MediaTek is now rumored to have a new 5G Dimensity chipset ready to go. More detailed specs for this putative 1300T are now allegedly out there, including a 6 nanometer (nm) architecture and an ARM Cortex-A78 core, a combination that might easily rival Qualcomm's Snapdragon 865 SoC, if not the newer 870. It is slated to launch tomorrow (July 26, 2021).
