They could always just take back Taiwan…

This is true, China is getting cockblocked from buying any advanced chip manufacturing machinery. Which is why they will need to produce their own machines instead. Don't expect any chips on par with AMD or Intel until you hear about Chinese home-grown chip manufacturing machines reaching parity with ASML.

Lainchan is pretty good too, but wouldn't you like to discuss things with your leftypol pals too, anon?

It's interesting that both Russia and China are jumping on the RISC-V train. I don't know if US sanctions and risk of sanctions will end up killing the US tech dominance in the global market. Just like US stopping countries from using the dollar makes more and more countries look for alternatives forms of conducting global trade.

RISC-V allows for tailoring chip design, it gets more application specific performance for any given chip, that is particularly interesting for budget application, where you can switch to a lower tier chip production with this method without loosing relevant performance. Russia and China are more "cost sensitive", that's why they are early adopters.

what about OpenPOWER

How hard will it be for China to acquire the expertise, tech and build a manufacturing base for more advanced chips to catch up and keep up with the rest of the world?

anybody know anything more about this ?

The important bottleneck in chip making is the lithography machines. The tech leader is ASML, that's a company in the Netherlands that is blocked by the US from selling to China.

(For the next paragraph smaller number = better)
China has made it's own lithography machines company and that one is called SMEE, they have machines in place for 28nm mass production at the moment, and they are working on getting mass production roll out of 14nm next year. The chip maker in Taiwan TSMC who is allowed to have ASML lithography gear is currently doing 7nm mass production and they are working on getting 3nm in to production at some time in the future.

China is behind 3 generations for the high end chips, but over100nm chips are still used in many applications. For chips that don't need that much performance they are already set. The small numbers in nm are most critical for portable devices because it means less battery drain and heat.
From the synthetic spec numbers it seems that China is catching up, how the realworld processing performance is stacking up, i don't know.

The US primary strategic goal of chip asfixiation has failed, china can self supply their strategic needs for chips. The secondary objective is commercial, they are trying to make Chinese products less competitive. That has had some effect but China is still able to source high end chips. And the US can't push too hard because China could cut the US off from TSMC. and the US is only now beginning to build out their own chip self sufficiency with new chip factories.

I guess that we should root for every side that is building out chip production because that means the chip supply gets better. This post was typed on a computer that's using 32nm chips (if i'm not mistaken)

It can be easy, just attract the talent and allow them to become part of Chinese society with minimal hurdles. People will come. But we all know nationalist countries will never work that way lmao, so likely it will take a long time and they will be outcompeted by other societies who do a better job of attracting people.

>>10269
They don't have to "attract the talent" (although they've been doing a lot of poaching engineers from Taiwan lately). They have 1.4 billion people and their math education is generally better than the Americans'.

>what about OpenPOWER
You can buy these already, it's a evolution of the type of processors that used to be in Macintosh computers.
For example a Power9 based blackbird desktop computer from raptor is the closest thing to a fully open hardware that is actually usable as a powerful PC. You have to go through a lot of hoops to set it up correctly but you also do get a lot of security benefits. Compared to RISC V this is a lot more mature and has more processing horsepower.

If you have the money and necessary technical inclination for the set up process, it comes highly recommended.

thanks for the informative post anon

Suppose a company makes OpenPOWER or RISC-V chips. Is there any way we can verify that the manufacturer actually made the chips according to the published plans? Could they still insert backdoors that we can't find?

No.
> Could they still insert backdoors that we can't find?
Yes.

>>10278
Oh ok. Should be no problem to come up with better chip designs soon then 👍

>>10350
This issue is not chip design but instead, the production of chip manufacturing machinery.

You can take the official chip plans and scramble the design, that "encrypts" the hardware level so that you need special encoded binaries for software to run, it also makes inserting a hardware backdoor impractical because the backdoor circuits would only see scrambled signals. So it's possible to design around an untrustworthy hardware maker, even if technically you can't verify the contents of a chip. You will however need to compile every software from source to install it, with a special -scrambler compiler flag.

>>10365
That sounds interesting, do you have more resources to learn about it?

>>10337
What about a microscope?
