The AMD Ryzen 7 8700G is the objective winner of this comparison, securing victory in eight of the fourteen measured specifications. While the AMD Ryzen 7 3800X maintains a significant lead in memory architecture, the primary advantage of the newer model is its L2 cache, which is 100% better than that of its predecessor. This substantial improvement in cache capacity serves as the most impactful differentiator between the two processors.

Users prioritizing the latest architectural improvements should select the AMD Ryzen 7 8700G to benefit from its superior L2 cache capacity. Conversely, the AMD Ryzen 7 3800X remains the appropriate choice for specific workloads that rely heavily on a larger L3 cache, where it offers a 100% advantage over the newer unit. Your final decision should depend on whether your specific computing tasks are better served by the increased L2 cache or the expanded L3 cache.
