28nm chips are not enough for daily use.
Chips for daily life is the most used for mobile phones and computers, the current mainstream mobile phone chip is 5 nm, computer chip about 14 nm, this is because the data to deal with is very huge, such as large software games, high-definition video and so on very eat computing power. So 28 nm is not enough for this, but the application of chips in daily products is actually far more low-end chips than high-end chips, such as home appliances, automobiles, etc., for these 28 nm is actually enough, because these professional chip data computing requirements are relatively simple.
The 28-nanometer process of the chip is able to be satisfied with daily life use. It is only in comparison with the current chip process that the 28nm chip is backward, and it is enough to take a 28nm process processor alone.
28nm process chips such as Qualcomm Snapdragon 801 processor is a true fragrance chip, in the year at the ceiling level chip, if the performance output is not too much requirements, 28nm is now enough.
See your needs, Taobao and other big software, big games don't want to play smoothly, now 5nm are almost popular, 28nm chip is basically eliminated
