The AMD Ryzen 5 8500G is the objective winner of this comparison, securing a lead in ten out of fourteen measured specifications. Its most significant technical advantage is the L2 Cache, which is 300% better than that of the Intel Core i7-8700K. While the Intel Core i7-8700K maintains a 6% advantage in base clock speed, it only outperforms the AMD Ryzen 5 8500G in a single category, making the latter the superior choice based on the provided data.

Users prioritizing modern architecture and the substantial L2 Cache advantage should select the AMD Ryzen 5 8500G for their build. Conversely, the Intel Core i7-8700K remains a viable option for those who specifically require the 6% higher base clock speed provided by that processor. Choosing between these two components depends entirely on whether your specific needs are better served by the cache capacity of the AMD option or the base clock frequency of the Intel alternative.
