The Intel Core i7-14700 is the objective winner of this comparison, securing victories in ten out of sixteen measured specifications. Its most significant technical advantage is its L2 cache, which offers a 100% improvement over the Intel Core i9-12900K. This substantial increase in cache capacity provides the primary edge for the newer processor, establishing it as the superior choice across the majority of the evaluated performance metrics.

Users prioritizing modern architecture and the benefits of expanded cache should select the Intel Core i7-14700 for their build. Conversely, the Intel Core i9-12900K remains a viable option for those who specifically require a higher base clock speed, where it maintains a 52% advantage. Choosing between these two components depends on whether your workload benefits more from the increased cache capacity of the newer model or the higher base frequency of the older unit.
