Does China have CPUs? What are the CPU manufacturers?

China has its own production of CPUs: Loongson.

Loongson was successfully developed on September 29, 2002, the English name of Loongson is godson, and the homophonic nickname in Chinese is "enough to win". by the Institute of Computing Technology, Chinese Academy of Sciences.

Authorized by Beijing Shenzhou Loongson Integrated Circuit Design Co., Ltd., the early batch samples are currently by TSMC in Taiwan.

Production There are currently 2 generations produced: Loongson No. 1 and Loongson No. 2.

1. Loongson No. 1:

Loongson No. 1 CPU IP core.

It is a 32-bit processor core that takes into account the characteristics of both general-purpose and embedded CPUs, adopts MIPS III-like instruction set, and has a seven-stage pipeline, a 32-bit integer unit and a 64-bit floating-point unit. Loongson One CPU IP core is highly flexible and configurable, which is convenient for integrating various standard interfaces. Figure 1 shows the configurable structure of Loongson's CPU IP-core, where the dotted line indicates that users can choose the configuration according to their own needs, so as to customize the most suitable processor structure for the user's application.

2. Loongson No. 2:

Loongson-2 CPU adopts an advanced four-transmitter superscalar super-flow structure, on-chip first-level instructions and data cache.

64KB each, up to 8MB of off-chip L2 cacheThe maximum frequency is 500MHz, and the power consumption is 3-5 watts, which is far lower than that of similar foreign chips, and the measured performance of its Spec CPU2000 test program is VIA.

2-3 times the processor, has reached the level of medium pentium4.

Chips are not enough technology for the time being, and they have to be imported from abroad.

China has ** processors, and there is more than one, at least 30 models, you can search for this, such as Hisense, Haier, Changhong, all of which produce CPUs;

At present, the first countries in the world with CPU are the United States, Japan, Russia, China, and other countries may have but are not famous;

1. Intel.

Intel is the big brother of CPU production, it has a market share of about 80%, and the CPU produced by Intel has become the de facto x86CPU technical specification and standard, and the latest Core 2 has become the first choice for CPUs.

2. AMD.

In addition to Intel, the most powerful challenge is AMD. AMD specializes in designing and manufacturing innovative microprocessors (CPUs, GPUs, APUs, motherboard chipsets, TV card chips, etc.), flash memory and low-power processor solutions for the computer, communications and consumer electronics industries, providing standards-based, customer-centric solutions for technology users, from enterprises and institutions to individual consumers.

AMD is currently the only semiconductor company in the industry that can provide high-performance CPU, high-performance discrete graphics GPU, motherboard chipset, in order to clarify its advantages, AMD proposed a new logo of the 3A platform, in the notebook field with the "AMD Vision" logo means that the computer adopts the 3A build scheme, AMD has more than 70% of the revenue from the international market, is a real multinational company.

3、cyrix

Once the world's third-largest CPU manufacturer, it is now being acquired by Via and AMD respectively.

4. Quanmeida Nexgen IDT Company.

The former glory has gradually withdrawn from the market due to the competition between AMD and Intel.

5. IBM.

IBM, an international business machinery company, has its own chip production line, mainly producing power processors for servers.

6. Domestic Loongson.

Godson, nicknamed Gouyu, is a general-purpose processor with independent intellectual property rights owned by the state, and currently has 2 generations of products. The latest Loongson 2F has caught up with the level of Intel's mid-range P4.

7. VIA China.

VIA, a Taiwanese motherboard chipset manufacturer, has acquired the aforementioned CPU divisions of Cyrix and IDT, and launched its own CPU, which can be compared with Intel's economical CPUs, with a power consumption of only 1W, and is struggling to survive under the dual pressure of Intel and AMD.

Domestic CPUs include Huawei Kunpeng, Feiteng CPU, Haiguang CPU, Loongson, Zhaoxin, and Shenwei.

Among them, Huawei Kunpeng and Feiteng CPUs use ARM architecture, Loongson uses MIPS architecture, Zhaoxin and Haiguang CPUs use X86 architecture, and Shenwei uses Alpha architecture.

Let's start with the Kunpeng and Feiteng CPUs that use the ARM architecture, because they use the ARM architecture, so they can't install Windows, and the reason for the ARM architecture is not suitable for personal PCs, and it is currently mainly used for servers, and to a certain extent, it can only partially replace Intel's server chips.

Let's talk about Loongson, Loongson uses MIPS architecture, and it is impossible to install Windows, and the latest Loongson chip 3A5000 series, its level can only be roughly compared with the i3 series level of Intel's desktop chips 3 years ago.

Therefore, Loongson wants to replace Intel, in the field of personal CPU, it is also a little difficult, mostly used in industrial control, as well as some education, administration, etc., where performance and ecological requirements are not high, but there are high requirements for safety, autonomy and controllability.

Let's talk about Shenwei, Shenwei is mainly used for supercomputers, such as Sunway Taihu Light, which once won the title of the world's first supercomputer, and its performance is currently ranked 4th in the world.

The same Shenwei is also used for servers, but because it is also an alpha architecture, it cannot be installed with Windows, and it is difficult to be used in the field of personal PCs, and can only partially replace Intel's server chips and supercomputing chips.

Finally, let's talk about Haiguang CPU and Zhaoxin, these two CPUs use x86 architecture, the biggest advantage is that Windows can be installed, to meet everyone's requirements for Windows ecology, and it is more suitable for individual consumer PC products.

However, Haiguang CPU is mainly used for servers, and Zhaoxin can be used for personal PCs, but in terms of performance, compared with Intel, it is basically a gap of about 3-5 years, and mainstream desktops and notebooks are still quite few.

1. Intel: A company in the United States mainly to develop CPU processors, is the world's largest manufacturer of personal computer parts and CPUs, it was founded in 1968, and has a long history of innovation and market leadership.
