Loongson 3A40003B4000 released in Beijing, using the same 28nm process as the previous generation of products, through design optimization, to achieve a doubling of performance, Loongson adhere to independent research and development, all functional modules in the chip, including CPU.
According to the data provided by the official website of Loongson, at present, the most high-end consumer chip product is 3A4000, which is a four-core 28nm process product, the main frequency is 1820GHz, and the power consumption of 15GHz18GHz20GHz is 30W40W50W If you understand the hardware parameters of the friend will understand.
On March 31, China launched the first "Loongson" Beidou satellite on December 24, 2019, Loongson 3A40003B4000 was released in Beijing, using the same 28nm process as the previous generation of products, through design optimization, to achieve double the performance of the Loongson adhere to independent research and development, all functional modules in the chip, Including the CPU.
Compared with the previous generation of quad-core processor Loongson 3A3000, the overall measured performance of the chip has been doubled. Operating system application with Loongson 3A30son, formerly known as GODSON1) is a general-purpose CPU developed by the Institute of Computing Sciences of the Chinese Academy of Sciences, using a simple instruction set, similar to the MIPS instruction set. The first type has a speed of 266MHz and was first used in 2002.
loongson is a Loongson chip. The "Loongson One", born on August 10, 2002, is the first general high-performance microprocessor chip with independent intellectual property rights in China. "The mother of the chip" Huang Lingyi: Get rid of the Western chip monopoly, "Longson 3" stunning the world She has dedicated her life to China's chip cause.
The third type is targeted at 1GHz. Loongson (formerly GODSON1) is a general-purpose CPU developed by the Institute of Computing Sciences of the Chinese Academy of Sciences with a simple instruction set, similar to the MIPS instruction set. The first type has a speed of 266MHz and was first used in 2002. The Loongson 2 has a maximum speed of 1GHz.
Remarkably, though only optimized by design, DragonThe performance of the core 3A4000 is expected to double at the same frequency, indicating its future potential. The conference will be held at the National Convention Center, and the content is rich and diverse.
For the next generation 3A4000, which is expected to debut in early 2019, the performance is expected to improve to 80% to 90% of the i5-7200U. However, process limitations may leave it some way off from the Megacycle KX-6000. 3A4000 is expected to become the leader of domestic autonomous processors, but the gap with Intel and AMD is still obvious.
However, with the international leading level of CPCompared with the Loongson CPU, there is still a certain gap in performance. For example, the Loongson 3 series is equivalent to 30% to 40% of Inteli5-7200U in single-core performance, and the next-generation Loongson 3A4000 processor same-frequency performance will be increased from 60% and 70% of i5-7200U to 80% to 90%.
In terms of performance structure, the new generation of general purpose processor 3A4000/3B4000 adopts 28 nm technology, and through design optimization, the performance is more than twice that of the previous generation, and the main frequency reaches 8G GHz to 0G GHz. All the source code for the chip isIt is designed independently, and the security control mechanism is designed in the processor core.
Compared with the previous generation of Loongson 3A4000 processor, under certain conditions, the performance is improved by more than 50%, and the power consumption is reduced by more than 30%. In the tripartite test, the fixed-point and floating-point single-core Base scores of SPEC CPU2006 run under GCC compilation environment reach more than 26 points, and the quad-core base scores reach more than 80 points. On March 31, China launched the first Beidou satellite using the "Dragon Son". On December 24, 2019, the Dragon Son 3A40003B4000 was released in Beijing.Using the same 28nm process as the previous generation of products, through design optimization, the performance is doubled and improved, and all functional modules in the chip, including the CPU, are independently developed.
