This is the official announcement post, AnandTech's article is much better but it links to the Qualcomm post so thought that would be the main link. Pretty much confirms it's a cut down version of the 8s Gen 3 released a few days back. The OnePlus Ace 3V already ships with this chip in China.
Wasn't expecting an anandtech article. Been a very long time since they stopped phone reviews and in-depth mobile Soc deep dives. Still, wish for them to start again someday.
