"The angstrom or ångström is a metric unit of length equal to 10⁻¹⁰ m; that is, one ten-billionth of a metre, 0.1 nanometre, or 100 picometres. Its symbol is Å, a letter of the Swedish alphabet. The ångström is not a part of the SI system of units, but it can be considered part of the metric system in general."

It happened before in the pentium era, where processor processes were measured in micrometers until it got to single digits and started naming then in nanometers for the Core ones. Props to Anthony, maybe the one with the most knowledge in LMG

Nobody:
Picometers: rubbing hands in joy at being next in line
Angstroms: hold my beer

I am curious to see how Intel and other chip manufacturers are going to prevent electron jumping with these super small transistor gaps they have planned.

[AlexSchendel]

It's worth noting that measurements of length (nanometers and angstroms) became entirely detached from any measurement of the actual transistor. Years ago, that referred to the gate length of the transistor, but just before FinFETs became the norm (~22nm), the process node number kept shrinking while the actual gate length shrunk at a much slower rate. For example, most 14 nm processes utilize a gate length that is roughly 30 nm. Most transistor optimization these days comes from other methods such as tweaking channel strain to change the drive current of the transistor to make the transistors more power efficient or have faster switching (or both).

Wow I've never been this early, always fun to have Anthony hosting a video!

Anthony said Intel 5. So it's Intel 5 now. Take this note, Intel

[billrichards]

Oh how I love to see that smart man, entertaining me with knowledge bits. Thanks Anthony.

0:30 that ryzen 5 has 12nm transistor 3000G is ZEN+

[thejackal]

Ah, Zork. Good to see some still remember the games of my youth.

[javierortiz]

I think we need some universities or scientific colective to sit down and set the parameters for measuring transistors, I don't want to start listening about "blast processing" bs again.

[IgabodDobagi]

Ah, the memories of playing Zork on my 85 Tandy computer. Thanks for that blast of nostalgia.

would love to see a junkyard wars episode building a file server and webserver and getting internet access to the webserver only

Make a video about photonic CPU’s because I love this channel!!!

[laharlk]

cant we just use picometers instead? like when we went from 1.5um on the 286, 386, 486 to the 600nm on the pentiums and so on

A little Wikipedia citation:”The unit is named after 19th-century Swedish physicist Anders Jonas Ångström (Swedish: [ˈɔ̂ŋːstrœm]). The BIPM and NIST use the spelling ångström, including Swedish letters; but this form is rare in English texts. Some popular US dictionaries list only the spelling angstrom. The symbol should always be "Å", no matter how the unit is spelled. Nonetheless, "A" is often used in less formal contexts or typographically limited media.”

Well, we have Unicode now… Since I’m also a Scandinavian 🇳🇴, could you pleeease respect our strange letters “Å” and “ö”? Makes us feel proud… NIST also says to do so, although the Å actually is deprecated, and not an official SI unit. When Intel makes propaganda, they should check the details. CPUs are complicated to make, but obviously even worse to measure… 😅

The “Å” is pronounced like the vowel in eng. “or” or “ore”, by the way… 🥸👍

When Anthony hosts, I watch till the end. :-)

If they were actually measuring the size of the gate, the nanometer scale would be sufficient, because a silicon atom is a third of a nanometer, but in reality they measure the equivalent size of a transistor on a flat surface.

New editor? That key framing triggers my OCD

YES ANOTNOYYYY I LOVE WHEN U DO THESE VIDEOS
