The AMD Ryzen 5 5600G is the objective winner of this comparison, securing a lead in nine out of fourteen measured specifications. Its most significant technical advantage is its L2 cache, which is 100% better than that of the Intel Core i7-8700K. This substantial cache capacity provides the primary performance edge for the AMD Ryzen 5 5600G, establishing it as the superior choice across the majority of the evaluated hardware metrics.

Users prioritizing overall architectural efficiency and the benefits of a larger L2 cache should select the AMD Ryzen 5 5600G for their build. Conversely, the Intel Core i7-8700K remains a viable option for those who specifically require a higher boost clock, as it maintains a 7% advantage in that single category. Choose the former for broader spec superiority or the latter if your specific workload relies heavily on the higher frequency provided by the Intel processor.
