According to an expert report, AMD captures about a third of the global processor industry.

According to a research by an analyst, British chip technology firm Arm Ltd's growth in the PC market stalled in the fourth quarter of 2022, and Advanced Micro Devices Inc. AMD has taken about a third of the market for central processing units.

AMD has taken market share from Intel Corp. INTC, which still dominates the market for so-called x86 processors, which are compatible with widely used operating systems like Microsoft Corp.'s MSFT Windows. According to Mercury Research, Intel had a 68.7% market share for x86 processors in the fourth quarter compared to AMD's 31.3%, which was an increase from 28.5% a year earlier.

The analysis by Mercury Research President Dean McCarron stated that the PC chip market was experiencing its biggest decline since the 1980s and may have ever experienced in the history of the sector. Since the epidemic, when PCs and laptops were in high demand for working from home, people and businesses have scaled back their purchases because to growing inflation and uncertainties in the economy.

Regarding the analyst report, AMD opted not to respond. Arm could not be reached for comment right away.

However, the decline in PC sales has also had an impact on Apple Inc.'s AAPL Mac computer series, the main market for Arm-based PC CPUs.

Mercury claimed that Arm PC chips, led by Apple's own chips but also included Qualcomm Inc.'s most recent PC chips for Windows PCs, currently hold a 13.3% market share of the PC chips, down from 14.6% a quarter earlier but still an increase from the 10.3% share held a year before.
