Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.

Rules:

-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Huawei and SMIC quietly rolled out a new Kirin 9000C processor.

Chinese foundry SMIC may have broken the 5nm process barrier, as evidenced by a new Huawei laptop listed with an advanced chip with 5nm manufacturing tech — a feat previously thought impossible due to U.S sanctions.

I just read an article about how the only reason they got to 7nm was because they were abusing their less advanced methods by being willing to make a ton of faulty chips for every good one, and that it was incredibly inefficient and only feasible because of STATE INTERVENTION which is a free-market cheat code. Basically the human-wave attack propaganda but for microprocessors, lol.

Seems like they figured some things out on their own.

They can’t imagine a mode of production centered on actually producing things instead of just making money.

So… research and development?

Complaining that chemists don't make a new chemical perfectly on the first try

[–] Hexbollah@hexbear.net 46 points 11 months ago (1 children)

You always have low yield when developing new processes. You can't make a 7nm process by just running 14nm at high throughput/low yield. This is just R&D and process development.

[–] StellarTabi@hexbear.net 36 points 11 months ago

The fact they didn't do it perfectly and better on their first try is because their ideology told them not to.

lol. everyone knows that US processor production is lossy too. They just turn off the buggy sectors and sell it as an i5 instead of an i7 or whatever.

[–] TheCaconym@hexbear.net 33 points 11 months ago

Exactly right; IIRC just how many of the produced chips are actually functional is systematically kept secret by manufacturers, too, but there are a lot of duds.

STATE INTERVENTION ... is a free-market cheat code

They're speedrunning chip development by using exploits the capitalists didn't intend. Sure, this looks impressive, but I only respect glitchless runs
