The Intel Core i7-14700 is the objective winner of this comparison, securing victories in twelve out of fourteen measured specifications. Its most significant technical advantage over the Intel Core i9-10900K is its L2 cache, which is 1020% larger. This massive disparity in cache capacity serves as the primary differentiator between the two processors, establishing the newer model as the superior option across the vast majority of the evaluated hardware metrics.

Users prioritizing modern architecture and the substantial L2 cache advantage should select the Intel Core i7-14700 for their builds. Conversely, the Intel Core i9-10900K remains a viable choice only for specific use cases that rely on its 76% higher base clock speed. Most builders will find the newer component more capable, while those with highly specialized requirements favoring base frequency may still consider the older processor.
