The Intel Core i7-11700K is the objective winner of this comparison, securing victories in eight of the fourteen evaluated categories. Its most significant technical advantage is the L2 Cache, which is 167% larger than that of the alternative. This substantial increase in cache capacity provides the primary performance edge for the newer processor, establishing it as the superior option based on the total number of winning specifications across the board.

Users prioritizing modern architecture and increased cache capacity should select the Intel Core i7-11700K for their build. Conversely, the Intel Core i7-8700K remains a viable choice for those who specifically require a lower Max Turbo Power, as it holds a 62% advantage in that metric. Choosing between these two components depends on whether your system requirements favor the expanded cache of the newer model or the power efficiency profile of the older unit.
