独酌 shows that the Huawei Mate 7’s processor is the Kirin 926. Based on the fact that this device has 3GB RAM and 32GB ROM, this must be the high-end version of the Mate 7.
So, what upgrades were made for the Kirin 925? It is bound to have a stronger GPU than the Kirin 920. Instead of the Kirin 920’s Mali-T628MP4 GPU, it should have the stronger Mali-T628MP6 GPU.
Although the Kirin 920 is a pretty good processor, its GPU is not very strong. If the Kirin 925 has stronger GPU then it should have better power consumption.
