Corerain Technologies launches world-first commercial AI chip
Shenzhen-based startup Corerain Technologies Co Ltd launched the world's first commercial artificial intelligence chip based on streaming architecture on Tuesday.

It claims the efficiency of the Custom Artificial Intelligence Streaming Architecture (CAISA) chip is 3.9 times that of the chipmaker heavyweight NVIDIA's T4 GPU, and its chip utilization ratio can achieve 95 percent, 11.6 times of the latter, according to a third-party tester.

Comparing the two products, Niu Xinyu, who founded the technology firm in 2016, said CAISA adopts a radically different approach where the computation order is determined by the data streaming network, instead of the instruction execution order, so that the idle time is substantially minimized by cutting the waiting time for instructions.

He believes it is a novel road toward the next generation of AI computing platforms and Corerain is in the lead.

More importantly, we are the first to achieve mass production of such AI chips, he highlighted, saying CAISA has been put into the markets of automatic driving, smart cities and intelligent manufacturing.

The startup also teamed up with the world's leading IT companies, such as Intel Corp, Inspur Group and Dell, for application development of the AI chip.

If I remember correctly, Huawei is dependent on Xilinix for FPGA chips. Wondering if these can replace the American chips in Huaweis base stations.

ekhm, it's more like there's German version and Japanese version. Chinese version can be considered as developed version of German Transrapid. But whatever, it's fast and it's good that China invests money in this technology.
That’s fair enough, but I guess it depends on how we qualified tech progress, the base tech is German tech but any further developments, improvements or changes to the system should be considered Chinese, no? Forget about bias and nationalism for the moment, I am not sure how we qualify it, I mean if we go down the rabbit hole, then we would run into problems like all trains, being on rails would essentially deem them all as UK version train... it’s not a question to be discussed on this thread/forum but it’s an interesting question nonetheless.

That can be said for Fuxing as for Shinkansen, but it's just better and Chinese. No worries, maybe this could motivate Japanese to improve more the machinery. Germans should implement Maglev to it's country. WTF ? But there's no intention as it seems, so R&D by Siemens probably put on halt since there's no pragmatic reason. I'm curious about further implementation of Maglevs in China, through the paths of conventional HSR, upgrading the railway tracks to Maglev tracks
I think it would be hard for China to change all the HSR into maglev, even over time, and may not be that practical either, with normal rails if push come to shove you can still put a diesel locomotive on it and it would do the job but if you change to pure maglev, any issue with the power grid and you are done or at least the it would harder to find a temp solution. I think most likely the maglev will be a separate network of express trains for the major cities no middle stop off, like I don’t know Beijing to Shanghai, Beijing to Guangzhou or something along the lines, where the full speed of the line can be used to maximum. Or maybe even for the megacities to megacities, that China seems to want to implement like the Beijing triangle or Great Bay Area for example.

New lab to develop next-generation batteries

FUZHOU, June 25 (Xinhua) -- Contemporary Amperex Technology Co. Limited (CATL), China's largest lithium-ion battery maker, broke ground on Wednesday on a new laboratory to develop next-generation batteries. It is being constructed at its headquarters in the city of Ningde, east China's Fujian Province.

The "21C Lab," covering an area of 18 hectares, will focus on the development of next-generation electrochemical energy storage systems, and new energy conversion systems. Beyond advanced research and development on metal lithium batteries, all-solid-state batteries and sodium-ion batteries, the 21C Lab will also work on the commercial application of its technology, such as developing lithium-ion battery reliability models, and non-destructive testing technology, the company said in a press release.

About 3.3 billion yuan (466.7 million U.S. dollars) will be invested in the laboratory, which is expected to attract about 1,000 researchers within five years. The laboratory is scheduled to be partially put into operation at the end of 2021.

"The 21C Lab epitomizes our corporate philosophy of mastering basic skills and unleashing imagination. Supported by innovative mechanisms, we will commit ourselves to making further contributions to the development of new energy," said Robin Zeng, founder and chairman of CATL.

The battery giant reported a 28.6-percent year-on-year growth in net profit in 2019, but its net profit shrank by 29.14 percent in the first quarter of 2020 from a year ago, due to the COVID-19 epidemic. Enditem

Huawei received permission from UK to build $1.2 billion British research center. Nowadays, when it comes to 5G, all that the U.S. can do is to issue warnings.
The US issued a fresh warning about security risks posed by Huawei after the Chinese company was given clearance to build a £1bn new chip research and manufacturing facility in England, saying the decision put its trust in the UK at risk.

US officials directly lobbied against the plant with British politicians, but a committee of South Cambridgeshire district councillors on Thursday voted nine to one in favour of Huawei’s project which has thrust the tiny village of Sawston into the global spotlight.

hi SKYWATCHER

Some points taken from our owned SUPERSNOOP from HK thread

However, it is just a symbolic gesture anyway. Taiwan’s wages are awful. I read somewhere that they lose something like nearly 50% of college grads to China, and 80% of grad students that study outside of Taiwan never return. Really just insane numbers.

Do you have an idea if China is able to exploit the talent needed in Taiwan, I had a contrasting report that Ms TSAI had been able to halt the exodus.
