Investing.com -- AMD and ARM both gained market share in the microprocessor market during the third quarter of 2025, while Intel saw its position decline, according to new data released Tuesday by Mercury Research.

Total microprocessor unit shipments increased by 3.9% quarter-over-quarter in the third quarter, exceeding the typical seasonal growth of 2.4%. This stronger-than-expected performance was primarily driven by above-seasonal shipments in both server and notebook CPU segments.

Intel’s market share dropped by 157 basis points compared to the previous quarter, bringing its total microprocessor unit share to 64.2%. Meanwhile, AMD increased its position by 108 basis points to reach 22.1% of the overall microprocessor unit market.

ARM also made gains in the quarter, adding 49 basis points to its market share, which now stands at 13.7% of total microprocessor units.

The report highlights the ongoing competitive dynamics in the processor market as AMD and ARM continue to challenge Intel’s historically dominant position.
