The takeaway: AMD's domination in the desktop CPU market has been so remarkable that all 10 top-selling processors on Amazon throughout 2025 were from Team Red. Now, though, two Intel processors have secured a spot on the top-10 list for the first time in over a year.
Intel's Core Ultra 7 270K Plus and Core i7-14700K rank #6 and #9, respectively, surrounded by an array of Ryzen chips spanning multiple generations. Both are mid-range parts, priced at $255 and $312, respectively. The 270K Plus belongs to Intel's Arrow Lake Refresh series, while the 14700K comes from the Raptor Lake Refresh lineup.
The rest of the CPUs on the list are from Ryzen 9000, 7000, and 5000 series, with the Ryzen 7 9800X3D leading the pack.
The Ryzen 5 5500 is the top pick for budget-minded builders, landing at #2 ahead of pricier options like the Ryzen 5 9600X, Ryzen 7 5800X3D, and Ryzen 7 7800X3D, which came in at #3, #4, and #5, respectively.
The Ryzen 9 9950X3D and Ryzen 5 7600X took #7 and #8, with the Ryzen 5 5600X rounding out the top 10. The next ten spots are also mostly AMD's, with just two entries from Team Blue against eight from Team Red. Still, 20% representation in the top-20 list marks a notable improvement for a company that's been struggling to match its former glory.
AMD pushed Intel out of Amazon's best-selling CPU list back in November 2024, after Team Blue's Arrow Lake "Core Ultra 200" desktop launch fumbled spectacularly. The Ryzen 7 5700X was that month's best-seller, while the highest-ranking Intel chip, the Core i5-13600KF, sat at #12.
The main reason the two Intel chips have clawed their way back into the top-10 this month is insane DDR5 memory prices that are pushing more buyers to upgrade their existing DDR4 systems rather than splurge on a new platform. That dynamic is boosting Intel's Core i9-14900K and Core i7-14700K, both of which support DDR4, while AMD's 9850X3D, 9950X, and 9900X have slipped down the list because they're DDR5-only.
