On December 24, the "Chinese Academy of Sciences Science and Technology Innovation Highlights Screening" activity page shows that the LoongArch instruction set based on the independent architecture LoongArch instruction set of LoongArch server CPU research and development has been completed.
It is reported that the chip has 16 LA464 large cores, 32MB cache, the main frequency of 2.1 ~ 2.3GHz, single-chip double precision floating-point peak operation speed of more than 0.5TFLOPS, the comprehensive performance is not behind the mainstream server CPU of the current market, will be used for cloud computing or big data centers.
For a long time, the domestic CPU market, especially in the consumer-grade field, has not been easy to see the figure of domestic brand chips. With the gradual improvement of the requirements of various units for data confidentiality and process pulling, the demand for the use of domestic chips has become more prominent, and it has also provided a space for high-performance domestic CPUs to show their skills.

In fact, many years ago, the development of the semiconductor industry has received support, subsidizing chip research and development companies to catch up with the upstream, but this road China has lagged too far behind, and it is not easy to catch up. Shaking China and even the emergence of such a fraudulent enterprise as Hanxin, not only delayed the chip research and development work, but also made many people lose confidence in the semiconductor industry.
Fortunately, there are still many companies that are not afraid of difficulties to adhere to independent research and development, in addition to Loongson's self-developed architecture server CPU, Huawei has also launched the Kunpeng series of ARM architecture server CPUs before. The main reason why these companies first develop server CPUs should be that the requirements for server CPUs are not so strict, and they can be purchased in bulk in actual sales, which helps enterprises to quickly recover research and development costs.
Loongson, Huawei, etc. have also launched business-grade CPU products for PCs and notebook computers, but due to architecture, performance and compatibility issues, the experience of these chips on mainstream personal platforms such as Windows platforms still has a lot of room for improvement. Even for ordinary consumers, it cannot be said that it can completely replace the existing mid-to-high-end products.
Of course, the current difficulty is the inevitable situation encountered by Loongson, Huawei and other enterprises on the road of independent research and development, as long as they persist, there will be a day when they will see the blue sky. And all sectors of society are vigorously supporting the independent research and development of domestic CPUs, and with their help, the difficulty of self-developed CPUs will be reduced a lot.
