The Redmi Note 8 Pro is a recent release from this Xiaomi sub-brand that currently runs MIUI 10. However, it now seems that a major software upgrade is on the cards for this 64MP camera phone. Most of its latest listings on Geekbench 4 are associated with Android 10 rather than Android 9.0 (Pie).
These benchmark results, which are approximately 10 in number, were generated today (November 19, 2019). Most of them pertain to the 6GB variant of this phone, and list the same specs as those for the Note 8 Pro on Android Pie. They include the phone's MediaTek Helio G90T (or MT6785V/CC) processor and motherboard code name ("begonia").
Many of these new results are also among the best for the Redmi Note 8 Pro thus far. They score approximately 2560 in single-core tests and 7700 in multi-core terms. This suggests that the implied upgrade to MIUI 11 is well-optimized for these phones, at least. To date, however, there is no official word from the OEM about such a software change for this popular 2019 phone.
