1. Intel Corporation
Intel is the big brother in producing CPUs. It occupies about 80% of the market share. The CPUs produced by Intel have become the de facto x86 CPU technical specifications and standards. , the latest Core 2 has become the first choice for CPU.
2. AMD
In addition to Intel, the most powerful challenger is AMD. AMD specializes in designing and manufacturing a variety of innovative microprocessors (CPU, GPU, APU, motherboard chipsets, TV card chips, etc.), flash memory and low-power processor solutions for the computer, communications and consumer electronics industries. AMD is committed to Technology users—from businesses and government agencies to individual consumers—deliver standards-based, customer-focused solutions.
AMD is currently the only semiconductor company in the industry that can provide three major components: high-performance CPU, high-performance independent graphics GPU, and motherboard chipset. In order to clarify its advantages, AMD proposed a new logo for the 3A platform, which is used in notebook computers. If the field has the "AMD VISION" mark, it means that the computer uses a 3A construction solution. More than 70% of AMD's revenue comes from the international market, and it is a truly multinational company.
3. Cyrix
The once popular third-largest CPU manufacturer in the world has now been acquired by VIA and AMD respectively for its production lines and technology.
4. Metameta·NexGen·IDT Company
The once glorious company has gradually withdrawn from the market due to competition between AMD and Intel.
5. IBM
The international business machine company IBM has its own chip production line, mainly producing POWER processors for servers.
6. Domestic GodSon
GodSon, nicknamed Gou Sheng, is a state-owned universal processor with independent intellectual property rights. It currently has 2 generations of products. The latest Loongson 2F has caught up with the level of Intel mid-range P4.
7. VIA China
VIA is a motherboard chipset manufacturer in Taiwan. It acquired the CPU departments of the aforementioned Cyrix and IDT, and launched its own CPU with performance comparable to Intel Compared with other economical CPUs, the power consumption is only 1W, which makes it difficult to survive under the dual pressure of Intel and AMD.

CPU manufacturing
(1) The micron of the CPU manufacturing process refers to the distance between the circuits in the IC. The trend in manufacturing processes is towards higher density. Higher-density IC circuit designs mean that ICs of the same size can have circuit designs with higher density and more complex functions. The main ones are 180nm, 130nm, 90nm, 65nm, 45nm and 22nm.
(2) Intel has released the 32nm Core i3/Corei5/Corei7 series in 2010 and the 22nm Core i3/i5/i7 series in April 2012. And there are already plans for 14nm products (according to news reports, 14nm will be launched in notebook processors in the second half of 2013.).
(3) AMD stated that its products will directly skip the 32nm process (a few 32nm products will be produced in the third quarter of 2010, such as Orochi and Llano) and 28nm products will be released in mid-to-early 2011 ( APU).
(4) Trinity APU was officially released on October 2, 2012. The process is still 32nm, and the 28nm process code Kaveri has been repeatedly postponed. The 28nm Apu launched in 2013 was only a low-end processor for tablets and notebooks, codenamed Kabini.
