The AMD Ryzen 9 7900 is the objective winner of this comparison, securing victory across seven of the thirteen evaluated specifications. Its most significant technical advantage is its L3 cache, which is 220% larger than that found in the Intel Core Ultra 5 225. This substantial memory capacity provides the Ryzen 9 7900 with a clear lead in overall hardware specifications, establishing it as the more robust option for users prioritizing raw cache performance in their computing tasks.

Users who require superior cache capacity for intensive processing should choose the AMD Ryzen 9 7900. Conversely, the Intel Core Ultra 5 225 is the better selection for those who prioritize artificial intelligence workloads, as it offers a 100% advantage in NPU performance. By identifying whether your primary workflow relies on the expanded cache of the Ryzen or the specialized neural processing capabilities of the Core Ultra, you can select the component that best aligns with your specific requirements.
