EE Times has a long but interesting article about the process nodes that are used today, you can read it
over here. The site notes that while most SoCs now use 7nm not all 7nm is equal.
It should be noted that the above data comes from WikiChip [1]. This data actually differs slightly from the official data provided by various manufacturers and seems to be different from the data actually given by other tech research firms such as TechInsights. For example, at the node of 10nm, TSMC first gave a gate pitch of 64nm and an interconnect pitch of 42nm. TechInsights considered this data to be inaccurate after research, and they preferred these two values ??to be 66nm and 44nm respectively. The data provided by WikiChip, however, is 66nm, 42nm. Keep in mind that the sources of information on various process technologies disagree on some particulars.
