Carrying the model number CND-AN00, the said phone was recently certified by TENAA, with almost all of the specs being identical to the current Nova 7 SE. The main difference here is that this version uses a Dimensity 800U processor instead of the Kirin 820.
This change would mean that the MediaTek-powered Nova 7 SE will be cheaper than the Kirin-powered version. To recap, the Kirin 820 has one prime Cortex-A76 processor running at 2.36Ghz, three Cortex-A76 cores running at 2.22Ghz, and four Cortex-A56 cores running at 1.8Ghz, while the Dimensity 800U has two Cortex-A76 cores at 2.4Ghz and six Cortex-A55 cores at 2.0 GHz.
Why the different processor variant? This is most likely because Huawei is saving its stock of Kirin processors for its flagship models, as it Taiwan semiconductor manufacturer TSMC will stop making chips for Huawei due to the US Trade Ban that will go in full effect on September 15.
