The AMD Ryzen 5 8600G is the objective winner of this comparison, securing a lead in twelve out of fourteen measured specifications. Its most significant technical advantage is the L2 cache, which is 300% larger than that found in the Intel Core i7-8700K. This substantial improvement in cache capacity serves as the primary differentiator between the two processors, establishing the former as the superior choice based on the provided hardware metrics.

Users should select the AMD Ryzen 5 8600G if they prioritize modern architecture and the significant cache capacity advantage it offers over the competition. Conversely, there is no objective spec-based justification for choosing the Intel Core i7-8700K, as it failed to outperform the newer processor in any of the fourteen categories evaluated. The AMD Ryzen 5 8600G is the clear recommendation for those seeking the most capable hardware based on these specific technical data points.
