A listing on the Giztop web store (now removed) revealed the full specifications of the OnePlus 8, OnePlus 8 Pro, and OnePlus 8 Lite. While the listing should be taken with a grain of salt, the specs coincide with prior rumors and leaks. Unsurprisingly, the OnePlus 8 and OnePlus 8 Pro will be powered by the Qualcomm Snapdragon 865. However, the OnePlus 8 Lite will opt for the MediaTek MTK Dimensity 1000. Other specifications (listed below) are decidedly flagship-level.
