The Intel Core Ultra 5 235F is the objective winner of this comparison, securing victory in eleven out of sixteen measured specifications. While the Intel Core i5-12400 holds a minor 2% advantage in MSRP, the Ultra 5 235F provides a substantial performance edge in memory architecture. The most impactful advantage of the newer processor is its L2 cache, which is 167% larger than that found in the older model, significantly enhancing its technical capabilities.

Users prioritizing the most advanced technical specifications should select the Intel Core Ultra 5 235F to leverage its superior L2 cache capacity. Conversely, the Intel Core i5-12400 remains a viable option for budget-conscious builders who specifically value the 2% MSRP advantage over the architectural improvements found in the newer unit. Choosing between these two processors depends entirely on whether your build requirements favor the latest cache technology or the slight cost benefit of the older hardware.
