The Mi 14 does not yet have a 3nm chip.
The mobile phone chips currently on the market are mainly manufactured using 7nm, 5nm or even 3nm processes. However, Xiaomi 14, as a mobile phone product, has not yet publicly announced the use of 3nm chips. However, with the continuous progress of science and technology, there may be more advanced chip technology applied in the field of mobile phones in the future, which may also include 3nm chips.
With the continuous upgrading of the chip process, the performance and power management of mobile phones are expected to be further improved. Therefore, although the current Mi 14 has not been configured with a 3nm chip, future mobile phone products may use more advanced chip technology to improve performance.
