The vivo X23 was expected to feature a Snapdragon 670 chipset, but a score in the Geekbench database shows a Snapdragon 710 instead (and confirms the rumored 8GB of RAM).
Theres no reason both cant be true this model (V1809A) was seen next to another model (V1809T) when both were certified with 22.5W fast chargers. So, one could be the X23 and the other the X23 Pro. Then theres the vivo V11 Pro with nearly identical looks and a Snapdragon 660.

Anyway, the vivo X23 was supposed to be unveiled yesterday, but all we got was a teaser. It did confirm some of the key specs, however 91.2% screen to body ratio and in-display fingerprint reader. Some readers also suggest there will be a 3D scanner, but thats TBD.
