The AMD Ryzen 5 8600G is the objective winner of this comparison, securing victories in twelve out of fourteen measured categories. Its most significant technical advantage over the Intel Core i7-8700K is its L2 cache, which is 300% larger. This substantial increase in cache capacity provides the primary performance edge for the newer processor, as the older model failed to outperform the Ryzen 5 8600G in any of the evaluated specifications.

Users prioritizing modern architecture and superior cache capacity should select the AMD Ryzen 5 8600G for their build. Because the Intel Core i7-8700K did not win in any category and tied in only two, it lacks the technical advantages necessary to compete with the newer hardware. Consequently, the Ryzen 5 8600G is the clear choice for those seeking the most capable component based on these specific technical metrics.
