The AMD Ryzen 7 8700G is the objective winner of this comparison, securing victory in eight of the fourteen evaluated specifications. While the AMD Ryzen 7 3800X maintains a significant lead in memory architecture with 100% more L3 cache, the 8700G counters with a substantial advantage in its own right. The most impactful improvement offered by the 8700G is its L2 cache, which provides a 100% increase over the 3800X, representing the largest performance-related gap between these two processors.

Users who prioritize the specific benefits of a larger L2 cache should select the AMD Ryzen 7 8700G for their build. Conversely, those who require the unique advantages provided by the 100% larger L3 cache found in the AMD Ryzen 7 3800X should opt for that model instead. Choosing between these two components depends entirely on whether your specific workload benefits more from the increased L2 capacity of the newer chip or the expanded L3 cache of the older one.
