The AMD Ryzen 9 9900X and the Intel Core Ultra 7 265 are evenly matched, as both processors secure an equal number of victories across the evaluated specifications. The most significant differentiator for the AMD Ryzen 9 9900X is its L3 cache, which provides a 113% advantage over the competition. Conversely, the Intel Core Ultra 7 265 holds a substantial lead in memory architecture, boasting an L2 cache that is 200% larger than that of its counterpart.

Users prioritizing the specific benefits of a larger L3 cache should select the AMD Ryzen 9 9900X for their build. Those who require the increased L2 cache capacity provided by the Intel Core Ultra 7 265 should opt for that processor instead. Because both components demonstrate a balanced set of strengths, the final choice depends entirely on which cache configuration better aligns with the specific technical requirements of your intended workload.
