The Intel Core i5-12400 is the objective winner of this comparison, securing seven spec victories compared to two for the AMD Ryzen 5 2600. The most significant advantage for the Intel Core i5-12400 is its L2 cache, which is 150% larger than that of its competitor. While the AMD Ryzen 5 2600 maintains a 36% lead in base clock speed, this advantage is insufficient to overcome the broader technical superiority demonstrated by the Intel processor across the evaluated categories.

Users prioritizing cache capacity should select the Intel Core i5-12400 to leverage its substantial architectural advantage. Conversely, the AMD Ryzen 5 2600 remains a viable alternative for those specifically seeking the higher base clock speed provided by that unit. Choosing between these two components depends entirely on whether your specific requirements favor the increased L2 cache offered by the Intel model or the higher base clock frequency found in the AMD processor.
