could someone ELi5 the backside power delivery please ?
there is a good youtube video that explains it https://www.youtube.com/watch?v=hyZlQY2xmWQ

#12>1.6nm Gotta love how we now have fractions of a near meaningless metric.
Why is it meaningless?

#13Sounds like a response to Intel's 18A process [0], which is also coming in 2026. [0] https://www.tomshardware.com/tech-industry/manufacturing/int...
This is a response to something that’s coming in 2 years? Incredible how far ahead they are

An article on the topic though about Intel: https://spectrum.ieee.org/backside-power-delivery
So, if I understood that correctly, "frontside" actually is the top side, and "backside" is actually the bottom side. They're delivering power from the bottom (substrate) side, and connecting the data on the top side.

https://www.imec-int.com/en/articles/how-power-chips-backsid... has some explanation that's a bit beyond ELI5, but they have 2 pictures: frontside: https://www.imec-int.com/_next/image?url=%2Fsites%2Fdefault%... backside: https://www.imec-int.com/_next/image?url=%2Fsites%2Fdefault%... Another graphic samsung used: https://www.thelec.net/news/photo/202210/4238_4577_1152.jpg From https://www.tomshardware.com/pc-compone…
the pics go to 404

#18Earlier quoted context omitted.
Why is it meaningless?
Because it's not measuring anything, except the tech generation. It conveys about as much information as "iPhone 14".
It's at least more easily understandable (lower is newer) than the average tech product naming scheme, especially those by Microsoft.

process/node "size" has, for some time now, been divorced from any actual physical feature on or of the chip/transistor itself. See the second paragraph of: https://en.wikipedia.org/wiki/2_nm_process for additional details

Number represents transistor density. 2nm has ~twice the density of 4nm. If you ignore nm as unit of distance it makes sense.
