The AMD Ryzen 9 9900X and the Intel Core Ultra 5 245K result in an objective tie across the evaluated specifications. While both processors demonstrate competitive parity, the most significant differentiator for the AMD Ryzen 9 9900X is its L3 cache, which is 167% better than that of its counterpart. Conversely, the Intel Core Ultra 5 245K holds a distinct advantage in its memory architecture, featuring an L2 cache that is 117% better than the alternative.

Users prioritizing the superior L3 cache capacity provided by the AMD Ryzen 9 9900X should select that model for their build. Those who determine that the 117% advantage in L2 cache offered by the Intel Core Ultra 5 245K better suits their specific computing requirements should choose the latter. Because the overall comparison results in a tie, the decision rests entirely on whether your workload benefits more from the specific cache advantages of either component.
