The chip is expected to utilize an octa-core CPU configuration leveraging ARM cores. This includes one Cortex X925 core at 3.2GHz, three Cortex A725 cores at 2.6GHz, and four Cortex A520 cores at 2.0GHz.

The prime core is the same MediaTek uses in its latest Dimensity 9400 while the high-performance and efficiency cores are from a generation back. So while Xiaomi’s configuration might not compete directly with the latest flagship processors, it might offer solid performance for a sub-flagship phone.

Seems like a relatively solid initial attempt. Not to mention that they has massive governmental and social support (I could see an in-house SoC resonating well with the Chinese public).
