In fact, the overall appearance size of the 90 nm process chip is almost the same as the overall appearance of the current 7 nm and 14 nm process chip.
The difference is the number of components arranged on the chip, for example, the 90 nanometer process chip can be photoengraved on 1 billion components, then the 7 nanometer process chip may be arranged on 5 billion components, a very simple problem, then for sure, the 7 nanometer process chip is much more powerful, Because there are many more components on the chip of the 7-nanometer process process, the design is more perfect, more reasonable, and the function is more powerful.
90nm and 14nm refer to the size of the chip manufacturing process. The 90-nanometer process is older than the 14-nanometer process, meaning it has lower transistor density and higher power consumption. The 14nm process is more advanced, with higher transistor density and lower power consumption. This means that 14nm chips can deliver higher performance and efficiency while generating less heat.
As a result, the 14nm process chip is more suitable for high-performance computing and mobile devices, while the 90nm process chip is gradually phased out.
