Starts at 1999 RMB ($276/€257) for the 12 GB RAM 256 GB storage variant. There are three other variants, 12/512 for 2299 RMB ($318/€296), 16/512 for 2499 RMB($345/€322) and 16 GB/1 TB variant for 2799($387/€360) RMB. It may be available as the Poco F6 internationally. The primary sensor is a Sony LYT 600 sensor which is a 50 MP 1/1.95" sensor. They've also got rid of the 2 MP macro after keeping it for what feels like an eternity.
I'm not sure about Xiaomi's lineup even though this is great value at least in China. The Turbo series is supposed to be Redmi's performance focused flagship and is supposed to slot in between the Redmi Note series and K series. The problem is it is better than the Redmi K70E/Poco X6 Pro and arguably better than the Redmi K70 which could be sold as the Poco F6 Pro globally. The 8s Gen 3 is essentially an 8 Gen 2 with a slightly weaker GPU but with newer ARM architecture for the CPU which should lead to better efficiency.
