The AMD Ryzen 7 3800X is the objective winner of this comparison, securing more victories across the evaluated specifications. Its most significant advantage over the Intel Core i7-11700K is its L3 cache, which is 100% larger. This substantial difference in cache capacity provides the primary technical edge for the Ryzen processor in this head-to-head assessment, as it outperformed the Intel alternative in six categories while matching it in seven others.

Users prioritizing memory architecture should choose the AMD Ryzen 7 3800X to leverage its superior L3 cache capacity. Conversely, the Intel Core i7-11700K is the appropriate selection for those who specifically require a higher boost clock, as it maintains an 11% advantage in that single metric. Selecting between these two components depends entirely on whether your workload benefits more from the expanded cache of the Ryzen or the increased frequency offered by the Intel.
