The AMD Ryzen 7 3800X is the objective winner of this comparison, securing a lead in nine out of fourteen measured specifications. Its most significant technical advantage is the L3 Cache, which is 167% larger than that of the Intel Core i7-8700K. This substantial memory capacity provides the primary performance edge for the Ryzen processor across the majority of the evaluated categories, establishing it as the more capable component based on the provided data.

Users prioritizing high-capacity cache for data-heavy tasks should select the AMD Ryzen 7 3800X for its superior architectural specifications. Conversely, the Intel Core i7-8700K remains a viable alternative for those who specifically require the 33% advantage in Max Turbo Power. Choosing between these two processors depends on whether your specific workload benefits more from the expanded cache offered by the Ryzen or the higher power ceiling provided by the Intel unit.
