After a wave of sales boom, it is expected that the personal computer market will cool significantly this year. This makes the competition between Intel and amd more intense: AMD needs to continue to seize more market share, but Intel can no longer lose its private plot < p > the competition between Intel and AMD in the personal computer market can be traced back to decades ago, but the competition between the two sides really began to recover in 2018. At that time, amd began to sell new processors OEM by TSMC's most advanced manufacturing technology, while intel was still trying to improve its own production technology. This makes amd chips have certain advantages over Intel chips. According to the data of mercury research, a Market Research Institute, amd accounted for about 21% of the total sales of personal computer chips in the world in the third quarter of 2021, more than double the market share of 8% four years ago < p > figure: in the past two years, AMD and Intel have benefited from the hot PC market, but the market is expected to cool significantly this year < / P > < p > although investors pay more attention to the competition between the two companies in the data center chip market, the PC market is still the main source of revenue for the two companies. As the growth of PC sales slows down, the competition between the two companies may become more intense < p > IDC, a market research company, estimates that PC shipments will increase by nearly 12% to 337.6 million units in 2021, compared with 13% in the previous year. However, IDC expects that this year's PC sales will be the same as last year, with an increase of only 1% in 2023 < p > last week, Intel and AMD both promoted the upcoming PC chip at this year's international consumer electronics show. The latest products are mainly aimed at laptops, which account for about three-quarters of the PC market. Intel released the first batch of notebook chips manufactured by Intel 7, while AMD's Raptor chip will adopt TSMC's 6-nm process. Analysts have different views on which chip has a better prospect. Mark lipacis, an analyst at Jefferies, an investment bank, expects AMD to continue to capture market share from Intel, while Pierre ferragu of new street research, a research institution, expects Intel's new products to help it "restore competitiveness" < p > neither company is willing to be behind others. In the past 12 months, investors have pushed AMD's share price up 39%, surpassing many other chip manufacturers. Analysts predict that after soaring 65% in 2021, AMD's revenue will continue to achieve double-digit growth in the next two years. On the other hand, Intel is eager to prevent the loss of market share. The company needs to maintain business and cash flow and constantly narrow the gap with TSMC in manufacturing technology < p > but another potential problem faced by the two companies is that due to the success of the new Mac equipped with Apple's own chip, the chip based on AMD architecture may get more attention. Qualcomm announced at the international consumer electronics show that more than 200 enterprise customers are testing or deploying the company's Xiaolong chip based on ARM architecture on Microsoft Windows devices. Chris CaSO of Raymond James, an investment bank, said that "PC manufacturers need to make a strong response to the new M1 based MAC," but the market share of arm architecture chips such as Xiaolong will be at the cost of seizing the share of X86 chips produced by Intel and AMD < p > one thing is certain anyway. Even if growth slows, the PC market will be exciting this year. (Chen Chen) < / P > < p >
