Recently shared CPU sales stats give us a good idea of what processors people are buying. The latest report is now here, courtesy of TechEpiphany, covering CPU retail sales on Amazon US during July 2026, and it shows that AMD continues to dominate the market – unsurprisingly. However, strong sales of older-gen AM4 show just how relevant the platform remains.

AMD sold 31,950 CPUs during the month of July, giving it an 86.2% share of total sales. Intel, meanwhile, sold 5,100 units for a 13.8% share. In terms of revenue, AMD generated around $9.12 million, compared to Intel’s roughly $1.65 million.

One of the most interesting parts of the report is how close AM4 remains to AM5. AM5 was responsible for 18,850 units, or 50.9% of all CPUs sold. AM4 followed with 13,100 units, giving the older platform a 35.4% share. That is a notable result for a platform that has been around for years. The continued popularity of AM4 is also helped by affordable Ryzen processors and the availability of older X3D chips.

The Ryzen 7 5800X3D, which was re-released with a special anniversary edition towards the end of June, appears to have played a particularly important role in July. The processor sold 3,050 units, accounting for 8.2% of all CPUs in the report. This puts it ahead of most newer processors and makes it the third-best-selling individual CPU overall. The Ryzen 5 5500 was actually the best-selling CPU, with 5,050 units sold, while the Ryzen 7 9800X3D came very close with 5,000 units.

X3D processors remain extremely popular

AMD’s X3D lineup also dominated the upper end of the sales chart. Zen 5 X3D processors accounted for 7,700 units, while Zen 4 X3D and Zen 3 X3D sold 3,400 and 3,050 units, respectively. Combined, that gives the three X3D generations 14,150 units, showing just how popular AMD’s gaming-focused processors remain.

Intel’s best result came from the Core i9-14900K, which sold 600 units. Several other Intel processors reached 500 units, including the Core Ultra 9 285K and Core Ultra 7 270K Plus.

Overall, the July numbers show that AMD’s newer AM5 platform is clearly ahead, but AM4 is still surprisingly strong. The Ryzen 7 5800X3D’s return appears to have given the older platform another boost, showing that there is still plenty of demand for upgrading AM4 systems without moving to an entirely new platform. It actually went out of stock at one point, before quickly coming back.
