The Intel Core Ultra 5 235 is the objective winner of this comparison, securing more individual specification victories than its competitor. While the AMD Ryzen 9 9900X holds a significant lead in memory architecture, the most impactful advantage belongs to the Intel Core Ultra 5 235, which features an L2 cache that is 117% better than the alternative. This superior cache configuration provides the primary technical edge for the winning component in this head-to-head evaluation.

Users prioritizing the specific benefits of an expanded L2 cache should select the Intel Core Ultra 5 235 for their build. Conversely, those who require the substantial 167% advantage in L3 cache capacity provided by the AMD Ryzen 9 9900X should opt for that processor instead. Your final decision should depend entirely on whether your workload benefits more from the superior L2 cache architecture of the Intel model or the L3 cache capacity of the AMD unit.
