The Mi 11 uses a Qualcomm Snapdragon 888 chip with a 5-nanometer process, which cannot be replaced with a Tianguet chip. Qualcomm Snapdragon chip and Mediatek Tianguet chip are completely different chips manufactured by two companies, the design of the two is different, the pin circuit is completely different, can not be compatible with each other to replace. Each company's chip design ideas are different, and the mobile phone motherboard is also designed and adjusted for each chip, so the Snapdragon chip of Mi 11 can not be replaced by the Tianguet series chip.
