why this dude got banned lmao ?
edit: ia bot apparently.
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:
The term “3 nanometer” has no direct relation to any actual physical feature (such as gate length, metal pitch, or gate pitch) of the transistors. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a 3 nm node is expected to have a contacted gate pitch of 48 nanometers, and a tightest metal pitch of 24 nanometers.[12]
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.
IEEE rebranded 802.11ax as wifi 6 because… Marketing
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”.
So, the IEEE has an actual norm for marketing speak.
Which, honestly, ought to happen more often.If I’m not entirely mistaken there is still some basis to the nanometre number, it just doesn’t refer to the actual smallest feature size or gate pitch anymore. Basically in the mid-2000 Dennard scaling stopped working and ever since the nanometre numbers are “made up”. Dennard scaling was how most progress was made by just shrinking transistors. But that doesn’t mean just because Dennard scaling doesn’t work anymore there is no progress, it’s just harder to achieve. So the semiconductor manufacturers just continued naming their fabrication methods as if Dennard scaling still worked. So basically a modern “3nm” process is equivalent in some way to what would theoretically be possible if you had an actual 3nm process.
They should count up by some benchmark. If x/mm^2 doesn’t capture the improvement anymore, and they aren’t shrinking things much anymore, benchmark some common output.
It’s not necessarily about transistors/mm^2, there is also power consumption and clock frequency. Back in the mid-2000’s clock frequencies stopped just under 4GHz and then went down for a few years before going back up to way past 4GHz in the last ten years or so.
Yup that’s exactly what I’m talking about. They need a benchmark for what it can do, not the size of a part or a made up size for marketing. Or just disconnect the specs from the marketing name entirely.
Its at least somewhat based on the transistor density increase they get from other techniques right? Like “3 nm” is the equivalent transistor size they’d need to get the same transistor density using 2005 chip design.
I thought fabs are bad agains earthquakes
They are. But Taiwan is prone to earthquakes as well and seem to handle them fine
Those fabs in Taiwan, even though they look like plain boxes from the outside, are really a wonder of human ingenuity. Each machine that’s sensitive to quakes is on a vibration isolation pedestal and that pedestal is seismically braced, from what I’ve read.
Not to mention every building in Taiwan is laced with explosives in case China ever attacks…

Be me in a different life, changing a lightbulb in my Taiwanese home. Slip on the ladder and grab the light holder tearing it from the wall. The wiring breaks against the det. cord causing a neighbourhood wide chain reaction that can be seen from space.

This one will be designed to work during earthquake. Meaning that it won’t work without earthquakes
Is there anything that’s good against earthquakes?
flying type pokemon
Weak against SR, better have levitate
Godzilla?
Mr. Godzilla, i would like one RAM please 🙏
Godzilla blesses you with a large dose of radiation.
Ahhhh, not what i was looking for! 🫠 Guess that’s what i get for asking a kaiju for PC components though 😅 I’ll have to remember this for next time
