So what are the alternatives? Based on current information it seems that there are no domestic product in China that are comparable to these mainstream CPUs.
- logicchains 3y agohttps://www.tomshardware.com/news/loongson-launches-3a6000-cpu-matches-14600k-ipc https://www.tomshardware.com/news/loongson-launches-3a6000-c... they have this, which is apparently comparable to an Intel Core i3, which is probably good enough for most government work.
- not_your_vase 3y agoWell, the hardware, yes. But you are expected to compile your own software... Windows doesn't exist on Longsoon (AFAIK), and no notable distro have ready made image, nor package repository for this arch (not in the west at least. Are there such in China?). You can make it work with not a lot of effort of course, but I wonder if this is really what government folks do in their lunch break.
- yorwba 3y agoUOS reportedly supports Loongson as of 2019 https://cntechpost.com/2019/12/16/china-made-operating-system-uos-adapted-to-popular-software-first-step-to-replace-windows/ https://cntechpost.com/2019/12/16/china-made-operating-syste... Though I found this post from last month https://bbs.chinauos.com/phone/zh/post/17586 https://bbs.chinauos.com/phone/zh/post/17586 where someone complains that UOS isn't updating to Loongson ABI2.0 quickly enough.
- xcv123 3y agoThe Chinese government uses Kylin https://en.wikipedia.org/wiki/Kylin_(operating_system) https://en.wikipedia.org/wiki/Kylin_(operating_system) https://en.wikipedia.org/wiki/Ubuntu_Kylin https://en.wikipedia.org/wiki/Ubuntu_Kylin
- yencabulator 3y agoWikipedia says Loongson is used as the MIPS target of both Debian's and Go's continuous integration systems. https://en.wikipedia.org/wiki/Loongson#Operating_systems https://en.wikipedia.org/wiki/Loongson#Operating_systems
- dist-epoch 3y agoCurrent Chinese CPUs have half the performance of current Intel/AMD ones. That's pretty good, especially for office work.
- retrocryptid 3y agoI was sort of expecting at least one RISC V CPU to be on the list, but I guess we're still several years out from competing w/ Intel or ARM designs. And there's significant investment in MIPS toolchains, so maybe RV64 isn't quite ready for prime time in China?
- topspin 3y agoAlibaba Group is promising server grade RISC-V this year: https://news.ycombinator.com/item?id=39776337 https://news.ycombinator.com/item?id=39776337
- retrocryptid 3y agoWhich is why it's weird the CCP is offering no regulatory love to a CPU developed and fabbed in mainland China.
- topspin 3y agoI don't assume the left and right hands are coordinated: Alibaba only announced that a few days ago, and the CPU isn't actually available yet.
- neurostimulant 3y agoThey went hard with ARM, while developing RISC on the side. So perhaps something like this: https://www.tomshardware.com/pc-components/motherboards/first-gaming-pc-motherboard-made-entirely-with-china-tech-comes-with-integrated-homegrown-cpu-dollar700-buys-the-claimed-worlds-first-totally-china-made-board https://www.tomshardware.com/pc-components/motherboards/firs...
- blackoil 3y agoHuawei ARM chips were pretty good. Now that they have 7nm out, a ARM Linux PC seems feasible.
- alephnerd 3y agoIt needs to be fabricated by TSMC. Domestic fabrication capabilities haven't caught up yet and are currently at the same level as Taiwan, SK, and the US around 2014.
- blackoil 3y ago7nm chips are fabricated in China by SMIC. It is used in latest Huawei 5G phones. They may also be able to make 5nm in near future. Beyond that I don't know.
- throwaway2990 3y agoThe Huawei ARM chips are progression. They are not good. They are several years behind in performance.
- riku_iki 3y agoIs several years behind that large gap? I think most apps/infra are fine to run on 10yo hardware
- throwaway2990 3y ago6 or 7. Fine for consumers.
- coliveira 3y agoFrom observation of the Chinese government, I'm pretty sure they already have an alternative to these Intel CPUs. They're just creating the legal framework to require their use.
- bdd8f1df777b 3y agoOffice computers do not need high end CPUs. In fact, I know that several places have so old computers (with Intel chips) that they are probably slower than modern day Chinese processors.
