The Vivo S15 Pro has launched as the latest Dimensity 8100-powered smartphone with an additional discrete graphics co-processor; however, the base S15 might steal some attention for itself with a Snapdragon 870 platform with "enhancements" exclusive to its OEM. Then again, the Pro model also has the same customized 50MP main shooter as the X70 Pro. Both phones have launched with Android 12 out of the box and start at about US$400 in China.
