The AMD Ryzen 7 3700X is the objective winner of this comparison, securing a lead in ten out of fourteen measured specifications. Its most significant advantage over the Intel Core i7-9700K is its L3 cache, which is 167% larger. This substantial memory capacity provides the primary technical edge for the Ryzen processor, while the Intel alternative only manages to outperform its competitor in a single category across the entire field of tested specifications.

Users prioritizing memory-intensive tasks should choose the AMD Ryzen 7 3700X to leverage its superior L3 cache capacity. Conversely, the Intel Core i7-9700K is the appropriate selection for those who specifically require the 11% higher boost clock speed provided by that chip. Given the broader range of spec advantages held by the Ryzen 7 3700X, it remains the more versatile option for most general computing requirements compared to the Intel Core i7-9700K.
