Just a reminder for anyone that thinks 3nm chips means the transistors themselves are only 3nm, they are bigger than that. 3nm is the marketing name for the fab process they are using.
Close, except it's not a marketing term. It's part of a published IEEE standard.
The actual gate pitch and metal pitch vary by manufacturer and process type.
From Wikipedia:
And the number keeps going down because... That's good marketing. IEEE rebranded 802.11ax as wifi 6 because... Marketing. They can do it too.
Minor correction: The standard is IEEE, but it was developed by the WiFi Alliance (who make their money by certifying devices as meeting the WiFi 6 standard). It's a pretty fair marketing strategy though. Normal users aren't going to notice 802.11ac vs 802.11ax
Especially since there are tons of specs that arent direct wifi upgrades in that same convention. I.e. 802.11ah for long range or ap for WiGig 802.11ad or confused with 802.1ax the Ethernet link aggregation standard.
Imagine trying to explain that in the store to the person that calls the wireless access point "the Internet".
