On February 10, the latest data released by market research firm Mercury Research showed that Intel's share of the server chip market declined in the fourth quarter of last year, but it regained some market share in the personal computer chip market.

Now Intel is trying to restore the company's edge in processor technology. Intel's share of the lucrative server chip market fell in the fourth quarter of last year, ceding more ground to AMD, and fortunately regained some share in the PC chip market.

According to data released by Mercury Research, AMD's share of the entire chip market reached 25.6% during the same period, a record high, including custom chips for game consoles and chips for the Internet of Things. This figure surpasses AMD's all-time high of 25.3% set in 2006.

Intel still holds the majority of the overall chip market, but no longer has the technological advantage it once had. This has prompted many customers to look for alternatives such as AMD chips or self-designed chips. Intel Chief Executive Pat Gelsinger has promised to regain the edge with new products that outperform longtime rivals.

The PC chip market has been booming for the past two years, which is good news for both Intel and AMD. Mercury Research found that the PC chip market will soar 11% in revenue in 2021 to $74 billion. In addition, the market size of ARM-based chips is also growing, with shipments of the entire PC chip industry reaching 500 million in 2021.

AMD dominates the gaming console chip market. AMD also made a profit, thanks to strong demand for game consoles from Sony and Microsoft.

Intel once controlled more than 99 percent of the server chip market. However, according to Mercury Research data, AMD's share of the server chip market rose to 10.7% in the fourth quarter of last year, up 3.6 percentage points from the same period last year.

During the same period, Intel's share of the desktop computer chip market rose to 83.8%, and its share of the notebook computer chip market was 78.4%.

ARM-based chips used to account for only a small portion of the PC chip market. The market share of such products is growing as Apple's Mac product line shifts across the board to ARM-based chips. In the fourth quarter of last year, the market share of ARM-based chips reached 9.5%, almost three times that of the same period last year.
