This is SMIC's name code for the 7nm process
< br >
n1 technology is the internal code of SMIC. This technology is optimized on the 12nm process chip by SMIC. This optimization greatly improves the performance of the chip by a notch. Specifically, SMIC n1 is very similar in terms of power stability, the only difference is that the performance N1 has improved by about 20% over 14nm, but the market benchmark has improved by 35%. Some people in the outside world say that the optimized chip can achieve the performance of the 7 nanometer chip, which may be some exaggeration. To be precise, the performance of the optimized 14-nanometer chip can reach the performance of the 10-nanometer chip, and do not underestimate the accuracy of the 4-nanometer, which is a very big progress
Kirin chip N 1 refers to SMIC's code name for its second-generation advanced process, compared with the existing 14nm process, performance improved by 20%, power consumption reduced by 57%, logic area reduced by 63%, SoC area reduced by 55%, also known as the \"domestic version\" of 7nm chip technology.
