The Intel Core Ultra 9 285 is the objective winner of this comparison, securing more victories across the evaluated technical specifications. While both processors offer distinct architectural strengths, the most significant advantage belongs to the Intel Core Ultra 9 285, which features an L2 cache that is 150% better than its competitor. This substantial lead in cache capacity provides the Intel chip with a clear technical edge in the overall evaluation of these two components.

Users prioritizing the specific benefits of a larger L2 cache should select the Intel Core Ultra 9 285 for their build. Conversely, those who require the unique advantages of a larger memory buffer should opt for the AMD Ryzen 9 9950X, which maintains an L3 cache that is 78% better than the Intel alternative. Your final choice should depend on whether your workload benefits more from the superior L2 capacity of the Intel chip or the L3 cache advantage of the AMD Ryzen 9 9950X.
