The Intel Core i9-14900KS is the objective winner of this comparison, securing a lead across nine distinct specifications compared to the four won by the Intel Core i7-8700K. The most significant technical advantage held by the newer processor is its L2 Cache, which is 2033% larger than that of its counterpart. While the older chip maintains a 62% advantage in Max Turbo Power, the superior cache capacity establishes the newer model as the more advanced component.

Users requiring the highest possible cache capacity for their computing tasks should select the Intel Core i9-14900KS to leverage its substantial architectural lead. Conversely, the Intel Core i7-8700K remains a viable option for those prioritizing the specific power profile defined by its Max Turbo Power advantage. Choosing between these two processors depends entirely on whether your workload benefits more from the massive cache expansion of the newer unit or the power characteristics of the older model.
