Currently the smallest node size we see in smartphone processors is 7nm. These sets of chipsets are more efficient and perform better than the larger ones; the smaller they are, the more transistors they have.
Every year we see significant advancements in the chipset industry. Moore's Law suggests that every two years the number of transistors in microprocessors should double as their size decreases, so the main companies in the sector such TSMC they are forced to step up from time to time to produce better and smaller chipsets with nm architectures. The most efficient that this brand now produces are 7nm mobile platforms, but by 2025 it is expected to offer 2nm solutions.
Although there are already plans for the development of TSMC's 2nm technology, 5nm-based architecture is expected to be ready by the end of this year, which would represent a rather significant performance increase in next-generation chipsets.
In theory, 2nm chips will be able to hold 3.5 times more transistors than the best 7nm chipsets available on the market. This would result in much lower power consumption and higher working efficiency.
TSMC, on the other hand, recently revealed the 3nm chip roadmap, which is progressing as planned. The first batch of venture production is expected to start in 2021, followed by volume production in the second half of 2022. The company is investing heavily in R&D for its next future technology solutions; there is no rest.
The only major competitor for TSMC is Samsung. However, the South Korean has yet to make 5nm chips and has even delayed 3nm chipsets until 2022 due to the COVID-19 pandemic. It seems to be further behind.
